Further on, the slogan "Down with xxx" has appeared in the New Culture Movement, which shows that the questioner is reasonable, and this slogan has existed since the late Qing Dynasty!
This radical slogan seems to come from works such as Jing Shizhong and Revolutionary Army. However, after careful reading of the two works, I can't find them. Further on, Liang Qichao's works also have this passion, but the works are too heavy to finish reading at one time.
Beyond Kangliang, will it be the legacy of the slogan of the Boxer period, or even the legacy of the Taiping Heavenly Kingdom? If we can find these two words in Ming and Qing literature, everything will come out!
