Does the questioner want to ask "Where does the regular script "How many flies hit the wall in Little World" come from? It comes from Mao Zedong's poem "Man Jiang Hong·He Comrade Guo Moruo". The regular script of "How Many Flies Hit the Wall in the Little World" comes from Mao Zedong's poem "Across the River and Comrade Guo Moruo". "Manjianghong·Comrade Guo Moruo" is a poem written by Mao Zedong in 1963. It was an inspiring anti-hegemonic poem that I was deeply moved by after reading Guang Moruo's lyrics in Guangming Daily.
