Trash-talking millionaire cleans up the streets

Zhong Congrong is on a mission to stop littering and doesn't mind getting his own hands dirty

Zhong Congrong is so passionate about cleaning up rubbish his wife sometimes worries about his personal safety.

Around Chongqing, he harangues people who litter and chases them through the streets if they don't pick up after themselves. At night, he goes to restaurants and exhorts diners through a mini microphone not to leave a mess.
