Summer is ending, and school bells are about to ring once more. It's time for many to get serious about college life.

For some students this will be their first time away from home, the first occasion perhaps that they have had to take responsibility for themselves.

Usually it's an adventure, but some realities of campus life may come as a shock - threats to physical safety being one of them.

Kang Chenwei, a junior student at Beijing Normal University, has drawn a map by hand and posted it on his WeChat account.

It's not to show the location of the library, or canteen.

This map outlines the places where female students should look out for potential attackers.

This map, in the form of a scatter diagram, was created as part of his research paper on campus sexual harassment in China today, and is based on 60 recent cases.

According to statistics collated from Beijing Normal University's billboard system, five cases concerning sexual harassment have been reported in just one week - from August 18 to 25.

But most universities usually fail to tackle sexual harassment, and seldom inform students about the best ways to protect themselves from potential attacks.

Kang Chenwei told the Beijing News that he hopes his map will raise people's awareness of the issue, and there will be greater pressure from the public to take more vigorous action against it.

The map is also proving a useful tool for the regular security job on campus, as it points out some blind spots in its coverage.

One female student at the university welcomed the map, praising it for the way it shows data based on geographical location.

She further pointed out that Kang's report could be made even more comprehensive if it were to include interviews with victims, rather than simply providing an analysis of perpetrators' activities.
