Some of the best thing in life don't happen until you grow old enough to recognize them. I can say that about tea. .

    I didn't start to drink tea until I was 35. The first time felt a genuine urge to drink tea was in 2003, when I stayed briefly in the United Kingdom. After a time of consuming local food, I started to really like strong black tea.

    I took packs of green tea with me as gifts but was disappointed to find my British friends preferred much stronger black tea from Sri Lanka. Later I learned that although people know China for its tea, it ranks only third among the world's black tea exporters, after Sri Lanka and Kenya.

    After I came back to China and started to cover food stories, I met friends in the tea-drinking circle and learned more. Although the majority of the rest of the world drinks black tea, which the Chinese call “red tea”, China processes and drinks mostly green tea.

I feel lucky to be Chinese because of the great variety of tea available in the county. It is estimated that there are more than 2000 tea in China it you divide them geographically,] including more than 600 locally famous tea. A more simple way to categorize it is by color ； and extent of fermentation(发酵). That comes down to six main categories — green, white, yellow, dark greenish(oolong), red and black tea.

    Tasting tea can be compared to our life. It can be plain and predictable but sometimes it is j full of pleasant surprises. Occasionally it can even seem too good to be true. The best thing is, you know there's always more to explore.

    Relieving poverty has been one of our government's top concerns for the past decades. Poverty(贫困) in remote areas in China is virtually a great obstacle for the Chinese to get common progress; thus, it is urgent for us to help the people there to shake off poverty the sooner the better. For this aim, the government has already sent technicians and experts to poverty-stricken areas to help boost local agricultural production and teach the locals new techniques. The Ministry of Labor has also trained many rural laborers through different programs. But all these are not enough. Several other ways have been proposed as follows.

    First of all, the government should encourage a small part of the people in the remote areas to get wealthy ahead of others by equipping them with relevant funds and agricultural technology. These “better-offs” can not only set a good example but give confidence to the poorer in their efforts to get rid of poverty. When all the people get rich, the general level of living standard can be greatly improved. With their living standard improved, they can attach greater importance to environmental protection and are willing to input considerable amount of money to educate their children. Only in this way is a sustainable development guaranteed.

Secondly, we must call upon people in all walks of life throughout the country, especially those wealthy citizens in coastal areas to help those struggling below poverty line in poor remote regions out. We must realize that only after all Chinese people live a comfortable life can we be peacefully enjoying material prosperity in life. Helps can come in various forms—-donating money to the poor family and books to school drop-outs, college graduates volunteering to work in the most needed regions, bringing knowledge to them, etc.

    The last but not the least, the government should raise the rate of tax on the rich. This can shorten the gap between the poor and the rich as well as benefit the country's revenues(财政收入) whose better part is in turn allocated to the poor remote areas.

    Admittedly, it is never easy to cast off the shadow of poverty in the remote areas completely in the short run. But every one of us should go all out to help those in poverty, we are confident that our country will be more powerful and prosperous in the process of relieving poverty.

    Chewing gum(口香糖) has its origins in ancient times from Mayans to Greeks who would chew the resin(树脂)of certain trees for medical purposes and maybe even for freshening breath. The history of chewing gum continued as Native Americans introduced it to European settlers.

    Chewing gum hit the market after Santa Anna brought a case of chicle(糖胶树脂) from Mexico to New York. Santa Anna gave some to the part-time inventor Thomas Adams Thomas Adams changed the gum and marketed it as a candy. The invention took off and was known as Chiclets.

    In 1900 Frank Fleer coate chewing gum with sugar, and in 1906 Blibber Blubber was invented, but never made it to market. Blibber Blubber was too sticky and it was also too difficult to remove the burst bubble(破了的泡泡) from one's skin without using some special tools.

    A history of bubblegum just wouldn't be complete without mentioning the gumball machine, which popularized gum. The first gumball machine came onto the scene in 1907 and sold sugar-coated chewing gum.

    However, it wasn't until 1928 that bubblegum was created. Walter Diemer, working for Frank Fleer's gum company, discovered bubblegum by accident while experimenting in the lab during his breaks. The gum was named Dubble Bubble. Pink was the only color which could be used at the time, and Dubble Bubble has remained pink ever since.

    According to the International Chewing Gum Association,during WWII Dubble Bubble was handed out by US military members as gifts, thereby spreading its popularity among the peoples of Europe, Africa, and Asia. And in the 1930s he first bubblegum cards appeared. "the pictures changed from war heroes to Wild West figures to professional athletes."

    Bubblegum has been popular ever since, especially among children, thanks to its inventive shapes, and sugary flavors, from original bubblegum to a yardstick of fruity bubblegum.

Lack of sleep among children and teenagers in China has worsened in the past decade, with more than 80 percent getting insufficient sleep on school days, a new report has found.

Chinese youngsters snooze 7. 8 hours a night on average on school days, down 0. 3 hours from 2009, according to the report released on Monday by the Chinese Academy of Sciences'Institute of Psychology.

Researchers surveyed more than 15,800 students from Henan, Hebei and Guangdong provinces from April to July, asking what time they go to bed and wake up on days they take offline classes on campus.

Only 46. 4 percent of them sleep for at least 8 hours, compared with 47. 4 percent in 2009.

According to an action plan laying out measures to be taken from 2019 to 2030 to promote the health of citizens, primary school students are recommended to get a minimum of 10 hours of sleep a night. For junior high school and senior high school students, the recommended sleep durations per night are 9 and 8 hours respectively.

By this set of standards, more than 95 percent of students from primary schools, nearly 91 percent at junior high and 84 percent at senior high, did not get enough sleep on school days, heightening the risk of them developing cognitive, mental and physical health problems, the report said.

Hou Jinqin, a researcher at the National Institute of Education Sciences who co-authored the study, suggested local authorities implement measures instructed by the Ministry of Education, such as lessening academic burdens, postponing start times at school and encouraging children to be enrolled at institutions closer to home, in order to prolong sleeping hours.

In terms of the COVID - 19 outbreak's impact on sleep, she said available research overseas shows school closures forced by the COVID - 19 epidemic have added two hours of sleep to young students studying-gat home.

In China, some studies have revealed no marked differences in sleeping patterns of students before and after school reopened, she added.

"Given that signs of Alzheimer's disease (老年痴呆症) start to accumulate in the brain several decades before the disease begins, understanding the connection between sleep and cognition (认知) earlier in life is critical for understanding the role of sleep problems as a risk factor for the disease," said study author Yue Leng, PhD, of the University of California, San Francisco.

The study involved 526 people with an average age of 40. They were followed for 11 years. Researchers looked at participants' sleep duration and quality. Participants wore a wrist activity monitor for three continuous days on two occasions approximately one year apart to calculate their averages. Participants slept for an average of six hours. Participants also reported bedtime and wake-up time in a sleep diary and completed a sleep quality survey with scores ranging from 0 to 21. A total of 239 people reported poor sleep with a score greater than five.

Researchers also looked at sleep fragmentation (碎片化), a measure of restlessness during the sleep period expressed as a percentage. The higher the value, the more sleep is interrupted. Participants were divided into three groups based on their sleep fragmentation score. Of the 175 people with the most interrupted sleep, 44 had poor cognitive performance 10 years later, compared to 10 of the 176 people with the least interrupted sleep.

After adjusting for age, sex, race, and education, people who had the most interrupted sleep had more than twice the possibility of having poor cognitive performance when compared to those with the least interrupted sleep. There was no difference in cognitive performance at midlife for those in the middle group compared to the group with the least interrupted sleep.

However, due to the small sample size, the researchers were unable to fully investigate potential race or sex differences. "More research is needed to assess the link between sleep disturbances and cognition at different life stages and to identify if critical life periods exist when sleep is more strongly associated with cognition," Leng said.

Ma Mian Qun, also known as "Ma Mian Zhe Qun (horse face pleats (褶) skirt)", is a kind of traditional Chinese dress. The question of{#blank#}1{#/blank#}the dress is named Ma Mian Qun has always been puzzling. What's the relationship between the animal's name and the skirt? In fact, "Ma Mian" is a kind of structure {#blank#}2{#/blank#}(use) for defense in the city wall system.

But {#blank#}3{#/blank#}its name is really related to the city wall is still a question to be confirmed. All the related books only show that the smooth surface without pleats in the middle {#blank#}4{#/blank#}(call) "Ma Mian", but there is no {#blank#}5{#/blank#}(far) explanation for the source of "Ma Mian".

The Chinese Horse Face Skirt shows {#blank#}6{#/blank#}unique structural design that pairs practicality with elegance. Its form-fitting waistband transforms into an A-line shape, characterized by a series of pleats that expand outward,{#blank#}7{#/blank#} (offer) a glimpse of the wearer's grace with every step.
