Tea has not yet become a futures variety, but if we look at the futures varieties owned by several exchanges, there are some influencing factors in the domestic price trend of commodity futures, such as seasonal factors, supply and demand, national policies, international markets, etc., so that the trade of such varieties will be more active, and Zhengzhou Stock Exchange will soon launch thermal coal. However, China people prefer to regard tea as a commodity, but there is no market in the world. Its price can't interact with the outside market, and the price will definitely not be the mainstream. Becoming a futures commodity requires various investigations, and I don't think tea is ready yet.
