Secret history of fresh meat moon cakes in Shanghai beach

Original Han Xiaoni’s guide to Shanghai residents’ life is included in the topic # Time-honored brand 1# Fresh meat moon cake 1.

The "moon cake season" is here again. The surging fresh meat moon cake industry in Shanghai is launching a new round of queuing time competition.

In fact, behind the uproar, Shanghai’s time-honored brands have many "secrets" about fresh meat moon cakes.

Where to start with too much material? Why don’t we start with the story of "Rashomon" between Guangming Village, Changchun and Harbin, the "Big Three" on Huaihai Road?

A long queue of fresh meat moon cakes in Guangming Village

Aunt, uncle and uncle came prepared.

I brought all the benches.

The Guangming Village on Huaihai Road is still in the same style this year, and the long queue to buy fresh moon cakes these days has been lined up to "Popeyes".

In fact, as early as late August, more than a month before the Mid-Autumn Festival, we found that this team "re-emerged".

A pot of 65 moon cakes and five boilers started in unison. In the afternoon of the working day, the long queue to buy moon cakes still blocked the alley next door.

An uncle in a white Polo shirt and a briefcase with one shoulder just squeezed out of the crowd and carried four boxes of fresh meat moon cakes in his hand.

"Allah’s age is more meticulous (careful), and I came to make a sample yesterday. I have to wait for an hour and a half in the morning, and the salesperson said that there will be fewer people in the next half day (afternoon). "

"I came over today to see that the team was quite long, and I bought it in less than 10 minutes."

"In fact, it is the most cost-effective to buy now, and you don’t suffer from queuing." My uncle is happy to share his "wrong peak" buying experience.

As early as late August,

Many customers came.

Cuofeng bought moon cakes.

"My name is lu, lu wan district. I am old Luwan, and buying this (moon cake) is nostalgic. " He said.

It turns out that the 73-year-old Lao Lu was born in Le ‘anfang opposite Guangming Village.

He came here to buy four boxes of moon cakes because there are four brothers and sisters, and he is going to send a box to the family.

Fresh meat moon cakes on Shanghai beach can be roughly divided into boiler pie and oven pie.

Lao Luting boiler pie. He said: "Now most of them are baked in the oven, and the baked grains are round, like steamed bread. Biting down is all flour, and it is stiff, indicating that the pastry is not done well. "

The fresh meat moon cakes in Guangming Village are baked in the boiler. "Its skin is crispy, and when you hold it in your hand, it looks like snowflakes layer by layer."

Belong to the "boiler school"

Both sides of the moon cake are flat.

I have bought it for many years, and Lao Lu even knows the "inheritance" of his mooncake skills clearly.

"It turned out that an old master was doing it himself in the first generation, and it was always good to eat the minced meat."

"We belong to the mouth is a knot in one’s heart. After the old master retired two years ago, we found that there was sugar in the stuffing, which was not delicious. Fortunately, it was changed back immediately after one year. "

"Now are two aunts in the roast. However, I think the master’s’ True Sutra’ has basically been handed down. "

Auntie used a pan.

On-site baking of fresh meat moon cakes

Has been "true" by the master.

In Shanghai’s "Fresh Meat Moon Cake List" commented by the public, Guangming Village currently tops the list and stands at the top of the contempt chain.

However, in the middle section of Huaihai Road (), which is characterized by cakes and cooked food and has successfully developed a "earthy taste", other time-honored brands are not "vegetarian".

Bright Village is not the only one selling fresh meat moon cakes.

Taikang, which has set up a baking counter for local products all over the country, and Laodafang in the South District, which has just opened its store, are "away from home", but the price is set at "proud", and one fresh meat moon cake is sold in 6 yuan.

Changchun Food Store and Laodachang are "old lands", and the price of fresh meat moon cakes is the same as that of Guangming Village, so they sell one from 5 yuan.

Laodachang is also a "boiler pie", and there is a pan in the shop that is now for sale.

Do it now and sell it now

There are many people who like it.

Although the popularity is not as good as that of Guangming Village, there are people queuing in twos and threes from time to time at the counters shared by Liuxin Egg-yolk Crisp, Barbecued Crisp and Coconut Roll.

In contrast, Changchun treats fresh meat moon cakes more seriously and has set up a special counter.

Its fresh meat moon cakes are usually "oven pie", but near the Mid-Autumn Festival, the variety of traditional boiler baking has recently been added.

Changchun food store

Specially set up a fresh meat moon cake counter.

The poster emphasizes the use of Eisen meat.

Speaking of fresh meat moon cakes, Changchun sighed.

The so-called "thirty years in Hedong, thirty years in Hexi", once upon a time, fresh meat moon cakes in Changchun were the "king of popularity" in this street.

"Allah was originally artificial, baked with a pan of charcoal fire, and began to do it in 1997." Insiders in Changchun said, "There are about ten years in Guang Chen, and Allah has done a good job."

Changchun is now all year round.

Fresh meat moon cakes baked in an oven

Add "Boiler Edition" before Mid-Autumn Festival.

In this regard, insiders of Guangming Village also admit that fresh meat moon cakes in Changchun sold better than them at first.

As for how to catch up with it later, insiders in Guangming Village say:

"One year after the renovation (referring to Changchun), Allah began to overtake. In fact, we were ready before this, and the quality was quite tight. So I rushed out once I had the chance. "

In this regard, Changchun is noncommittal, just saying: "We are ancestors of fresh meat moon cakes." He also revealed that Guangming Village had learned from them in his early years.

I heard that the fresh meat moon cakes in Changchun are "ancestors", and Harbin Food Factory laughed.

An old mage who worked in Harbin Food Factory for many years told us: "We first taught Changchun fresh meat moon cakes."

The origin is this:

Harbin and Changchun belong to Shanghai Tobacco Group.

"Changchun was originally just a retail store. They want to diversify and be a’ front shop and back factory’-the workshop upstairs produces moon cakes and then sells them in the shop downstairs. "

Therefore, as a brother unit of the same group, Harbin is duty-bound to teach the skills of making moon cakes.

In Harbin, which started with Russian West Point, fresh meat moon cakes are actually well-founded. Because a few years ago, Gao Qiao Food Factory was merged into Harbin.

Back then, Gao Qiao Food Factory’s fresh meat moon cake was also a famous brand on Huaihai Road.

In 1983, it was reported in Wen Wei Po that Gao Qiao Food Factory on Huaihai Road insisted on supplying fresh meat, moon cakes and other special varieties, which were well received by consumers.

In Wen Wei Po in 1983.

There is even a saying that the predecessor of fresh meat moon cakes is Gao Qiao muffins.

Gao Qiao muffin is one of the four famous spots in the ancient town of Gao Qiao, which has a history of one hundred years. Among them, Gao Qiao muffins with fresh meat stuffing are crispy and juicy, which is said to have gradually evolved into fresh meat moon cakes.

Now that Changchun and Guangming Village are leading the way, the old master of Harbin admits: "The apprentice defeated the master."

In this regard, Harbin is also calm: "Their meat stuffing is wrapped on the spot and baked very fresh. Unlike our meat stuffing, it was delivered after being frozen in the factory on Quxi Road. "

"So we thought about it, and our focus is not on fresh meat moon cakes."

The "Big Three" on Huaihai Road have their own opinions about fresh meat moon cakes, which have been interpreted as a "Rashomon" story.

Looking at the whole country, Shanghai may be the city that loves fresh meat moon cakes most. Hungry take-away data show that last year, Shanghainese ate 53% of the country’s fresh moon cakes.

When did Shanghainese begin to like fresh meat moon cakes? It is probably impossible to test the age.

However, we can see from the database that as early as 1928, an advertisement for old Yuchang fresh meat moon cakes on Aiduoya Road (now Yan ‘an East Road) was published in Shenbao.

This advertisement in Shenbao, a bus stop at Sinan Road, Huaihai Middle Road, said

Lao Yu Chang de Xiao zhi fresh meat moon cake

"Choose the best ingredients, so it’s delicious."

Regarding the origin of fresh meat moon cakes, the version introduced by the real boss room is that in the past, there was a kind of fresh meat dumplings that was very popular in Soviet-style tea.

Its outer skin is brown and crispy, the middle layer is delicate and crisp, and the inner layer is fresh and firm meat stuffing.

Later, a master "opened his brain wide" and changed the shape and size of fresh meat dumplings, which became fresh meat moon cakes.

Belong to "oven pie"

There are also many fans.

On September 14th, 1980, Liberation Daily reported that there were 147 units producing moon cakes in Shanghai catering industry that year, among which 127 households produced fresh meat moon cakes.

In Liberation Daily in 1980.

Report on Mid-Autumn Moon Cake

Two years later, Wen Wei Po reported that on the eve of Mid-Autumn Festival, nearly 200 restaurants in this city served fresh meat moon cakes. In order to meet the needs of consumers, the supply of fresh meat moon cakes this year increased by about 50% compared with the previous year.

The supply of stores and output both increased because "fresh moon cakes are crispy in skin, big in stuffing, fresh and bittern in meat, salty and sweet, and have a unique flavor. Generally, they are sold now, baked while cooking, and full of fragrance, which is very popular among consumers."

In 1989, Liberation Daily continued to report that "the sales of sweet moon cakes dropped sharply, but the sales of fresh moon cakes soared."

"Salty moon cakes are the most popular ones, so there are more than 70 shops selling fresh meat moon cakes on the streets of Shanghai this year, and even some fresh meat moon cakes made by big cake stalls are queued, which is in short supply."

In Liberation Daily in 1989

Report on Mid-Autumn Moon Cake

According to the report, fresh meat moon cakes are favored because the tastes of Shanghainese are changing.

"A customer who queued up in front of Yuelaifang Food Store in Putuo District told the reporter: Nowadays, moon cakes are like sugar cakes, which are too sweet and expensive. They are not as good as cheap and good meat moon cakes, which are fresh and fragrant."

By the way, Yue Laifang, who lives in the west of Shanghai, also has a name in the "History of Fresh Meat Mooncakes in Shanghai". Many people believe that fresh meat moon cakes were first sold by Yue Laifang.

It can be seen that over the years, Shanghai people’s preference for fresh meat moon cakes has been increasing day by day and has never been reduced.

If we say that the "love and hate" between Guangming Village, Changchun and Harbin on Huaihai Road around fresh meat moon cakes is a story of nearly twenty years.

Then, on Nanjing Road, another famous commercial street in Shanghai, the real old house has been famous for a long time.

Before the Mid-Autumn Festival in 2003

The queue of the real boss’s room is grand

/Shao Jianping photo

As early as 1982, it was reported in the newspaper that the fresh meat moon cakes in the real boss’s room won the first prize in the quality appraisal of moon cakes by catering companies in the city.

In 1986, Xinmin Evening News reported, "The fresh meat moon cakes produced by this store pay attention to the strict control of specifications and quality, and the minced meat is all lean-legged meat. Since its listing, the daily sales volume has reached about 3,000 kilograms. "

In Xinmin Evening News in 1986

A report on the real boss’s house

In 2005, the Jiang Shen Service Herald wrote: "Every year’s’ moon cake season’, there will be amazing all-weather’ long queues’ here, sometimes even winding more than 100 meters!"

However, on Nanjing Road, the real boss has a close competitor-Taikang.

Public comment

Netizens like the mooncakes of the two families.

Compare them.

In 2011, "Morning News" took stock of the "queuing index" of the time-honored fresh meat moon cakes in Shanghai. The two companies are comparable, and the queue time is about 6 hours.

A report in the Morning News in 2011

Inspected the time-honored brands.

"queuing index" of fresh meat moon cakes

What I want to tell the people who eat melons quietly here is that these two food stores with their own fans are actually "a family"-both belong to Taikang Food Co., Ltd.

Some people go to Huaihai Road and Nanjing Road to queue up to buy moon cakes every year, but in the eyes of citizens in the western district, the fresh meat moon cakes in the old house in the western district are the best ones.

The story of the real boss’s house and the old boss’s house in the west end of the country, which was taught by the same family in the early years, has been "eight" before, so we can’t press it here.

The fresh meat moon cakes of these two companies have always been equally famous, ranking almost the same.

We went through the newspaper pile again, and in 1982 and 1986, when the real boss room was reported, the boss room in the west side was also reported.

"At the entrance of Jing ‘an Temple’s’ Western District Old House’, customers often queue up to buy fresh meat moon cakes. An old uncle praised:’ the fresh meat moon cakes here are delicious and keep on selling all year round.’ ….. Near the Mid-Autumn Festival, the business of "the old house in the west side" is better. On September 7th, more than 14,700 fresh meat moon cakes were sold. "

-Xinmin Evening News, September 08, 1982, "The fragrance of cakes is accompanied by the fragrance of osmanthus"

Just like the real boss’s room.

The old house in the west side is also often there.

Appeared in reports about fresh meat moon cakes.

"The special fresh meat moon cakes produced by the old house in the west area of Jing ‘an Temple this year are among the best in the evaluation of the city tobacco and sugar company."

-Xinmin Evening News, September 12, 1986, "Fresh meat moon cakes here are welcomed by customers"

They all say "orange in the south and orange in the north". Last year, our old friend, folk photographer Shou Yousen, saw in Jing ‘an Temple that the fresh meat moon cakes in the old house in the West District were treated in line as usual.

Taikang, who had a long queue on Nanjing Road, opened the counter next to the old house in the west, but it was deserted. .

Seeing Taikang, which is very popular on Nanjing Road.

It’s cold next door to the old house in the west side

Shouyousen sent a circle of friends.

It seems that Shanghainese eat fresh meat moon cakes, which are not only delicious, but also famous and lively.

Rare in the world! One tunnel, eight kinds of poison gas, but they go against the trend

  Cctv newsIn Lincang, Yunnan Province, deep in the boundless mountains, there is a 10,000-meter-long tunnel under construction at the construction site of the China-Myanmar International Passage, named "Hongdoushan Tunnel". Because of the special geological conditions, there are 8 kinds of toxic gases in the tunnel, accompanied by high temperature of 40 degrees, water inrush and mud outburst.

  This is the boundless mountain, which stretches for hundreds of miles, majestic and steep, and the only China-Myanmar international corridor leading to Myanmar is under construction in China, which passes through here. Among them, the control project, Hongdoushan Tunnel, is located in the hinterland of the boundless mountains, adjacent to the Lancang River, with a maximum buried depth of 1020 meters. But no one expected that the mysterious and beautiful boundless mountains are rich in eight kinds of toxic and harmful gases, such as hydrogen sulfide, carbon monoxide and carbon dioxide, due to extremely special geological conditions. The first echelon workers in charge of tunnel excavation must wear gas masks during construction.

  The toxic gas in the tunnel seems to be trapped in balloons and hidden in the rocks of the boundless mountains. Once these toxic balloons are punctured during construction, the toxic gas will explode. In 2017, the construction team that just entered the site for one year, due to insufficient research and treatment experience of toxic gases in the tunnel, led to a gas outburst accident in Hongdoushan Tunnel. Subsequently, two-thirds of employees applied for evacuation from the construction site, and the project was once at a standstill.

  Just then, Zhao Yu, who has 20 years of experience in tunnel construction, was ordered to come here.

Zhao Yu, manager of Dalin Railway Project Department of China Railway 10th Bureau.

Zhao Yu, manager of Dalin Railway Project Department of China Railway 10th Bureau.

  Zhao Yu, manager of Dalin Railway Project Department of China Railway 10th Bureau.Everyone has no retreat, so we leaders, from myself, have no retreat and must stand in the front line.

  Zhao Yu and Quan Fei, who was demoted to deputy chief engineer because of the sudden explosion accident, gathered the employees in the project team who had not been evacuated and formed a new team. Everyone should go against the trend.

  A tunnel contains many mysterious poisonous gases. This kind of difficulty, which is rare in the world, is a rare opportunity in the eyes of the brave. The new team invited experts from various fields to conduct in-depth investigation, and must thoroughly understand the poisonous gas in Hongdoushan Tunnel.

  After investigation by experts, the extremely dangerous area of toxic and harmful gases in Hongdoushan Tunnel reached 5764 meters, accounting for more than half of the total length of the tunnel. Everyone agrees that the rare geological environment conditions and the complex and changeable gas composition of Hongdoushan Tunnel have exceeded the cognitive level of current geological exploration technology, and its prevention measures are still in the stage of research and exploration.

  This conclusion of the expert group means that the construction party cannot get more help from the past experience and technology.

  Every step is exploration, but once the road is explored, it is the way to get rid of the predicament.

  After the tunnel air is thoroughly disinfected and ventilated, the second echelon personnel can take off their gas masks and enter the construction site. Eight kinds of toxic gas dilemmas in Hongdoushan Tunnel have finally been broken through in actual combat.

  On August 17th, last year, there was another danger of water gushing in the No.2 inclined shaft of the tunnel. Although the construction can be continued after 37 days of pumping and drainage, now, the constantly gushing water will still flood some construction areas, and the workers need to stand waist-deep in the water all the time.

  Eight kinds of poisonous gas, high temperature and sudden mud gushing are not only the first time in the history of tunnel construction in China, but also rare in the world. The team of Hongdoushan Tunnel has constantly solved various rare problems in the construction, but it has also accumulated very valuable experience and technology for tunnel construction in China.

  In June this year, the first batch of patents and academic papers based on the construction of Hongdoushan Tunnel will be published soon. By the end of this year, the scientific research results involving six patents will also be fully launched.

  At present, the construction of Hongdoushan Tunnel has exceeded 3,000 meters, and the key project of China-Myanmar International Corridor — — The construction of Dalin Railway is also progressing steadily. After it is completed and opened to traffic in 2021, it will play a positive role in improving the railway network in western China and highlighting the interconnection of infrastructure between Yunnan and neighboring countries.

Popular science | What is air pollution? What are the main pollution sources?

atmospheric pollution

What is it?

Air pollution is a phenomenon that some substances enter the atmosphere due to human activities or natural processes, showing sufficient concentration for enough time, and thus endangering human comfort, health and welfare or the environment.

Air pollutants enter the atmosphere (input) from man-made or natural sources, participate in the circulation process of the atmosphere, and are removed (output) from the atmosphere through chemical reactions, biological activities and physical sedimentation after a certain retention time. If the output rate is less than the input rate, it will be relatively concentrated in the atmosphere, resulting in an increase in the concentration of a substance in the atmosphere. When the concentration rises to a certain extent, it will directly or indirectly cause acute and chronic harm to people, organisms or materials, and the atmosphere will be polluted.

1. Sources of air pollutants

(1) Natural sources of air pollution

Volcanic eruption: H2S, CO2, CO, HF, SO2 and volcanic ash are emitted.

Forest fire: CO, CO2, SO2, NO2, HC, etc. are emitted.

Natural dust: wind sand, soil dust, etc.

Forest plant release: mainly terpene hydrocarbons.

Wave droplet particles: mainly sulfate and sulfite.

In some cases, natural sources are more important than man-made sources. According to relevant statistics, 93% of global nitrogen emissions and 60% of sulfur oxide emissions come from natural sources.

(2) Man-made pollution sources

The atmospheric pollution source usually refers to the source of pollutants transported to the atmosphere by human activities. Man-made pollution sources of the atmosphere can be summarized as the following four aspects:

Fuel combustion: the combustion process of fuels (coal, oil, natural gas, etc.) is an important source of pollutants to the atmosphere. The main component of coal is carbon, and it contains hydrogen, oxygen, nitrogen, sulfur and metal compounds. In addition to a large amount of smoke and dust, carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen oxides, organic compounds, smoke and dust and other substances are also formed during the combustion process.

Emissions from industrial production processes: such as hydrogen sulfide, carbon dioxide, sulfur dioxide and nitrogen oxides emitted by petrochemical enterprises; Sulfur dioxide, nitrogen oxides and dust containing heavy metal elements discharged by nonferrous metal smelting industry; Fluoride emitted by phosphate fertilizer plants; Sulfur dioxide, nitrogen oxides, hydrogen chloride and various acidic gases discharged from acid-base salinization industry; The iron and steel industry discharges dust, sulfur oxides, cyanide, carbon monoxide, hydrogen sulfide, phenol, benzene and hydrocarbons in the process of ironmaking, steelmaking and coking. The composition of pollutants is closely related to the nature of industrial enterprises.

Emissions during transportation: The tail gas emitted by automobiles, ships and airplanes is the main source of air pollution. The exhaust gas emitted by internal combustion engine contains carbon monoxide, nitrogen oxides, hydrocarbons, oxygen-containing organic compounds, sulfur oxides and lead compounds.

Emissions from agricultural activities: when pesticides are applied in the field, some pesticides will escape into the atmosphere in the form of dust and other particles, and those remaining on crops or adhering to the surface of crops can still volatilize into the atmosphere. Pesticides entering the atmosphere can be absorbed by suspended particles and transported to various places with the airflow, causing atmospheric pesticide pollution. In addition, there are straw burning.

China has enacted "People’s Republic of China (PRC) Environmental Protection Law" and formulated national and regional "waste gas emission standards" to reduce air pollution and protect people’s health.

2. Harm of air pollution

(1) Harm to human body

The harm of air pollutants to human body is various, mainly manifested in respiratory diseases and physiological dysfunction, as well as the irritation of mucous membranes such as eyes and nose, which is a chronic factor causing asthma in the elderly. Insufficient lung qi leads to physical decline.

The influence of air pollution on human body is firstly uncomfortable, then there is a reversible reaction in physiology, and then there are acute harmful symptoms. The harm of air pollution to people can be roughly divided into three types: acute poisoning, chronic poisoning and carcinogenesis.

1. Acute poisoning

When the concentration of pollutants in the air is low, it usually does not cause acute poisoning, but under some special conditions, such as special accidents in the production process of factories, a large number of harmful gases leaking out, and sudden changes in external meteorological conditions, it will cause acute poisoning of people. For example, methyl isocyanate leaked from Pabor pesticide plant in India directly harmed human body, with 2,500 people killed and more than 100,000 injured.

2. Chronic poisoning

The chronic toxic effect of air pollution on human health is mainly manifested in the phenomenon that the prevalence rate increases after pollutants are exposed to human body in low concentration for a long time. The incidence of lung cancer among urban residents in China is very high, the highest of which is in Shanghai, and the respiratory diseases of urban residents are significantly higher than those in suburbs.

3. Carcinogenesis

This is the result of long-term influence, because pollutants act on the body for a long time, damaging the genetic material in the body and causing mutation. If the germ cells mutate, all kinds of abnormalities will appear in the offspring, which is called teratogenicity. If the genetic material and genetic information of organism cells suddenly change, it is also called mutagenicity; If the tumor is induced, it is called carcinogenesis. The "cancer" referred to here includes benign tumors and malignant tumors. Carcinogens in the environment can be divided into chemical carcinogens, physical carcinogens and biological carcinogens. The process of carcinogenesis is quite complicated, generally including initiation stage and growth promotion stage. Factors that can induce tumors are collectively referred to as carcinogenic factors. Tumors caused by long-term exposure to carcinogenic factors in the environment are called environmental tumors. Air pollution will reduce people’s life span.

(2) Harm to plants

Air pollutants, especially sulfur dioxide and fluoride, are very harmful to plants. When the concentration of pollutants is very high, it will cause acute harm to plants, causing damage to the surface of plant leaves, or directly causing leaves to wither and fall off; When the concentration of pollutants is not high, it will cause chronic harm to plants, make the leaves of plants fade green, or there are no harmful symptoms on the surface, but the physiological functions of plants have been affected, resulting in the decline of plant yield and deterioration of quality.

(3) Harm to the climate

Air pollutants can also affect weather and climate. Particulate matter reduces atmospheric visibility and reduces the amount of solar radiation reaching the ground. Especially in large industrial cities, the sunlight is 40% less than normal when the smoke is not scattered. The pollutants in the upper atmosphere, such as nitrogen oxides, hydrocarbons and chlorofluorocarbons, decompose ozone in large quantities, causing the "ozone hole" problem, which has become the focus of global attention.

The increase of greenhouse gases such as carbon dioxide will lead to the warming of the earth’s atmosphere and the increase of global weather disasters. Another example is the increase of aerosol particles such as smoke and dust, which will increase atmospheric turbidity, weaken solar radiation and affect the long-wave radiation of the earth, which may lead to abnormal weather and climate.

(1) Reduce the amount of solar radiation reaching the ground: A large number of smoke particles discharged into the atmosphere from factories, power stations, automobiles and household heating equipment make the air very turbid, which blocks the sunlight and reduces the amount of solar radiation reaching the ground. According to observation and statistics, in the days when the smoke is not scattered in large industrial cities, the amount of direct sunlight hitting the ground is reduced by nearly 40% compared with the days without smoke. In cities with serious air pollution, it will lead to poor growth and development of people, animals and plants due to lack of sunlight every day.

② Increasing atmospheric precipitation: many of the particles discharged from large industrial cities have the function of condensation nuclei of water vapor. Therefore, when there are other precipitation conditions in the atmosphere, there will be precipitation weather. In the downwind areas of big industrial cities, there is more precipitation.

③ Acid rain: Sometimes, the rain falling from the sky contains sulfuric acid. This kind of acid rain is formed by the oxidation of sulfur dioxide, a pollutant in the atmosphere, to form sulfuric acid, which falls with the precipitation in nature. Sulfuric acid rain can destroy large areas of forests and crops, corrode and break paper products, textiles and leather products, deteriorate metal antirust coatings and reduce their protection, and corrode and pollute buildings.

3. How to prevent and control air pollution in life

1. Don’t litter; Travel by bus and subway as much as possible, reduce the use of private cars, and buy new energy vehicles; Participate in greening activities such as planting trees; Private cars are equipped with tail gas treatment devices, and lubricating oil is used to fully burn fuel and reduce harmful gas emissions.

2. On holidays, instead of setting off fireworks and firecrackers, electronic firecrackers can be used instead, no outdoor barbecue, no burning of straw and leaves, and less coal burning to reduce air pollution.

3. Reduce the use of freon-containing air conditioners and refrigerators, and suggest purchasing new energy-saving products.

4. Reduce going out in foggy weather (according to relevant explanations, Ozone refers to ozone, while PM2.5 refers to fine suspended particles with a diameter of less than 2.5 microns, also known as particles that can enter the lungs. This suspended particle is a "health killer" in the air. Extensive damage to respiratory system, heart and blood system).

5. Wear a mask when going out (factors such as mask material, service life and technical level are the criteria for defining the quality of masks. If consumers have no special needs, they don’t have to snap up "concept masks" marked with various functions).

6. It is everyone’s responsibility to prevent and control air pollution. It is the right given to every citizen by law to report and accuse acts that pollute and destroy the environment. When encountering uncivilized acts that pollute the atmosphere, actively report them, jointly safeguard the beautiful blue sky and build a happy Zhuzhou!

  Huawei launched AX3 series, the world’s first Wi-Fi 6+ router, with strong quad-core performance of+3,000 Mbps.

  Last year, Wi-Fi 6 was officially released, which supported Wi-Fi&ensp in the early days; 6 devices include Galaxy  Note10、Galaxy  S10 and the iPhone 11 series just released by Apple, most (if not all) flagship devices may support Wi-Fi&ensp from now on; 6。 As the name implies, it is the sixth generation of Wi-Fi. On October 3, 2018, Wi-Fi Alliance officially brought Wi-Fi based on IEEE 802.11ax standard into the regular army and became the sixth generation Wi-Fi technology, namely Wi-Fi 6. Like 5G, the most intuitive change brought by Wi-Fi 6 is the improvement of network speed. The highest transmission rate can reach 9.6 Gbps, which is equivalent to the download speed of 1.2GB/s, which is 40% higher than the previous generation of Wi-Fi.

  However, Huawei is different. At the Huawei conference on February 24th, Huawei released the world’s first Wi-Fi 6+ router, which has strong quad-core performance, wireless rate as high as 3000Mbps, and convenient functions such as NFC touch networking. Huawei is a TOP 2 contributor to the Wi-Fi 6 standard. On the basis of Wi-Fi 6, Huawei launched Wi-Fi 6+, which greatly improved the performance of Wi-Fi.

In addition to the local APP store, Huawei has also launched Quick Apps, which is already in use in China. This kind of app does not need to be installed, and it is a web-based application like a small program. When it is used up, it takes up little space.

  One big event: P40 series mobile phones released on March 26th.

  Finally, Yu Chengdong, CEO of Huawei Consumer Terminal, also announced a major event — — On March 26th, Huawei will release P40 series mobile phones in Paris, which Yu Chengdong said is the strongest 5G flagship mobile phone in the world.

Eight newly-opened special spas in the world interpret luxury in a low-key way (5)

New york Halo spa

Experience the magic of salt SPA in salt cave
Experience the magic of salt SPA in salt cave

 

    Since salt is used as a spa, why should I come here and go directly to the seaside? To tell you the truth, Ray thinks so, too. However, it is said that "this newly-opened Halo spa in new york can treat asthma and drive away the cold". I can’t help but make little Ray curious.

    Located in Manhattan, Halo Spa is the first of its kind in the United States, and it acts like a salt cave in Eastern Europe (like Slovakia).

    Ray told me, "Halo spa also has a children’s room. The children’s room looks like a fairyland, which is very suitable for bringing children." Salt is imported from Ukraine, and it is on the walls and floors, and there are fine salt particles in the air, just like salt spray.

    "I can even smell a smell of salt when I bring my daughter," Ray has always been a man with strong action and keen to reveal secrets. "Maybe I’m afraid that children can’t stay, and there are many toys, rocking wooden horses and TVs in it."

    It is said that this therapy is very popular in Israel. Moreover, it is said that salt therapy can also treat skin diseases, heart diseases, vascular diseases and relieve fatigue and depression, and it is also helpful to quit smoking. That said, I think it should be promoted vigorously in China, so that adults and children don’t have to worry about catching a cold in cold places.

 

London The Dorchester Spa

Meet the popular SPA of Hollywood stars
Meet the popular SPA of Hollywood stars

 

    The renovated and reopened Dorchester spa is regarded as the best spa in Britain in 2010. The location is good. The environment in the Mayflower District is absolutely unparalleled in London. The Dorchester Hotel is also famous as the "best business hotel". It is said that each guest has three employees to serve it.

    Gillian, a friend from London, described it as "I know this newly renovated spa is good, but I didn’t expect it to be so good". Unlike traditional spa rooms, which all have a front desk, Dorchester spa is led by a special person directly through a dark aisle to a rest area, with a platinum mirror screen behind it. The highlight of the design is the curtain made of 72,000 South African pearls designed by Linton. Luxury is naturally everywhere, such as sofas and beds inside. If you want to show off, the spa room can really be made into a brand museum. Care products are no exception. Body care products include Vaishaly,Carol Joy London (ask Londoners about the popularity of these two products) and Kerstin Florian (first appeared in the spa room in London).

    Some details in the SPA are also very popular, such as the sound insulation effect of the nursing room is very good. This point was carefully considered when redecorating.

    Dorchester Hotel is a favorite hotel of Hollywood stars, so maybe when you are resting in public space, you will be sitting next to a star who has been in the limelight recently. When Harry Potter and The Lord of the Rings premiered in London, hotels were the first choice for holding receptions and staying with superstars. Sometimes you have to think, isn’t this luxury a bit too much?

  The scale of cross-border e-commerce transactions has grown rapidly in recent years. In 2013, according to iResearch’s estimation, the transaction volume of cross-border e-commerce in China was about 3.1 trillion yuan, with a compound annual growth rate of 31.1% from 2008 to 2013, accounting for an increasing proportion of the total import and export trade. At present, China’s cross-border e-commerce trade is still dominated by exports, accounting for more than 80%, but the proportion of import trade is also gradually increasing.

  Geographically, each region is also developing regional cross-border trade e-commerce. In 2012, the National Development and Reform Commission and the General Administration of Customs approved Shanghai, Chongqing, Hangzhou, Ningbo and Zhengzhou as pilot cities for cross-border trade e-commerce. In 2013-14, some cities were successively included in the pilot cities of cross-border trade e-commerce. Cities such as Yiwu and Xiamen have begun to focus on building local cross-border trade e-commerce platforms, logistics platforms and payment platforms. Since 2013, cross-border trade e-commerce in all regions has achieved rapid growth.

  In the process of e-commerce of traditional cross-border trade, the business in emerging markets has grown very rapidly. In 2013, in China’s export trade, the total export volume of the United States, Japan and Europe accounted for about 39%, while Africa and Latin America accounted for about 4% and 6% respectively. In the field of export e-commerce, statistics from EBAY and Alibaba show that the cross-border trade volume and growth rate of Argentina, Israel, Russia, Brazil and other countries are particularly prominent.

  China’s annual export trade scale is at the level of 10 trillion RMB, and the market space is huge. In 2013, China’s export trade reached 2.2 trillion US dollars (about 13.6 trillion RMB), and the total import and export trade was about 4.2 trillion US dollars. According to iresearch, in 2013, China’s cross-border e-commerce transaction volume was 3.1 trillion RMB. Massive market demand has brought huge growth space for the development of e-commerce in cross-border trade.

  From the perspective of subdivided products, most export categories are suitable for expanding e-commerce channel sales.

  According to the data of the General Administration of Customs in the first half of 2013, more than 50% of China’s export commodities are mechanical and electrical products, and labor-intensive products such as textiles and clothing account for about 20%. Compared with bulk raw materials, consumer goods such as mechanical and electrical products and textiles are less difficult to trade e-commerce. From the perspective of commodity structure, China’s export e-commerce space is also considerable.

Nanjing: 204 confirmed cases were found in more than 26.61 million copies of three rounds of nucleic acid testing for all employees in the city.

  Today (August 1st), Nanjing held a press conference on the prevention and control of COVID-19 epidemic, and continued to report the epidemic situation and prevention and control trends. Up to now, more than 26.61 million copies of nucleic acid tests have been carried out by all employees in Nanjing, among which 204 confirmed cases have been found through nucleic acid tests.

  Yang Dasuo, deputy director of the Nanjing Municipal Health and Health Commission, introduced that the first round of nucleic acid testing for all employees in the city was 9.2336 million, of which 74 cases were confirmed; The second round of large-scale nucleic acid detection was 8.478 million copies, of which 81 cases were confirmed; By 24: 00 on July 31, the third round of large-scale nucleic acid testing had sampled 8.9 million samples, of which 8.76 million samples had been tested. By 24: 00 on July 31, 49 confirmed cases were found.

  From the source of 204 confirmed cases in Nanjing, there are 93 people in centralized isolation point, 36 people in home isolation, 48 people in key personnel screening, 12 people taking the initiative to seek medical treatment and 15 people in community screening. In terms of regional distribution, it is distributed in 9 districts such as Jiangning District and Lishui District, among which there are 174 cases in Jiangning District, accounting for 85.3%, and 11 cases in Lishui District, accounting for 5.4%, which means that Jiangning District and Lishui District account for 90.7% of the total. According to the analysis, the cases are mainly concentrated in Nanjing Lukou Airport and surrounding areas, and the cases found are mainly from the key groups that were included in the control in the early stage. Most of them were found in the verification of key groups in centralized isolation and home isolation, and there are also a few sporadic cases.

  According to Yang Dasuo’s analysis, the total number of nucleic acid samples collected by all employees in the city has changed in three rounds, of which the second and third rounds are less than the first round, because some qualified college students left Nanjing for holidays and other reasons. In addition, the number of samples in the second round was significantly lower than that in the first round, and other streets such as Jiangning and Lukou carried out the second round of testing ahead of the whole city, and the relevant sampling numbers were included in the figures of the first round of sampling. At present, there are 12 provincial, municipal and district centers for disease control and prevention in Nanjing, and the city’s single-tube nucleic acid detection capacity has exceeded 700,000 copies per day.
