When it comes to bullying the ice in the corner at the peak, we have to start from the previous episodes of Dear Mom and Dad. That day, Jiang Lin was standing at school and suddenly ran past two classmates. After seeing Jiang Lin, he asked Jiang Lin to keep a secret for them. Later, when the teacher walked over, Jiang Lin realized that the peak had broken the school street lamp. Jiang Lin didn't give the principal offender to the teacher. The teacher was very angry and asked Jiang Lin to call his parents, otherwise he would be expelled from school. In desperation, Jiang Lin had to call Liu Biyun to school. After Liu Biyun arrived at the school, he explained to the school. The school said that if the two principals do not admit it, Jiang Lin will still be punished. Liu Biyun persuaded Jiang Lin, but Jiang Lin refused to tell the school for a little loyalty. When Bing knew about it, it was intended to reduce the trouble for his mother Liu Biyun, so he told Liu Biyun. Later, the school gave the two principals greater punishment, and Jiang Lin was a lighter punishment.

When Jiang Lin saw that things were settled, he asked Liu Biyun. Liu Biyun told him that Jiang Lin's unreasonable tolerance was wrong and that someone was braver than him. After learning that it was ice that tipped off the school, the peak of heavy punishment blocked the ice in the corner and beat it up. After the family saw the scar of ice, they asked nothing. But when Jiang Lin saw it, he knew that these two men had done it. The next day, Gao Feng and his wife tried to commit violence against Li Bing, and Jiang Mei arrived in time to stop the violence. After Jiang Lin knew it, he also said that he would send ice home with his classmates in the future to ensure the safety of the ice.

In Dear Mom and Dad, Li Bing and Jiang Lin are obviously different roles in personality characteristics, so their ways of dealing with things are different because of different family environments. But both of them are good children, insisting on their own inner choices, so they have become good brothers, accompanying each other and helping each other.
