Seven-year crusade to stamp out spitting and other poor behaviour is paying dividends
Wang Tao, president of the non-profit Green Woodpecker Association, has been on a mission for the past seven years - convincing people to behave in a more civil way in public. Each week, Wang and other volunteers go out on the streets to persuade their fellow Beijingers against such antisocial behaviour as spitting, ignoring red lights or even walking around shirtless. Years of experience have convinced Wang that people can modify their behaviour in public.
