According to historical records, in order to solve soldiers' anorexia, a general in Ma Wu had a whim. Take the donkey as an example. When it is still, it rolls on the spot and is covered with yellow meat. He steamed the yellow wheat that everyone ate every day into red bean stuffing and rolled it up with fried bean powder, which not only cured everyone's anorexia, but also was loved by the world and spread to this day.

2. Significance

Rolling on a donkey, also known as bean flour cake, is one of the ancient snacks in Beijing. Its main raw material is yellow wheat, and the soybeans spilled in the final production process are like the bursts of loess raised by wild donkeys in the suburbs of old Beijing, hence the name "snowballing donkey".

According to the custom of old Beijing, people always like to buy "snowballing usury" in February of the lunar calendar to taste it.

However, although snowballing usury is delicious and has good nutritional value, don't eat too much, because it contains too much sugar, which will lead to excess energy and easy blood sugar rise. In addition, it is not easy to digest soft waxy ingredients if they are ingested too much. Therefore, as a traditional food, snowballing usury can be tasted in festivals and has endless aftertaste.
