Catering is really never out of date. I've always been a caterer, and I've done mala Tang in noodle restaurants. However, if you want to be simple and easy to use, it is also possible to open a dumpling restaurant. I have a shop in jiaozi. Dumpling skin is made by machine, so it doesn't need to be rolled by hand. The operation of jiaozi Store was specially studied in Niu's jiaozi Store. As long as there is a common mother stuffing formula, the stuffing can be completed in a few minutes.
