"To find a Wildman, you have to become a Wildman first. Like wild animals, the Wildman's senses are more acute than human beings and they can easily detect an approaching person."

Li pours scorn on the large-scale science exploration teams that are occasionally organized to search for the creature.

"These guys will never find anything new like a Wildman as they make too much noise, even if they are well equipped. To find a Wildman, you have to live in the mountains and merge with nature."

Spending time alone in harsh conditions comes easy to Li, who says he has been a loner since he was a child.

Speaking of being alone in the mountains, he says: "The solitude was so strong sometimes I became numb to the outside world. In addition, there was physical weakness caused by cold and fatigue. Sometimes, I was gripped by illusions and felt I could almost see Death."

Years of unrelenting effort, however, did bring some reward as Li saw the Wildman and its footprints on several occasions.

"It was the moment that I can never forget," he says of his first encounter with the beast, on Feb 28, 1980.

The Wildman appeared to be chasing him, Li says, possibly because it thought he was prey.

"I hid behind some trees and tried hard to contain my violently beating heart, closing my eyes for a while hoping I could see it more clearly later," he says.

As the creature came nearer, he could see clearly it resembled both a man and an ape. It was about 2.6 meters tall, with red hair all over its body, no tail, two arms waving as it walked like a man.

He was horrified but even so aimed his gun and pulled the trigger. But it failed to fire, as the charge was damp. He did not have a camera.

The creature turned around and ran swiftly toward a bamboo forest.

"Seeing the creature disappear, I collapsed on the snowy ground."

"When I returned haggard to the art troupe and saw my colleagues, I tried to say hello but could not remember their names, as I had been cut off from society for too long."

Since retiring a few years ago, Li's family of three has been relying on his monthly pension of about 2,000 yuan ($313). However, Li still continues the search.

"Once I receive a witness report from the villagers, I immediately go to the scene with them to check it out."

He blames lack of equipment and manpower on his inability to provide evidence of the creature's existence.

"Although I have seen the Wildman several times, I couldn't record it because it escaped too fast, and I didn't have a good camera to record faraway objects. Besides, it is too exhausting for a single man to search in such a large area."

He has published a book about his travails, with the help of Beijing Book House Technology & Culture Co.

"Li is a little obstinate and not very sociable," says Wang Wei, a marketing manager of the company. "But he is very focused on his pursuit. It is not easy in modern society, when many people just follow the trends and frequently shift focus."

"I hope I can find a sponsor and some volunteers so that I can continue with the search," Li says. "I have devoted all my life to the search and I hope I can put an end to this mystery so that I can be relieved before the end of my life."
