　　Younger students experience school bullying (欺凌) more frequently than older ones, and male students are bullied more than their female peers, a survey found.

　　It also found that nearly half of the students had been intentionally hit or knocked down by classmates. About 6 percent said they are targeted by bullies on campus every day. The survey also found that students from ordinary schools experienced more bullying than peers from key institutions, and children from poor families are more likely to be bullied at school.

Being bullied can have a negative impact on a child's personal development and academic performance, according to Zhou Jinyan, a researcher who led the study at Beijing Normal University. 揅hildren being bullied will find it hard to trust others,? Zhou said. 揟hey may often feel anxiety, anger, resentment or depression. These emotions will further undermine their ability to control their own life."

　　In recent years, bullying on Chinese campuses has been frequently reported and has attracted widespread attention and concern. The most recent incident to arouse heated discussions took place in December at Beijing's Zhongguancun No.2 Primary School. A fourth-grade student was bullied and laughed at by classmates, causing him acute stress disorder.

　　The Supreme People's Procuratorate (最高人民检察院) received about 1,900 cases related to school bullying in 2016. Meanwhile, there was a notable increase in bullying reports involving middle school students from 14 to 18 years old.

Zhou came up with some ways to solve the problem, including boosting communication between teachers, parents and students and trying to establish more harmonious relationships among children. She said it was strongly suggested that parents try to be involved in their children's educational experience, as their presence and companionship have proved effective in reducing bullying and its negative effects.
