Of course, we have to find a more formal place in Chengdu where many snacks are for training. 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. The products don't pass the test, but the taste is more important. We should find a professional training school to study. I suggest you find several local famous snack training institutions online. Before signing up, remember to give it a try offline, make an inspection, compare and choose the best one you think. Don't be deceived by greed and cheapness. 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.
