The May 4th New Culture Movement and other new cultural camps and the left-wing literary and art federation under the leadership of Mr. Lu Xun, "The new literary camp is constantly fighting against the Mandarin Duck and Butterfly School while criticizing the retro argument". They believe that the "literature" of Yuanyang Butterfly School was born in the semi-colonial "Shili Yangchang" and was popular in the years after the failure of the Revolution of 1911. When people start to wake up, it is the anesthetic and confused soup on the road. Although a few works have exposed social darkness, family despotism and warlord cruelty to a certain extent, their general tendency is nothing more than "thirty-six strategies are the best, and a pair of butterflies are the followers", as Lu Xun said, "a new talent+a beauty" and "love is inseparable, and Liu Yin flowers are like a pair of butterflies and a pair of mandarin ducks". Advertising interest doctrine, mostly vulgar in content and empty in thought. "Talking about love can't get out of the stereotype of talented people and beautiful women stealing flowers and jade. Talking about politics and talking about society is nothing more than lamenting that people's hearts are changing."
