I want to make a window in the school cafeteria. What is this snack suitable for and where to learn it? Please recommend it. Thank you.

As a window of the canteen, the biggest problem is that there can't be repeated snack items, and the biggest feature is that it must be served quickly. It's hot now, such as Moon steamed buns, Xi 'an steamed buns, Shanghai burritos and Regan Noodles cold rice noodles, all of which are very good. Youyouxiang Snack School teaches these snack techniques, and the teacher is also very responsible.
