There are four seasons for drinking tea, generally speaking, spring tea, summer green tea and autumn green tea, and black tea in winter. One is the consciousness of drinking scented tea in spring, green tea in summer, green tea and black tea in autumn and black tea in winter. This way of drinking tea is healthy. Tea making is divided into four stages: tea before tomorrow, tea before rain, summer tea and autumn tea. Qian Ming tea belongs to the top grade, which contains many vitamins and organic substances. Because of the low yield, Qianming tea is relatively expensive. In the tea-making industry, there is a saying that spring tea is soft, summer tea is astringent, and autumn tea is mellow, so it is hard to pick. In other words, picking more autumn tea will affect the quality and yield of spring tea next year.
