It doesn't cost money. If you want to open your own shop and sell it yourself, go to a hotel and come back for an internship in January. The spicy crayfish in Guijie, Beijing is famous, and the cost is estimated to be around 3,000 yuan. I also have a set of skills here, free of charge, but I don't know if I can achieve the effect you want. I'm also a chef. I just want to learn to ask questions. It's absolutely free. I'll give the answer when I have time.
