What does Xunzi mean by "dual-use in Wang Ba"?

Interpretation: Use both etiquette and law to govern the country in an all-round way.

"Wang" refers to the Confucian theory of serving people with virtue and advocating the rule of benevolence and righteousness. "Ba" refers to legalists' persuasion by force, advocating utility and violence. Xunzi's "Wang Ba can be used at the same time" refers to the combination of etiquette and law to comprehensively govern the country.

Xunzi (about 365438 BC+03 BC-238 BC), Ming Qing, was born in Huaxia (Han nationality) and Zhao at the end of the Warring States Period. A famous thinker, writer and politician, he is called "Xun Qing".

Xunzi developed Confucianism. On the issue of human nature, he advocated the theory of evil nature, advocated that human nature was evil, denied the innate moral concept, and emphasized the influence of acquired environment and education on people. His theory is often compared with Mencius' theory of good nature by later generations, and Xunzi has also made considerable contributions to sorting out Confucian classics.
