1. Strictly stop: violence or attack is unacceptable for whatever reason. If a sister hits her younger brother, she must stop it immediately and let her know the seriousness of this behavior.
2. Communication education: Have an in-depth conversation with my sister to find out why she hit her younger brother, explain the harm this behavior does to her, and help her understand how to solve the problem in a better way.
3. Guide reflection: let my sister reflect on her behavior and help her analyze the influence of this behavior on her brother and others. Let her know that beating her brother will hurt her self-esteem and trust.
4. Establish a reward and punishment mechanism: Establish some reward and punishment mechanisms to help my sister control her emotions and behaviors. For example, if an elder sister can control her emotions and avoid hitting her younger brother, she can give some rewards. If she can't, she must bear the corresponding punishment.
5. Provide support: If your brother is injured, you must provide necessary support and care, including medical and psychological support. At the same time, help and support should be provided to my sister to help her better handle her emotions and behaviors.
In short, it is a bad behavior for an elder sister to beat her younger brother, which must be stopped and corrected in time. Through in-depth communication, guiding reflection, establishing reward and punishment mechanism, and providing support and care, it can help my sister to better handle her emotions and behaviors and avoid this kind of behavior from happening again.
