"Eight Hundred" is adapted from the true historical story of the Battle of Siku, the final decisive battle of the Sino-Japanese Battle of Songhu, and its ending is also a complete failure of the Battle of Songhu.
The reason why Eight Hundred was criticized by the military was that Eight Hundred did not film all the heroic deeds, and the captured national army vilified the image of our national army. For example, China soldiers killed Japanese soldiers to train their courage, which is totally out of line with China's practice. There are still some plots in the film that violate international law.
Colleagues also advocated extreme atrocities and fascism, which distorted the people of China and their sense of justice towards aggression, and aroused great public indignation and criticism from the people of the whole country.
