China is developing an online toilet map, aiming to help traveling tourists from home and abroad find the nearest toilets, the tourism authorities said.

The online toilet map was being developed by China's search engine giant Baidu at the request of China's Ministry of Culture and Tourism, said Zhang Xu, the vice minister, on Tuesday.

By the end of June, public toilets built before 2019 in tourist attractions, transport centers, restaurants, entertainment venues, leisure areas and parks can be located through Baidu map app, Zhang said.

So far, the location of around 20,000 toilets in those areas have been put into the system.

The app can also help travelers find barrier-free toilets.
