Either go to a special cooking institution or go to a restaurant like Lamian Noodles as an apprentice, but as an apprentice boss, you won't easily give you the most critical recipe, and you will suffer indignities.

I suggest you promote better cooking institutions, such as pay the East, a decades-old brand. It is first-class in China. You can go to their website to check and consult again. There should be something you want.
