In 2022, most of the offline catering industry was seriously damaged by the epidemic, and the catering industry could only be forced to close down most of the time. Coupled with the cost of living and high rent in Shanghai, selling pancake fruit in Shanghai in 2022 will not make money.

Pancake fruit is a famous snack in Tianjin, China, and Tianjin people take it as breakfast. Pancake crust consists of mung bean pancake, egg, fried dough sticks or crust, with batter, chopped green onion, fermented bean curd and Chili sauce as seasoning.
