In the old society, people generally didn't kill white cocks easily and didn't eat their meat. At that time, the old habit was that the white cock could ward off evil spirits, and the blood of the white cock could ward off evil spirits. In the past, there was a custom in the countryside: most people would bring a white rooster to the funeral. When they arrived at the cemetery, before into the pit's coffin was buried, the Taoist priest would cut off the neck of the white rooster and let chicken blood sprinkle a few drops on the coffin lid, which meant to kill the demon.
In ancient mythology, there is also a saying that chickens are deformed birds. It is said that during the reign of Emperor Yao, friends from afar paid tribute to a bird that could ward off evil spirits. Everyone welcomes the arrival of the bird, but the tribute doesn't come every year. People carve a wooden bird, cast it in bronze and put it on the portal, or draw it on the doors and windows to scare away monsters and make them afraid to come again. Because the bird looks like a chicken, it gradually changed to draw a chicken or cut window flowers and stick them on doors and windows, which became the source of paper-cutting art in later generations. China paid special attention to chickens in ancient times and called them "birds with five virtues". "Biography of Korean Poetry" says that a crown on the head is Wende; There is a distance behind the foot to play, which is martial arts; It is brave for the enemy to dare to fight before; It is benevolence to have food to welcome the same kind; It is faith to keep vigil and break dawn. Therefore, people not only cut chickens during the Chinese New Year, but also set the first day of the New Year as Chicken Day.
