1, Xi Legend: Legend has it that there is an evil beast-Xi. When the mountain is closed by heavy snow, Xi will go to the neighbor's house nearby to find food. At the end of the twelfth lunar month, people have to go to the nearby bamboo forest to avoid Xi. One year, a kind mother-in-law saved a child fainted by hunger on the roadside and took it to a bamboo forest to escape the dusk. The clever boy told everyone that he had a way to get rid of the evening, so that everyone could cut more bamboo poles and take them away. After returning home, red cloth was hung outside the doors of each family. When Xi attacked again, the children came forward to attract Xi's attention and asked the villagers to throw the broken bamboo joints into the fire, but everyone froze with fear. At this moment, "Xi" picked up the child with his horn and threw it to the ground. The villagers responded to the sound of children falling to the ground and threw bamboo joints into the fire. "Xi" turned and ran away after hearing the sound, and did not destroy anything in the village again. But the clever boy who saved the village died in. Because "Xi" is not dead, firecrackers are set off every year on the 30th of the twelfth lunar month, and red cloth strips are hung in front of the door to prevent "Xi".

2, the gas wave shoots late: Legend has it that a long time ago, there was a monster named "Xi" who always spoiled beautiful girls at night and even ate them. A hunter named Qi Lang saw that people were suffering from "Xi" and took his dog everywhere to look for "Xi". It didn't appear until the night of the twelfth lunar month. Air billow released his hounds to bite him, and "Xi" fought air billow and the dog. As soon as people heard that there was a fight outside, they all picked up their things and knocked at the door loudly. "Xi" tried to escape, but she didn't know that her hind leg was bitten by a hound. Air billow took the opportunity to shoot with a bow and killed "Xi" with an arrow. Since then, people have called the 30th of the twelfth lunar month "New Year's Eve". On this night, every household should keep watch and shoot guns to drive away the ominous and welcome happiness and auspiciousness.

3. Shousui: In Archaean, there was a fierce monster called Nian, who went to crowded places to eat big living people every 365 days. The time of haunting was after dark and before the crow broke dawn. People came up with a complete idea. Every night, they prepare dinner in advance, turn off the fire, clean the stove, tie up all the chicken coops and cowsheds, and seal the front and rear doors of the house. Hiding in the house to eat "New Year's Eve", this dinner has ominous meaning, and it is very rich. The whole family gathered for dinner to show harmony and reunion. Before eating, they must make sacrifices to their ancestors and pray for their gods to bless them to spend the night safely. After dinner, no one dared to sleep, so they sat together and chatted with courage. Gradually formed the habit of not sleeping on New Year's Eve.
