Advanced technologi­es revitalize old town of Yunnan

- (Xinhua)

In a matter of seconds, Qian Yafen can easily locate the nearest vacant toilet on her cell phone.

“I downloaded an app, clicked ‘find a restroom’ and then they just came up, with pictures of nearby public restrooms, numbers of available toilets as well as maps showing how I could get there,” Qian said.

She picked the nearest one and scanned a QR code on a tissue box after entering the restroom, which distribute­d free toilet paper.

“It’s brilliant! It helps avoid waste and solves my problem so quickly in a way that I’d never thought of,” she said.

Qian is visiting the Old Town, a famous UNESCO World Heritage Site with an 800-year history in the city of Lijiang, Yunnan province, which attracted more than 14 million tourists last year.

All 30 public restrooms in the Old Town are two-story buildings with traditiona­l characteri­stics of Naxi, the native ethnic group. Two LED screens hanging at the entrance of each restroom designate both the men’s and women’s room as well as a unisex room. The screens also display the real-time temperatur­e, humidity, and the concentrat­ion of hydrogen sulfide and ammonia gas.
