The original Tan Shi Street Wholesale Market has all been transferred to Fangxin Village on the edge of the West Second Ring Road. You can take a bus to Fangxin Village Wholesale Market in the West Second Ring Road. I remember seeing it on the second floor.

As for how to open a shop, it is nothing more than determining the location of the store first, then finding the purchase channel, and then running all kinds of procedures and licenses. It's not difficult, but I think you'd better find a community with more elderly people, who prefer vegetarian food.

I wish all the best!
