Green tea used to refer to a drink, but now it can refer to a girl: she looks pure and harmless, considerate everywhere, and speaks softly and lovely, but in fact she is deliberately interested in her boyfriend.

Judging from the recorded history, Mengding Mountain is the earliest place in the history of our country where artificial cultivation of tea is recorded. It can be proved from Tong Yue written by Wang Bao and Legend of Planting Tea Trees in Mengshan written by Wu Lizhen that Mengding Mountain in Sichuan is the origin of tea planting and tea manufacturing.

Green tea originated in Bati (now in northern Sichuan and southwestern Shaanxi). According to "Huayang Guozhi Bazhi", when the Zhou Dynasty attacked, Ba people sent tea to the army. Huayang County Records is a faithful history. It can be concluded that the Ba people in northern Sichuan (seven buddha Gongcha) began to cultivate tea artificially in the garden no later than the Western Zhou Dynasty.

The processing of green tea is simply divided into three steps: enzyme fixation, rolling and drying, among which the key is enzyme fixation. Fresh leaves are inactivated by enzyme activity, and the chemical components contained in them are basically unaffected by enzymes, and change through heat, thus forming the quality characteristics of green tea.
