China has a very long history. It has many great traditional skills that have a wide influence (影响). Here we mainly talk about kites.

    The earliest mention of a kite in ancient China dates back to the 5th century BC. It was made of wood and used as a rescue signal (求救信号).

    At the time between 770 and 221 BC, Chinese kites were actually called "muyuan". They were first invented in Shandong Province for military purposes (军事目的). The kites were used to send important messages during the Chu-Han War. During the Tang Dynasty, kites were made of lighter materials, such as bamboo, silk and paper. At that time, people began to fly kites for other purposes. It was believed that letting go of the kite could remove bad luck and illness.

    Today, kite-flying is an interesting and healthy activity in China. There are large kite-flying festivals held throughout the country, and kite makers can show off their skills during the festivals.

    Red, green, blue, black and white are basic(基本的) colours.

    The world is colourful(多彩的). The sea is blue. The grass is green. Most countries in the world like green because it's a symbol(象征) of life(生命)，but people from England and Japan don't like it. Red is a popular(流行的) colour in China, but in Thailand(泰国)，it is bad to write names in red ink(墨水). It means someone is dead(死亡的). In Australia, people think the black cat can bring them good luck, but in America, people think the white cat is a lucky cat.

There's no doubt that the earth is our shared home. 

I firmly believe that only with our joint efforts can we make our environment better and better. Let's take action from now on.

①The traditional Chinese lunar calendar divides a year into twenty- four solar terms. Start of winter, Lidong in Chinese, the 19th solar term of the year, falls on November 7th this year.

②Lidong was once a big day in ancient(古代的) China. Before the day, the emperor(帝王) would take a shower and have no meat. On that day, the emperor and his officials(官员) would all dress in black and go out of the city to welcome winter. Today, to welcome the day, some people choose to have swimming competitions in the rivers in some cold places such as Harbin in Heilongjiang Province.

③As winter comes, the weather gets colder and colder. Chinese people often eat enough food to keep their bodies warm and healthy. On the day of Lidong, people in North China love eating dumplings. In South China, people love to eat chicken, duck and fish. In some places in Guangdong Province, people eat sugar cane(甘蔗) on the day. They think this is good for their teeth. In Nanjing, Jiangsu Province, people will eat green onions for good health. In Taiwan Province, people often eat mutton.

④Lidong is the time to start wearing warm clothes. In old times, the emperor would hand out warm winter clothes to the officials on the day. People would also remember to give" clothes" to their lost family. They would also have delicious food to show how much they missed the lost ones.
