As in all of China, be careful. You can be robbed, especially in less populated areas. Prostitution is widespread in Dongguan, and many men from Guangzhou, Shenzhen and especially Hong Kong flock here on the weekends. Lastly, a lot of the police force is corrupted, but since the government is still watching over them, they are discreet. So if a policeman tries to get money from you, calmly reply to him to see a superior.
