Originally, Lu Chuan designed a rape scene for Gao Yuanyuan as Jiang, but Gao Yuanyuan collapsed during the filming. She shouted at Lu Chuan. How could she shoot like this? Finally, Lu Chuan failed to convince Gao Yuanyuan. Except for three Japanese actors who came to China for the first time, most of them were Japanese students studying in China. Hideo Nakaizumi was chosen by Lu Chuan after watching more than 200 Japanese actors in turn. The drums for shooting Japanese sacrifices are fake drums made in Henan, and hundreds of thousands are made in Japan. When shooting this paragraph, the original two Japanese drummers began to feel that the drum head was too soft and the sound was not correct. Finally, the problem was solved by lighting the drum surface for 2 hours to make it nervous. When filming the scene of the priest, the Japanese drummer was dissatisfied with a China extras joking when filming such a serious scene, so he waved and punched. China's extras are all from the martial arts school and immediately surrounded them. Fortunately, the staff dissuaded them in time, otherwise it almost turned into a group fight. There is a scene where one day after killing Tang Xiaomei, she walks into the street. Suddenly, a man shouted that he was going back to Japan.
