As the saying goes, "Seven things to do when opening the door are firewood, rice, oil, salt, soy sauce, vinegar and tea." Tea is one of the most common and common drinks in Chinese daily life. Drinking tea is life and culture. On the evening of November 29, Beijing time, the "Chinese traditional tea making techniques and related customs" declared by China passed the review at the 17th ordinary session of the Intergovernmental Committee for the Protection of Intangible Cultural Heritage of UNESCO held in Rabat, Morocco, and was included in the UNESCO Representative List of Intangible Cultural Heritage of Humans. So far, China has 43 projects listed in the UNESCO Intangible Cultural Heritage List, ranking first in the world. China is the first country in the world to plant tea trees and make tea. "China is the first country in the world to plant tea trees and make tea, and tea culture is deeply integrated into Chinese life." Wang Chenyang, director of the Department of Intangible Cultural Heritage of the Ministry of Culture and Tourism, said. Thousands of years ago, the Chinese began to pick, make and drink tea. In the late 8th century, Lu Yu wrote the Book of Tea, which was the first monograph in China to systematically explain tea knowledge and practice. "Tea is the Jiamu of the south." In China, hundreds of tea trees are distributed in the four major tea regions of Jiangnan, Jiangbei, Southwest and South China, south of the Huaihe River in the Qinling Mountains and east of the Qinghai Tibet Plateau. Through long-term practice, relevant communities, groups and individuals have developed more than 2000 kinds of reprocessed tea, including green tea, yellow tea, black tea, white tea, oolong tea, black tea and scented tea, based on local customs and different skills. "The tea is for civilian use, which is equal to rice salt, which cannot be dispensed with in a day." For people all over China, tea is a necessity, and they have different needs for tea. For example, Jiangsu and Zhejiang like green tea, while Fujian and Taiwan like oolong tea. In Tibet, Qinghai, Xinjiang, Inner Mongolia and other places, people are used to making butter tea and milk tea with black tea. "The rain returns to the heating when it is half sunny, and the light thunder has just begun to sprout." In March and April every year, when spring returns to the earth, tea trees sprout, which is also the busiest time for tea makers. They use the hand skills handed down from generation to generation to make tea products of various flavors for people to drink and share, thus forming different tea making skills and related customs. For example, if guests visit, they should serve tea; The newlyweds will serve tea to their parents at the wedding; Tea tasting and tea fighting among tea friends; Tea farmers should offer sacrifices to tea gods. A relatively complete inheritance system has been formed. China's tea culture has been passed on from generation to generation. A systematic and complete knowledge system, extensive and in-depth social practice, mature and developed traditional skills, and a rich variety of handicrafts have been formed. Not only that, "Chinese tea" has also formed a relatively perfect inheritance system, which is an important prerequisite for inclusion in the list of representative works of human intangible cultural heritage. It is understood that the relevant knowledge and skills of "Chinese tea" are mainly inherited through families, apprentices, communities and other traditional ways, and have been integrated with formal education. For example, in terms of family inheritance, the production skills of Anxi Tieguanyin have been passed on to the 13th generation of the Wang family in Anxi County, Fujian Province. In terms of the inheritance of teachers and apprentices, Jingshan Tea Banquet has been inherited in Jingshan Wanshou Temple, Yuhang District, Hangzhou City, Zhejiang Province since the first year of Tianbao in the Tang Dynasty (742 AD). It was passed on by the abbot to his successor, and has now been passed on to the 121st generation; Anhui Qimen Black Tea Making Techniques
