I think the article is correct as it is written. You take a school in an impoverished neighborhood mix in language difficulties and it becomes much easier for these things to occur. Add in the fact that chinese television doesn't display black people in a positive light. All it takes is one word to set thing off.<p>I know this because through the early to mid 90s there was a huge wave of haitian and cuban immigrants to my school. Because of language barriers and cultural differences there was constant fighting. Then they formed gangs and what started as 1on1 or 2on1 escalated to 30-50 people. The main difference was the school was good with enforcement so the fights always occurred offcampus.<p>Eventually, the haitian immigrants learned english and everything calmed down after that. But this school should definitely be doing more.
