Tomb-Sweeping Day, a Shanghainese, has a reunion dinner?

Shanghainese had the custom of eating Youth League before and after Tomb-Sweeping Day, which can be traced back to the Zhou Dynasty more than 2,000 years ago. According to "Zhou Li", there is a law that "Muduo is forbidden to burn in the fire in mid-spring", so people put out cooking and "eat cold food for three days". The cold food period, that is, one or two days before the name is unknown, is also designated as the "Cold Day".

The traditional foods of the ancient Cold Food Festival include glutinous rice cheese, wheat cheese, almond cheese, etc. You can prepare for the Cold Food Festival in advance, and you don't need to make a fire to cook.

There is also a kind of "polished rice" in the traditional food of the cold festival. According to trivial records: "Shu entered the Cold Food Festival, picked Erythrina leaves, and dyed rice with fine holly, which was green and shiny." The Seven Courses in the Ming Dynasty also said: "The ancients used Erythrina leaves as cold food and dyed rice blue as a sacrifice. Ziyang was angry, too, and now it has become a green and white jiaozi. That's what it means. " In the Qing Dynasty, Lu gave a clearer explanation to Youth League: "Youth League cooked lotus roots are sold in the market, and it is ok to eat them cold."
