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. The products don't pass the test, but the taste is more important. We should find a professional training school to study. It is suggested that when choosing a school, it is best to go to the field to see the environment, facilities and teachers' level of the school. To learn technology, the hardware facilities of the school must be excellent. Only with more operations, practice makes perfect, and natural technology can be learned. 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, and you will know better yourself.
