If you want to join, I'd better give you some advice. If you have friends, you'd better go to the local area to study better. It's not difficult, as long as someone is willing to teach you. I just worked in Chongqing, learned the technology from my friends, and went home to open a hot and sour powder shop. Compared with some so-called franchise stores in our city, my family's taste is more authentic, and if I join, I heard that I will pay a part of the franchise fee first, and then I will take the materials you use here from it, which means that he not only earns your franchise fee, but also earns your raw material fee, which is much more expensive than getting goods locally, so joining is generally to work for him.
