Tail tooth is a traditional folk festival in Fujian, the "end" of merchants' one-year activities and the "first sound" of ordinary people's Spring Festival activities. The second and sixteenth day of each month is the day when Minnan businessmen worship the land god, which is called "making teeth". February 2 is the first tooth-making, called "the first tooth"; The dentist on December 16th was the last dentist, so it was called "tail tooth".

The origin of tail teeth:

December 16th of the lunar calendar is the last sacrificial activity in a year, commonly known as "Tail Teeth". In ancient times, there was a poem, "A man pays a glass of wine a year, and every family thanks the earth with cigarettes." This is the scene of the tail teeth described by the old poets. The "glass of wine" in the Shanglian refers to the allusion of Song Taizu's "glass of wine to relieve the soldiers" that the owner wants to dismiss the man; The second couplet is the tail tooth season, and every household is offering sacrifices to the landowner. After the folk worshiped the birthday of the Land Lord on the second day of February, the owner immediately gave a banquet to the employees. On the day of "Tail Teeth" on December 16th, in order to thank the Land Lord for his care for one year, the merchants would prepare rich sacrifices to reward the Land Lord, and the employees would be rewarded after the worship.

In the early days, the general merchants or factories used the meal of "eating tail teeth" to imply that they wanted to fire their employees or workers. However, people in the old days were more kind, if it weren't for the guys, it wouldn't work, or the business management of the owner was not good. You don't just dismiss a guy, and the way to dismiss him is not to send a dismissal notice or severance, but to hint at the tail tooth banquet and tell the employee that he is fired.
