Why did Wang Guowei say that he despised Confucianism and Taoism in Yuan Dynasty?

Because Yuanqu was the product of the Yuan Dynasty, the status of Han and Confucianism was low at that time, so-called eight prostitutes and nine beggars.

Originally, Confucianism aimed at governing the country as an official. In the Yuan Dynasty, even prostitutes were inferior, let alone the idea of governing the country. Therefore, most of the contents of Yuan Qu reflect the passive seclusion, cynicism or debauchery of Confucianism. It does not conform to Confucianism, and it is also different from the poetic style since the Tang and Song Dynasties. So later Confucianism did a lot.
