The magic mirror is one of the Taoist implements. Taoism set up a magic mirror on the altar of sacrifice and hung it right above the altar shrine. It believes that the magic mirror can reflect the true shape of ghosts, so that they can't get close to the altar and dare not enter the palace. Ge Hong in the Eastern Jin Dynasty recorded in Bao Puzi's Inner Chapter that Taoist priests who entered the mountains in ancient times "hung behind their backs with nine-inch mirrors, so the old spirits dared not approach." Taoism believes that the mirror can see everything and show the original shape of the deformed monster. When The Journey to the West, a ghost novel in the Ming Dynasty, captured the Monkey King, the Monkey King could not escape because he used a magic mirror. The sixth story of Journey to the West, "Guanyin went to the meeting and asked her why, and the little saint surrendered to the great sage", contains: Li Tianwang and Nezha stood in the air with magic mirrors in their hands, covering the Monkey King in the middle, and fighting one after another. "Romance of the Gods" King Li Jing of Tota offered a magic weapon to look at the demon mirror, which broke the evil spirit around Lion Camel Mountain and gave him a panoramic view. The Romance of the Gods also shows Jiang Ziya's acting skills with a magic mirror, which can reflect the true colors of monsters. Li Shangyin, a poet in the Tang Dynasty, wrote a poem entitled "I smell the magic mirror, and I am at the sword front". Taoist magic mirror, sword, seal, coffin and spiritual map are the basic means of practicing the law. Demon mirror was widely used in ancient times. People hung it on the wall opposite their front door, thinking that it could exorcise evil spirits and keep ghosts safe. At present, there is a bronze mirror of the Ming Dynasty in the East Room of the main hall of Mount Tai Tiangong.
