Star tour guide's dedication: 16 years in tourism, not a single complaint

In 16 years working as a tour guide in Yunnan province, Zhang Yu has never received a complaint. That's quite a feat for someone who has welcomed over 40,000 tourists and works in an industry where dealing with dissatisfaction is part of the job. As a result, he's the first tour guide from Yunnan to win a National May Day Labor Medal.

At the Yunnan Lijiang White Deer Travel Agency, Zhang is known by his colleagues as the "fire extinguisher"－for whenever there is a problem, he's always the one to solve it.

"We often encounter picky tourists, but as a tour guide, our job is to smile and listen patiently to their complaints," Zhang said.
