Was there a campaign against pornography and illegal publications in ancient times?

In the history of China, there were official prostitutes in the Guanzi period in the Spring and Autumn Period, which lasted until the middle of the Ming Dynasty. The earliest official brothel in China was opened by Guan Zhong, the prime minister of Qi in the Spring and Autumn Period, in the middle of the 7th century BC. Warring States policy? "There are 700 women in the Seven Cities Palace in Qi Huangong" was the policy of the Eastern Zhou Dynasty. In the Qing Dynasty, Yong Zhengdi ordered the whole country to abolish the music system, and the state no longer officially supported prostitutes. So there is no history of cracking down on prostitutes.

Historically, it was mainly in the form of literary inquisition, but it mainly served the politics at that time.

Therefore, it can be confirmed that in ancient China, there was no "yellow fight" in the current definition, but there were steps to unify thoughts and strengthen rule.
