1. Observe the child's behavior and find out the reason why she hit and pushed. Maybe it's because she feels angry, dissatisfied, or wants to attract attention. Knowing the reason, you can better help her solve the problem.

2. Give children a clear code of conduct. Tell her that hitting and pushing people is a bad behavior, which will hurt others' feelings and bodies. Let her know what the right behavior is.

3. Provide appropriate punishment for children. When she hits or pushes people, you can take appropriate punishment measures, such as asking her to apologize or temporarily prohibiting her from participating in certain activities. This will let her know that her behavior is not allowed.

4. Encourage children to express their feelings. Sometimes children will hit people and push people because they can't express their feelings correctly. You can help them learn to express their feelings in words, not through violence.

5. Set an example for children. As a parent, you need to be a role model for your children and show them how polite and respectful you are. This can help children learn correct behavior.
