The law of tea production in the world is red in the south and green in the north, that is, only high quality black tea can be produced in lower latitudes (such as India and Kenya), while high quality green tea can be produced in relatively high latitudes (25  degree~ 30  degreenorth latitude). The international price of green tea has always been higher than that of black tea. The quality of green tea in India, Indonesia and Sri Lanka, the main tea producing countries, is not high. Since the 1970s, the above three countries began to change red to green in an attempt to occupy the international green tea market, all of which ended in failure. China's famous green tea is mainly distributed in mountainous areas. with rich rural labor resources and low labor costs, the development of green tea industry has obvious comparative advantages.
