1. Treat your brother with tolerance. When children reach a certain stage, they will have rebellious psychology. If you let him go east, he will go west. At this time, try not to have conflicts with his brother. Don't come up with a scolding, but treat him with tolerance and understand why he is like this.
2. Be patient. Don't be impatient when communicating with your brother. You get impatient after a few words. You should be kind, lead by example, convince others with virtue, avoid unnecessary reprimands, and don't be cynical because of some mistakes or temporary shortcomings.
