Improving parent-child relationship and family disharmony are the main causes of Internet addiction, so improving family relationship is very important for quitting Internet addiction. Parents should learn to communicate with their children, respect their reasonable demands, treat their children equally, and establish a democratic and equal relationship with their children, which is conducive to making their children have a loving and grateful attitude towards their parents. At the same time, parents should not give up their children. As long as the child has a conscience, the child will be moved by his parents' unconditional love. At the same time, the computer should be placed in the living room, not in the children's bedroom.
