The song is called "The Japs Enter the Village". "Japanese Entering the Village" is a purely musical song that first appeared in "Plain Guerrilla" filmed in 1955. Later, this song "The Song of the Japanese Entering the Village" was quoted in many domestic anti-war movies. I have been listening to the very classic "Japanese Enter the Village" accompaniment from the anti-Japanese movie "Plain Guerrillas" for so long. The tune is a musical excerpt from Shostakovich's Seventh Symphony "Leningrad". ?

When it comes to the Seventh Symphony "Leningrad", no one has heard of it, but when it comes to "The Devil Enters the Village", most people are very familiar with it and can even hum it. The atmosphere of this piece is eerie, tense and comical. Originally the composer described the German fascist invasion of the Soviet Union, but it was later borrowed by domestic anti-Japanese films to describe the tense atmosphere when the Japanese invaded.
