The name of cinnabar comes from cinnabar, which is a red pigment in China traditional art, so it is called cinnabar. China seal is printed with cinnabar paste, and cinnabar pigment is also used in China scarlet paint. In Taoist culture, cinnabar is regarded as life and eternal color. Because cinnabar is a positive color, it is often used for the emperor's royal approval and the decoration of palace walls. Officials' families and local rich people often paint their doors with cinnabar. The walls of the Forbidden City are scarlet, but now people think that scarlet is scarlet, which should be influenced by Manchu foreign culture.
