In the mnemonic of the twelve zodiac animals' conflicts, there is a saying "Sheep and Rat meet once will end," which means that the zodiac sheep and rat are in conflict and not beneficial when together. The flow of the five elements should be harmonious, and yin and yang should be balanced for peace and stability. The essence of the conflict between sheep and rats is the clash of yin-yang and five elements, that is, the rat (water) and the sheep (earth) are in conflict, causing the flow to be blocked and the family fortune to be poor.
It is an ancient saying about the incompatibility of men and women in marriage.
In ancient times, "dan" referred to dawn, and "xiu" meant divorce papers, which are similar to today's divorce complaint. "Sheep and Rat meeting once will end" refers to the marital compatibility left by ancient people; those who have the attributes of sheep and rat will have difficulties in their marriage.
