What is Beijing Shunyi, renhe town and henan village? If you do something serious, will you be cheated or in danger?

There is a famous "three no matter" area, which is the settlement of Henan people. The black forces are very strong. Usually the police don't come forward to fight. It is the black forces of local bars and KTV who are managing and mediating. Because you generally don't have "certain strength", you absolutely dare not make trouble, so I advise you not to go. Nicknames are important unless you know their "anti-hegemony", of course, that is another matter.
