According to Lu Yu's Tea Classic in the Tang Dynasty, "Tea is a drink, which originated in Shennong". In other words, as early as 4000 years ago, the ancestors of the Chinese nation began to use tea as a drink. Although the invention of tea by Shennong may be just a legend, it is an indisputable fact that people in China have a long history of drinking tea. At least in the Qin and Han Dynasties more than two thousand years ago, tea has become an important part of China people's daily life.

China is the hometown of tea. In the long history of dealing with tea, a rich and unique tea culture has been formed. Nowadays, drinking tea is closely related to the material life and spiritual life of China people. Drinking tea has not only become a life custom of China people, but also has been deeply integrated into the spiritual temperament of China people. Therefore, it is natural for everyone in China to know a certain tea culture, especially for those who pursue richer life interests and deeper spiritual enjoyment.

China tea culture is extensive and profound, and tea tasting, making tea and tasting tea are several aspects. When you step into the door of China tea culture, you will begin this fascinating tea culture tour full of freshness and surprise. The origin of tea trees in China is the birthplace of tea culture. Different from the present situation that tea trees are mainly cultivated artificially, the original tea trees are all wild, and China is the country with the earliest and most wild tea trees found. As early as the Three Kingdoms period, it was recorded in Wupu Materia Medica: "There are melons and reeds in the south, which are as bitter as tea, and you can also drink them without sleeping." The "bitter gourd" here refers to the wild big tea tree. This shows that there were wild tea trees in China more than 1700 years ago. Wild tea plants are widely distributed in China. According to incomplete statistics, wild tea trees were found in 198 locations in 10 provinces, especially in southern and western Yunnan, southern Sichuan and Guizhou Province. In addition, the size of wild tea trees in China is rare in the world. For example, in Yunnan Province, there are more than a dozen wild tea trees with trunk diameters above 100 cm, among which Longtan tea tree in Pu 'er area is 18 high. 5 meters, the diameter of the trunk at the base reaches 143. 5 cm, and the diameter of the trunk at the base of Shimen tea tree in Jingdong County is 83. 4 cm, the tree is 25 meters high, which is the highest in the world.

There are many kinds of tea in China, which can be basically divided into six categories: green tea, white tea, yellow tea, black tea and black tea. Pu 'er tea is classified as black tea. Pu 'er tea is one of the top ten famous teas in China. It is said that in the Eastern Han Dynasty, there was a folk saying of "Zhu Gekongming", which led to the legend that Pu 'er tea was cultivated and utilized for at least 1700 years. Up to now, many ethnic minorities still regard Zhu Gekongming as the ancestor of tea, and are convinced that it is a fact to plant tea trees in Wuhou, which has been passed down from generation to generation.

Pu 'er tea is named because its origin belongs to Pu 'er Prefecture (now Pu 'er City) in Yunnan. Pu 'er tea is a famous local tea unique to Yunnan. It is loose tea and pressed tea made of sun-dried green hairy tea with big leaves. Its appearance is thick and plump, its color is brownish red, its internal soup is red and bright, and its aroma is unique and fragrant. It has the effects of losing weight, beautifying, lowering blood sugar, lowering blood fat and warming stomach. Pu 'er tea can be divided into raw tea and cooked tea. Raw tea is fermented by spontaneous combustion. Using fresh leaves of Yunnan big-leaf tea tree as raw materials, pressed tea was made by processes such as enzyme fixation, rolling, sun drying and autoclaving. It is characterized by dark green appearance, pure and lasting fragrance, thick and sweet leaves, clear green soup color and thick yellow-green leaves. Cooked tea is artificially ripened. It is made of Yunnan big-leaf sun-dried green tea, which is processed by post-fermentation to form loose tea and pressed tea. It is characterized by reddish brown appearance, bright red soup color and old fragrance. Pu 'er tea is different from other teas because it is new and old. "The older you get, the more fragrant you get" is recognized as the biggest feature that distinguishes Pu 'er tea from other teas.

Pu 'er tea is the most cultural one among all kinds of teas. Besides its historical inheritance, processing art, tasting and brewing with other tea products, we can fully understand the local customs, concepts and civilizations at that time from the aspects of basic paper printing, paper quality, tea material, exquisite suppression and packaging of tea products. Pu 'er tea is a wonderful flower in China tea garden.
