What does it mean to be ugly?

There is a branch of 12. There are many divinatory rules in the prediction of six hexagrams in Zhouyi, such as combination, birth, collision, etc., in order to analyze and judge the information contained in the divinatory symbols, find out some specific situations of the things to be predicted, and make people choose the right method and opportunity to solve things well, avoid detours, avoid the interference of unfavorable situations, and make people pursue good fortune and avoid evil, and move in the right direction. Unity and ugliness are two branches of earthly branch. When they meet together, they have several meanings. One is that oneness can enter the ugly grave; The other is that ugliness can give birth to oneness; The third is the combination of ugliness and unity (the three branches have combined unity and ugliness into three); And the fourth is that oneness can make a fool of yourself in the library.
