Do Hakkas have to make tofu on New Year's Eve? Why?

Sufu is a traditional dish in China, belonging to Hakka cuisine. It is said that this dish originated from jiaozi in the Central Plains. Because there is little wheat in the south, Hakkas put their feelings on Jiaozi culture in the north and Central Plains culture with fermented bean curd. Every Spring Festival, other festivals, or leisure time, we always make a steaming dish of fermented tofu, which is the favorite of Hakka people and has a long reputation.
