At present, the catering industry is also the most popular industry. Just look at the number of Sichuan restaurants in China. The authentic place to learn Sichuan cuisine is Chengdu. Generally, regular snack training institutions are ok, but the taste taught by each snack training institution is different. I suggest you look for several local famous snack training institutions online, and remember to try and inspect offline before signing up. Just compare and choose the one you think is the best, and don't be cheated for petty gain. The focus is on teaching mode, and there are not many practical courses. The technical school focuses on more hands-on practice and theoretical knowledge. If you only talk about theoretical knowledge every day, you can't learn anything. The best thing is to combine practice with theory. It is best to go on a field trip and learn more.
