Zi Gong, a Confucius student who said Miscellanies of the Book of Rites, went to see the sacrificial ceremony with Confucius. Did Confucius ask Zi Gong to give (Zi Gong's name) pleasure? "Zi Gong replied that if people in a country are crazy, they will get unknown pleasure." Confucius said that Zhang and not Chi, civil and military can not also; Easy and not open, both civil and military; Once relaxed, the way of civil and military affairs is also. "Wu Wen refers to Zhou Wenwang and Zhou Wuwang who are good at governing the country. The meaning of this passage is that the bowstring has been pulled tightly without relaxation, which Zhou Wenwang and Zhou Wuwang can't do; On the contrary, it has been relaxed and not nervous, which Zhou Wenwang and Zhou Wuwang are unwilling to do; Only by being nervous and relaxed, combining work and rest, combining leniency with severity, is Zhou Wenwang and Zhou Wuwang's way of governing the country. The way of civil and military affairs is to govern the country well, that is, to let the people combine work and rest, to combine work and rest, and to let work and life proceed rhythmically.
