At present, the catering industry is also the most popular industry. Just look at how many Sichuan restaurants there are in China. The authentic place to learn Sichuan cuisine is Chengdu. Of course, we have to find a more formal place where many snacks are trained in Chengdu. I suggest, first look at the products, the products don't pass, and other things don't need to be discussed, so the taste is more important, and find a professional training school to study.
