In addition, there is a saying that "putting buns" is a specific name, which also refers to an action, that is, putting ingredients in buns, such as putting meat in buns, called meat buns, and putting vegetables in buns, called vegetable buns. In reality, there are snacks such as steamed buns, but they are also called vegetable steamed buns. Up to now, only the name of the stuffed bun has not changed.
