What are the dross of the ancient prose view?

After all, Guanzi, an ancient literature in China, was a reading in feudal times. As far as ideological content is concerned, some articles, such as Wang Shouren's "Zunjingge Ji", are obviously feudal dross; As far as the overall selection of materials is concerned, philosophers are not selected in the pre-Qin language, and Han books are not selected in the Chinese language. The three years of Liao, Jin and Yuan failed to reflect the whole development history of China's prose. As far as authenticity is concerned, it is extremely inappropriate to select works written or disguised by future generations, such as Li Ling's answer to Su Wushu.
