Background Art

Tea refers to the leaves of the evergreen shrub tea tree that can be used to make tea, as well as beverages made from these leaves. Tea contains theophylline, cholestenone, caffeine, inositol, folic acid, pantothenic acid and other ingredients that can improve human health. Tea drinks are known as "one of the three major beverages in the world." Tea is a traditional Chinese drink that can both maintain health and prevent diseases, and is deeply loved by consumers. In the tea refining process, tea leaves need to be screened.
