Shanghai's graffiti artists are given new legal canvasses as municipal tourism authorities list spray-painted walls among the city's official travel attractions. Wu Ni reports in Shanghai.

Shanghai's graffiti artists are being encouraged to spray what they want to say on several university walls the Shanghai Tourism Administration recently listed as tourist attractions.

The walls of many universities, such as Shanghai Jiaotong University, Tongji University, Fudan University and the University of Shanghai for Science and Technology (USST), have long been covered with their creations.

The schools even whiten the walls once or twice a year to create new canvasses.

USST's graffiti wall is divided into several sections, totaling about 500 meters. The student dormitory building is also festooned with spray-painted imagery.

Residents and tourists flocks to the increasingly acclaimed wall to snap photos, graduate Yang Yun says.
