Dragon, dragon, fish, mirage. The four disguises are unicorns, and the four disguises are elks. Because the head of the unicorn looks like a dragon, but there is a horn on it. Because the neck of the unicorn looks like a dragon, but there are colorful manes on it. Because Kirin's body looks like a fish, but it has strong limbs. Because the Kirin's waist and abdomen appear mirage, but there is no fatal scale under its abdomen. Therefore, it is named Sibuxiang.
Each appearance of the unicorn will be a very special period. It is recorded that Confucius is closely related to the unicorn. It is said that the unicorn appeared before Confucius was born and died. It is said that before Confucius was born, a unicorn "spit jade script" in his yard. The book wrote that "the son of water essence is the king who died during the decline of the Zhou Dynasty". In the spring of the 14th year of Duke Ai in the Spring and Autumn Annals, Confucius mentioned that "Xishou got the unicorn", which made Confucius cry, And said, "My way is poor.". Confucius once wrote a song: "When Lin and Feng traveled in the Yushi of Tang Dynasty, why not come now? Lin and Lin worried me." Confucius died soon, so it was also regarded as a symbol of Confucianism.
