China is the first country in the world to discover and utilize tea trees. In the ancient literature of China, tea tree is known as "the best of Nanmu". There are many names about tea in ancient historical materials, and the shape, sound and meaning of the word "tea" are also determined by China. The evolution and determination of the word "tea" also tells people from one side that the motherland of tea is China. Tea has become synonymous with people all over the world.

Tea trees were first discovered in China, first used in China and first cultivated in China. The southwest of China is the origin of tea trees. Ancient written records show that our ancestors began to cultivate and utilize tea trees 3000 years ago, and Yunnan has the oldest wild ancient tea trees in the world. The origin of tea must be much earlier.

Tea has a long history in China, and cultural relics related to tea culture are very rich. There are tea people, tea sets, tea books, tea paintings, water springs and related tea culture sites all over the country. China's tea culture and tea-drinking customs spread to the surrounding areas of China during the Han, Tang and Song Dynasties, and even spread to Europe and America after the Ming and Qing Dynasties, which had a great influence. All these prove that China is the birthplace of tea and tea culture, and China is the hometown of tea.

According to documents, tea was produced in the southwest of China more than 3000 years ago. The Records of Huayang Country in Changqu of Jin Dynasty is the earliest record of tea production in China. It is believed that "Nan 'an (now Leshan, Sichuan) and Wuyang (now Pengshan, Sichuan) all produce famous tea." Zhou Wuwang cut Zhou, which was really the teacher of Bashu ... He planted grain in the soil and sacrificed six animals. Mulberry, silkworm, hemp, rice, fish, salt, copper, iron, Dan, lacquer, tea and honey all have tributes. Gu, a scholar in Qing Dynasty, made a textual research in Records of the Day: "After Qin people took Shu, they only drank tea". It is understood that the earliest tea drinkers were also in the southwest of China. As early as the 1920s, Wu Juenong, a contemporary "Cha Sheng", proved that southwest China is the origin of tea trees in the world, and refuted the erroneous statement that the origin of tea is not in China. The natural conditions in southwest China are very suitable for the growth of tea trees. According to the scientific investigation in recent years, Yunnan, Guizhou and Sichuan in China are the earliest areas where wild tea trees were discovered, and they are also the largest and most concentrated areas at present. Both literature and empirical evidence prove that southwest China is the origin of tea trees in the world.
