Of course, we have to find a more formal place, where many snacks in Chengdu are practiced. At present, the catering industry is also the hottest industry. Just look at how many Sichuan restaurants there are in China. The place to learn authentic Sichuan cuisine is Chengdu. I suggest that we look at the products first, but the products don't pass, and the other things don't need to be discussed. The taste is more important, so we should find a professional training school to study. Generally, regular snack training institutions are ok, but each snack training institution teaches different tastes. I suggest you find several famous local snack training institutions online, and remember to try offline before signing up. Just compare and choose what you think is the best, and don't be cheated for petty gain. The emphasis is on teaching mode, and there are not many practical courses. Technical schools focus on more hands-on practice and theoretical knowledge. If you only talk about theoretical knowledge every day, you will learn nothing. It is best to combine practice with theory. It's best to go on a field trip and get to know more.
