Mountain patrolmen keep record from a distance

Trekking 30 kilometers in the Ailao Mountains of Xinping county, Yunnan province, over four days recently proved to be quite a challenge for many of the 30 participants who were new to the area.

But to the oldest patrolman with the Ailao Mountains National Nature Reserve's Xinping Bureau, it is just a day's work.

"With a bag and a bottle of water, I can easily cover the route in a day," says 59-year-old Wang Jiahe.
