Whenever there is a fight between anyone we should stop them to fight and here we also do that .

Some students are having a fight in school playground then we should stop them from fighting and if they do not then we should inform this to any teacher.

I can persuade them by telling that they could also talk to anyone says any elder to solve their problem except fight. 
By telling them that anger is the greatest enemy of
 ourselves so we should avoid this.
