It's already this kind of film, so if you have trouble, just say it directly, okay? Could it really be a bug?
Even at the end of the film, it was not clear why the army chief had to carry the two mothers and daughters out alone. But the explanation I decided from the beginning was that it must have something to do with the heroine's father selling him.
The family that bought the old man should have ties to the military. They bought the old man's life, but they didn't want to spend 100,000 yuan. Just as the army needed to go out and clear civilians at random, they asked the army chief to kill the old man's family as well. So, the old man felt that he could help his family by sacrificing himself, but he almost killed them.
By extension, the rules made by the upper class, the lower class can't benefit from it no matter what, except to resist, there is no way.
