Why is it called "snowballing"? It seems to be an image metaphor. After it is made, it rolls in soybeans, as if the country really snowballs and raises dust, hence the name. Even the predecessors questioned this. "Yan Dou Snacks Ode" said: "Brown sugar and water stuffing are skillfully arranged, and yellow flour is buried in flour beans. He Shiqun is called' Snowball' and his name is almost humorous. " He also said: "Soybeans and rice are glued together, steamed, wrapped in brown sugar and water, rolled in fried bean noodles and sold on plates. It's incredible to call them' donkey roll'. " It can be seen that the name of "snowballing" has been established. Nowadays, many people only know the nickname, not its real name. Nowadays, there are snack bars all year round, but most of them have changed from yellow wheat to glutinous rice noodles, because yellow bean is still yellow in color and is a favorite snack of the masses.
