 In order to avoid the censorship of the film by the two government censorship agencies in Nanjing and Shanghai.The script of "The Big Road" tried to avoid the prohibited words, and writes "Japanese imperialism" as "enemy country", "Japanese aggression invades China" as "advancing artillery fire", and changes "Chinese land" to "the land of weak nations" ", writing "resistance against Japan and salvation" as "resistance for self-rescue", "war for survival of the nation", prompting "a large area of land" to the occupied Northeast China, etc.Despite this, the patriotic sentiment of the film is also very incisive, the message remain clear, and the national song composer Nie Er made several songs for the film.
