Paris, France, 04 september 2016. Thousands of chinese demonstrated after one of them, Zhang Chaolin, had been murdered in Aubervilliers, in a neighbourhood where many arabs and blacks live as well. Chinese have been the target of thieves these last years knowing that many of them won't complain to the police and also because they think they are rich and use cash. Racist prejudices whose this community known for its quitness is fed up with and come out from their usual silence and shadow. They clamed safetyness especially for those who live in the neighbourhoods.They already organise themselves in order to selfdefense.
