The Chinese City Management Administration and Implementation of Law , also known as Chengguan , is a government agency that has been established in every city in the People's Republic of China, whose officials are responsible for cracking down on unlicensed migrant workers. According to the BBC, "Ever since the agency came into existence 10 years ago, there have been repeated criticism of them using excessive force. This para-police force, equipped with steel helmets and stab-proof vests, is often used by local officials as trouble-shooters".
In general the Chengguan serve as an official agency employed by cities across China "to tackle low-level crime." However, the agency is widely disliked by the Chinese due to their alleged abuses of power.
