[0002] Tea, commonly known as tea, generally includes the leaves and buds of the tea tree. Other names include tea, tea, tea, tea. Tea ingredients include catechins, cholesterin, caffeine, inositol, folic acid, and pantothenic acid, which are good for health. Tea beverages made from tea are one of the three major beverages in the world. Tea originated in China, and tea was first used as a sacrifice. However, it has been used as a vegetable since the late Spring and Autumn Period, and developed into a medicinal beverage in the middle of the Western Han Dynasty. It was not until the late Western Han Dynasty that it developed into a high-end court beverage. It was not until the Western Jin Dynasty that it became popular among the people as an ordinary beverage. The earliest remains of artificial tea cultivation were found in the Tianluoshan site in Yuyao, Zhejiang, which has a history of more than 6,000 years. Tea drinking began in China. The leaves are leathery, oblong or oval, and can be directly brewed with boiling water. They are divided into six categories according to the variety, production method and product appearance. According to the season of harvesting, it can be divided into spring tea, summer tea, autumn tea and winter tea. Reprocessed tea is made from various raw teas or refined teas, including scented tea, compressed tea, extracted tea, medicinal and health tea, tea food, tea-containing beverages, etc.
