Feeding meatballs in February means that the earth recovers and the yang rises after the sting. As the saying goes, "A hundred bugs kill you." During the Dragon Festival, many activities to drive away drugs are very popular among the people. People eat snowballing usury, which means "when a pest dies, people turn over". Maruko means snowballing.

Bowling is a kind of bean flour cake, a Muslim snack in Beijing. Knead steamed yellow rice (or glutinous rice) into a ball, sprinkle with fried soybeans, add red bean stuffing, roll into strips, sprinkle with sesame seeds, osmanthus fragrans and sugar. Because the food stalls in the Qing Dynasty were made and sold now, the bean noodles were sprinkled as they were made, just like the donkeys in the country rolling on the spot, covered with loess, so they got the name of humor.
