Why can't the white cock be given away?

The main function of white cock in folk custom: to ward off evil spirits

In the past, 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 rural areas: most people took a white rooster to the funeral. When they arrived at the cemetery, before into the pit's coffin was buried, the Taoist would cut off the neck of the white rooster and let chicken blood sprinkle a few drops on the lid of the coffin, which meant killing the devil.

In ancient mythology, there is also a saying that a chicken is a deformed bird. It is said that during the reign of Emperor Yao, friends from far away 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 paint 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. In ancient China, chickens were particularly valued and were called "birds with five virtues". Han Shi Zhuan says that it has a crown on its head and is a virtue; There is a distance behind the feet to fight, which is martial arts; It is brave for the enemy to dare to fight before; There is food to greet the same kind is benevolence; It is a belief not to lose time and the dawn at 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.
