Tofu is a traditional folk food. Every household buys some tofu during the Spring Festival, which means "all are blessings". However, tofu is not suitable for making New Year's Eve, because tofu is also the main course of folk "white banquet", so the "white banquet" in some places is also called "tofu banquet", which is obviously inconsistent with the happy and peaceful atmosphere of New Year's Eve, so don't eat tofu on New Year's Eve and save it for next time.
