Xunzi's so-called "queen king" is different from his so-called "former king" and Mencius' so-called "former king". Academic circles generally summarize Xunzi's historical thought as "after the king's law", which is opposite to Mencius' "before the king's law" In fact, Xunzi's attitude towards history is not only "the king after the law" but also "the king before the law". He is the king after the law and the king before the law.

The formation of the concept of "former king" is based on historical figures, which concentrates all the wisdom and talents of historical figures, not on the realistic level but on the ideal level, which is the key to understand the characteristics of Xunzi's former king.

Xunzi's so-called "queen king" is an idealized description of the ideal monarch at that time, which embodies all the requirements of the development of the new era. The "queen king" has become a symbol of etiquette, Wang Ba, justice and benefit. Like the "former king", Xunzi's "queen king" is also expressed at the ideal level rather than the realistic level.

Compared with the former king, Xunzi paid more attention to the value and significance represented by the "later king". Xunzi absorbed the reasonable elements of pre-Qin philosophers and adapted to the development of social situation, and put forward a series of propositions, such as paying equal attention to justice and benefit, combining Wang Ba with practice, and respecting etiquette and law. Compared with Confucianism, business and Korean legalists, Xunzi is more conducive to safeguarding national unity, while the "queen king" as the embodiment of ideal personality is the concept of justice and benefit.

Pay equal attention to justice and benefit, and respect history, ceremony and law.
