Teacher Cui Puquan, a well-known Beijing folklore expert, said that the custom of eating "lazy dragons" on this day has been circulating for a long time. The so-called "lazy dragon" is a long roll of steamed dough. The method is to roll the dough thin and grow it into pieces, put the mixed meat stuffing on it, then roll it into strips, put it in a steamer, steam it and cut it, and share it with the family.
In addition, the so-called fright refers to the recovery of hibernating animals such as insects. Therefore, people should drive away pests on this day, and get rid of pests at home who just woke up.
