Campus policeman with heart of gold

Business cards carrying Xia Qingliang's name and contact number are almost ubiquitous on the campus of the South-Central University for Nationalities in Wuhan, Hubei province.

As the only police officer covering a college with 26,000 students, 60 percent of whom are from ethnic minority groups, Xia makes sure he has a strong presence and that people know how to get in touch with him.

Teachers say the 58-year-old is seen as a father figure among students because of his diligence and kindness.
