    Thang-ga is a special kind of painting. It started from the Tang Dynasty. Thang-ga paintings have attracted the public's attention in recent years. At the same time, the Chinese government has also tried hard to protect the culture.

    Thang-ga paintings were developed in the 7th century in the Tibetan area. The paintings are colourful and the paints used in Thang-ga paintings are different from those in other paintings. Because of the special environment of the Tibetan Plateau (高原) and the excellent painting skills, the colours of Thang-ga paintings look special. The paints in Thang-ga paintings in the past were made from minerals, including gold, silver, as well as some plants. Since they were made by hand, the beautiful colours could last for hundreds of years.

    However, with the development of machines, people now use cheaper and more easily-made chemicals to make paints. The traditional paints in Thang-ga paintings needed too much work and there were many secret methods. Later people stopped making the paints and forgot about them. So the skills were almost lost.

    Cars make our lives more convenient. But they can also be a problem. For example, fossil fuel (化石燃料) cars mainly cause air pollution.

    To improve the environment, many countries are developing electric vehicles (EVs,电动车). Among them, China is taking a leading role and has created the world's largest EV market.

    Last year, over 40 per cent of the 753,000 EVs sold in the world were sold in China, more than twice as many as the number sold in the United States.

    "Filling up a fossil fuel car with gas (汽油) is more expensive than charging (充电) an electric car," said Wu Hao, who bought an electric car this year.

    However, there are still some problems. It can be hard to find charging piles (充电桩) and the cars can't go far before being recharged.

    Some of these problems are being solved. In 2014, China had 31,000 charging piles. Now China has the world's largest EV charging network, with more than 450,000 charging piles in total.

    Developing EVs is one of many efforts that China has made to cut down pressure on its environment after the government promised to stop increases in carbon dioxide emissions (二氧化碳排放量) by 2030.

    "As China goes, so will the world's car industry," the Wall Street Journal said.

    Speak clearly and slowly. But do not shout at others even if they don't understand you. {#blank#}4{#/blank#} Instead, it can be seen as a rude behavior. What's more, even if there are difficulties in communicating with people from other cultures, do not treat other people as though they are stupid.

    {#blank#}5{#/blank#} In some cultures, looking another person in the eye when you speak is seen as a sign of honesty and interest. However, in other cultures, it may be disrespectful.

    English playwright Arthur Wing Pinero said, "Where there's tea, there's hope." Similarly, a Chinese saying goes that "Firewood, rice, cooking oil, salt, sauce, vinegar and tea are the seven necessities to begin a day."

    Tea is, without doubt, welcomed all over the world. According to Statista, a German website for statistics (数据), global tea production reached about 5.8 million tons in 2018. It has become the most consumed beverage (饮品) in the world – after water, of course.

    According to the UN, tea is much more than just a hot drink. It's a big part of many cultures around the world. You probably know that people in China use top-grade tea to show respect when receiving important guests. Meanwhile, the British tradition of afternoon tea is an important part of that country's identity. Making Malaysia's pulled tea has become a sort of art form, where drinkers take pride in its entertainment aspects.

    Apart from its cultural significance (意义), tea is also a medicine, used from ancient times to modern day. "Tea is cold and lowers the fire," Chinese Ming Dynasty herbalist Li Shizhen once said. The health benefits of tea are still being discovered today: preventing heart disease, obesity and cancer have all been linked to drinking green tea, according to the National Center for Biotechnology Information in the US.

    Hot or cold, bagged or loose-leaf, tea is more than a drink – it's a social custom and also a magic medicine, a link to the past and a way of life.
