Anger is usually a response to danger. It is also a form of self-expression, and sometimes, a way for children to show their independence. For little children, it is also a cry for help. During the lockdown, schools are closed and children are at home. They are not able to go out and play or interact with their friends. This causes frustration in children, resulting in aggressive behavior. There are plenty of other reasons for young children to be angry about it.
