First of all, do you know if your brother is a person who loves to learn? What's your brother's temper? Who does he listen to most, or what does he fear most? My friend's mother, her son is addicted to the internet every day, and the college entrance examination is coming soon. His mother smashed the computer on the spot in a rage, the night before the college entrance examination. Come back after talking enough, and you really did, but I didn't expect him to go back after playing for a certain time, and he was admitted to the university, so you can prescribe medicine according to your brother's personality.
