The ancients often said that”the birds are exhausted, the good bow is hidden, the cunning rabbit is dead, and the running dog is cooked”. In many cases, once they have no value for existence, maybe life will end here. Some people like to pursue fame, some people like to pursue wealth, some people like to pursue rivers, mountains and beauties, and everyone may be a”snob”. On the way of pursuing these, if they don’t know the evidence of advance and retreat, they will bring about the consequences of family defeat and death, The ancients said,”there are three endless people, and when they do, they will fall”. Do you know why?
