How can families handle the problem of their child being bullied through social media?

I have thought that if my children were bullied at school, what could I do. I can\'t find any positive solution about it. Because it is their problem. I don\'t think it is good idea to intervene their problem. If parents try to solve the problem by intervening children\'s relationship, the problem will be more serious. Bullying has been a serious problem in nationwide already. Although our government tried to find the solution, there are still a school bullying,a school violence and sexual harassment. As a parents, the best way to protect their children from the school violence is training them physically and mentally with proper ways. I think that a strict upbringing is the most important factor to save their children from a various threaten. However, if children have been suffering from the school bullying, to contact the professionals or polices and get advice are the choices that parents do.
