In discussing the case of Wang Yue and a later incident in China , in which CCTV footage from a Shanghai subway showed passengers fleeing from a foreigner who fainted , UCLA anthropologist Yunxiang Yan asserted that the reactions can be explained by deeply seated historical cultural differences in Chinese agrarian society , in which there was a stark contrast between how individuals associated with ingroup and outgroup members , saying , " How to treat strangers nicely is one of the biggest challenges in contemporary Chinese society ... The prevailing ethical system in traditional China is based on close-knit community ties , kinship ties . " He continued , " A person might treat other people in the person 's social group very , very nicely ... But turn around , when facing to a stranger , and ( a person might ) tend to be very suspicious . And whenever possible , might take advantage of that stranger . " . To amend what happened in this situation for the future , discussions were started by many government departments and officials about punishing bystanders who refuse to help people that clearly need help . On August 1 , 2013 , the " Good Samaritan " Law was put into effect where people would be penalized for refusing to help in similar situations
