Great travel gets better

Yunnan province continues to upgrade its tourism options with apps, 'smart toilets' and improved farmhouse visits. Xu Lin and Li Yingqing report.

Visitors to Yunnan can not only use a phone app to locate restrooms but also to know the stall and urinal availability, air quality and temperature of the province's "smart toilets".

The app Youyunnan, which literally means "traveling in Yunnan", is part of the province's push to advance smart tourism to upgrade the sector in ways that contribute to ecological-civilization construction and rural revitalization.
