We make direct contact with sex workers at their workplaces -- the streets, one-sex worker apartments, foot spas, massage parlours, saunas, karaokes, nightclubs and bars etc. in various districts of Hong Kong for health education and human rights promotion. We also pay close attention to and use online social platforms and mobile apps to contact sex workers who are active on the Internet, in order to promote AFRO's services, and deliver messages on health and rights promotion.
