Let's compare Lu Xun's works with his own. Sister-in-law Shansi in Tomorrow and Sister-in-law Xianglin in Blessing are both mothers devastated by feudal ethics. They were extremely obedient under the constraints of feudal theocracy and feudal ethics, born in pain and died in pain. Even to death, they don't understand the source of their tragic fate. Lu Xun endowed Ai Gu in Divorce and Zi Jun in Mourning for the Past with democratic and progressive ideas, and they made much progress than San Gu Liu Po and Xianglinsao. They know how to fight, but they still unconsciously obey the feudal ideas in their hearts, which is also the root of their tragic fate. I hope it helps you.
