In order to criticize "The Life of Wu Xun", Jiang Qing and her followers went to Shandong to do research. They found another historical figure, Song Jingshi, a peasant uprising leader of the "Black Flag Army". They thus erected Song and Black Flag Army as revolutionary examples to further denounce Wu Xun. However, a dilemma was encountered by Zheng and Sun Yu during the writing of the script. In the real history, Song Jingshi eventually surrendered to Qing Dynasty; but for political purpose, Song had to be depicted as a determined revolutionary. A compromise was finally reached with Song's surrender being shown as a mere tactical move in the film.
