What is the current situation and prospect of China herbal tea market? Is it possible for college students to start a business here?

It should be said that the northern market has great prospects because it is blank. That year, I made a plan and made an investigation. The store began to sell badly. Although the north is empty, we must find a good location and entry point, otherwise it will be the same. In the south, the competition is too fierce to make a market. At the same time, herbal tea is very profitable in the northern market.
