According to Shuowen written by Xu Shen in the Eastern Han Dynasty: "The sheep are auspicious." Because "sheep" and "auspicious" are synonyms, and "auspicious sheep" means "auspicious", people used to carve the auspicious words of "Daji sheep" on utensils at that time, and match them with the image of sheep, so as to make life auspicious and all the best.
At that time, people not only wanted to be lucky in life, but also carved the inscription of "auspicious sheep" and sheep-shaped patterns on daily bronzes. For the sake of peace after death, they also put the image of the sheep's head in the center of the door when building the tomb. For example, at the tomb gate of Shaogou Han mural tomb in Luoyang, Henan Province, a sheep's head is shaped opposite, and a pair of big horns are rolled down around, and the composition is regular; The lower side of the sheep's head is painted with a mural of a god tiger eating a woman, in order to achieve peace and exorcism.
