Li Tailang was very upset recently because his father Li Qi suddenly became responsible and always picked him up and dropped him off to cram school at night, which made him want to make excuses to tutor and go to Internet cafes with friends to go all the plans to fight. At first, he really thought that his father wanted his son to be successful and wanted him to work hard to get into a good university. But it seems that although his father was red every time he picked him up after school, he seemed to be getting tired. What's going on? So Li Tailang decided to follow his father and want to see what medicine he sold in the gourd.
