Children's addiction to online games was a problem that needed to be taken seriously. If it was not solved, it might lead to a decline in academic performance, a weakening of social skills, and a threat to their physical and mental health. Here are some suggestions that might be useful: 1. Communicate with the child. Try to understand why children are addicted to online games, listen to their suggestions and ideas, and try to build a relationship of trust and respect with them. 2. Set family rules. Work with your child to set some rules at home, such as limiting the time your child can play games, and setting homework and tasks for your child to complete. 3. Find a hobby that suits your child. Try to help children find something they are interested in, such as sports, music, art, etc., to help them develop more interests and talents. 4. Offer positive motivation. Try to provide positive motivation for your child, such as rewarding him or her for completing homework on time, helping him or her set goals and plans, etc. 5. Seek professional help. If the above methods can't solve the problem, you can consider seeking professional help such as consulting a psychiatrist or finding a gaming addiction treatment center. Finally, it was important to be patient and persistent in communicating with the child and working hard to help the child get rid of the game addiction.
