The first comprehensive survey of 7,025 Chinese primary schoolchildren found that 24% of respondents reported that they had sometimes physically bullied another child. When children observed school bullying, 56% said they immediately reported it to their teachers. Another 20% tried to stop the bullying by approaching the bullies. The study also identified factors associated with bullying.

On the basis of the research findings, potential methods of bullying intervention are discussed. (author's abstract). Restorative practices are discussed among the interventions.
