Spaces have been marked in yellow on main roads in Xi'an, close to 50 of the city's public toilets, the Hua Shang Bao newspaper reports . Each one is designated as a "special toilet use" space and there's a 15 minute time limit for drivers who park in them, so anyone who tries to take advantage of the spots to go shopping will be fined. The city's traffic police are also asking people to report any cars that occupy the spaces long-term.
