What is a box to eat on the third day of New Year's Day?

Eating a box lunch on the third day of New Year's Eve means reunion. There is a folk saying that "jiaozi in the first day, noodles in the second day, and boxes in the third day turn home", which shows that there is a custom of eating boxes in the third day. Box lunch is a kind of pasta, which is more popular in northern China.

The custom of burning door-keeper paper on the third day of New Year's Eve: On the third day of the old day, the pine and cypress branches on the first day of the New Year and the door-keeper stationery hung on the first day of the New Year are burned together to show that the New Year has passed and it is time to start business again. As the saying goes, "if you burn the janitor's paper, one will seek physiology." (Note: Folklore, please don't be superstitious. )
