A car attack that killed 35 people in China has sparked questions about a recent spate of public violence, as officials continue to censor discussion on the incident. On social media, many are discussing the social phenomenon of "taking revenge on society",

Chinese authorities took almost 24 hours to officially disclose that a driver on Monday evening rammed his car into a crowd at a sports centre in Zhuhai, killing 35 people and severely injuring 43 others.
