62-year-old Zhang Jianxing has been searching the ancient forests of the Shennongjia National Nature Reserve for over two decades.

Jianxing began living in the 3,200-square-kilometer mountain range in 1994, after becoming fascinated with the Yeren(also Chinese Wild Man), a 6-foot-tall humanoid creature covered in thick red-brown fur. References of the so-called Chinese Wild Man date back to the Zhou Dynasty in the works of classical Qu Yuan.

For 10 months out of every year, for the last 22 years, Jianxing has been living deep in the Shennongjia National Nature Reserve, hoping to meet the Yeren. Dressed in military gear and armed with a camera, he constantly looks for clues of the creature, living off the land and sleeping in abandoned homes and empty caves. To him, the Yeren is more than just an old myth, it’s a branch of scince, one that he has been studying for a very long time.

Jianxing claims he has collected enough evidence of the Wild Man’s existence---over 100 hair samples and 3,000 photos of large footprints---adding that he even came close to seeing it for himself no less than 19 times. And he is not alone in his beliefs. The Wild Man Research Association----yes, there is such a thing---records show reports of Yeren encounters from over 400 locals.

But with no concrete evidence to prove the existence of the Wild Man, most scientists regard it as nothing more than a legend.

Jianxing also added that the local government in Hubei is relying on the Yeren to boost its tourism revenues. In 2012, the Shennongjia Nature Reserve signed an agreement with Beijing to promote holidays for Yeren hunters.
