Tea is an excellent drink beneficial to human health. More than half of the people in the world like to drink tea. Tea is regarded as a healthy drink because it contains a lot of beneficial substances, such as theanine, tea tannin, aromatic oil, vitamin C, etc. Therefore, tea can refresh the mind, improve thinking, improve eyesight, eliminate fire and digestion, relieve summer heat, relax bowels and diuresis. Especially now, tea has three functions that other drinks can't do, namely, cancer prevention, cardiovascular disease prevention and radiation hazard prevention. In particular, green tea contains more tea polyphenols, which will combine with carcinogens after being absorbed by the human body, decompose them, reduce their carcinogenic activity, and thus inhibit the growth of cancer cells. Chemical analysis and clinical trials show that the effective components contained in green tea can slow down the reproduction of leukemia virus and human immunodeficiency virus (AIDS). Experts believe that green tea is the most effective natural antidote for cancer, and tannic acid in green tea can prevent cancer cells from adhering to healthy cells, thus reducing the spread of cancer. Therefore, drinking tea is loved by more and more people.

Distilled water and deionized water. Different dissolved substances in various water have great influence on the quality of tea soup.

Autumn rain is usually the best. Meiyu is the second, and thunderstorm is the worst.
