After Sanruan robbed the birthday card, he took his mother to Liangshan. Why didn't Li Kui take his mother after he went to Liangshan?

First of all, Li Kui knew that his mother did not want Liangshan, so he did not tell his mother where they were going. He just said they were doing fine. Li Kui could not live up to his mother. In a few days, she will know what Li Kui is doing. If Li Kui's mother knew that her son had become a bandit, Li Kui's mother, who had been sick, would be furious if she went to Liangshan.

Secondly, it is said that Li Kui’s mother is a kind old lady. Such people should not go to Liangshan. Shi Naian wrote that Mrs. Lin was dead and she was not allowed to wait until the day Lin Chong came to pick her up. She didn't want Li Kui's mother to get a bad name. Being eaten by a tiger is the best ending.

Li Kui’s mother is blind. Who will take care of her when she goes to Liangshan? Li Kui will always serve his mother. Of course, Li Kui will be distracted and will not actively participate in many things. Song Jiang and Wu Yong need him, and Liang Shang needs him. Li Kui and his mother have been together for a long time. His mother's heart will warm him. Li Kui's character will change. He wouldn't kill so many people. Li Kui does not need to exist, nor does he have any part.

Actually, it is to show her filial piety. This kind of filial piety is very selfish and self-centered. I am old and blind. My brother takes care of her at home. At this time, she was asked to go to Liangshan. Even if she is not eaten by a tiger, she cannot live in Liangshan. In a word, the reason why Li Kui's mother did not go to Liangshan to enjoy happiness is that Shi Naian believed that a good woman like Li Kui's mother was someone like Mrs. Lin, and it was unreasonable for such a person to go to Liangshan. The reason has nothing to do with Li Kui.
