What did Brother Xueba do wrong?

I am particularly rebellious because of my mother's preference.

Xueba's brother was hugged by the whole family, and his brother couldn't bear it, exposing his scandal on the spot. My younger brother is also full of resentment against his mother, who wants to mediate the relationship, so she goes to the program to mediate the problem.

When he grew up, his younger brother was excellent and beat his mother crazily. Mother regrets everything, too. So for mothers, treat their children equally. There can be no preference.
