Confucius said, "Shun has five (capable) ministers, so the world is (well) governed. Zhou Wuwang said:' I have ten advisers and generals who (with one heart and one mind) created the Zhou Wang rebellion (I'm not worried that I can't defeat Zhou Wang and unify the whole country). "Confucius then commented:" (The ancients said) talents are rare, aren't they? Only after Yao and Shun arrived in Zhou Wuwang can they be called talented people. (However, among the ten people mentioned by Zhou Wuwang), there is a woman (white note: Wu Wang's wife is in charge of internal affairs), but there are actually only nine people. "
