why is it also called "snowballing"? It seems to be an image metaphor. After it is made, it is rolled in the yellow bean, as if the countryside is really snowballing and raising dust, hence the name. Even the predecessors questioned this point. "Yan Dou Snack Chant" said: "The brown sugar and water stuffing are arranged skillfully, and the yellow flour is buried in the dough beans. He Shiqun called' snowballing', and the name was almost humorous. " He also said: "Soybeans are sticky with rice, steamed, wrapped in brown sugar and water, rolled in fried bean noodles and sold on a plate. It's really incredible to call them' donkey rolling'." It can be seen that the name of "snowballing" has been established. Nowadays, many people only know the nickname, but don't know its proper name. At present, snack bars are available all year round, but most of them have changed from yellow wheat to Jiangmi noodles, because the color of soybean noodles is still yellow, which is a favorite snack of the masses.
