Hol Xil's wildlife protection patrol team was established in 1991. The team's efforts have seen the animal population record a significant growth over the years. But it has also brought hardships for the protectors. /Chinanews Photo

Besides the harsh weather and tough living conditions, members of the patrol team routinely face life-threatening attacks from armed poachers and even from pack of wolves at times. /Chinanews Photo

Hol Xil has an average elevation of 4,600 meters, making it an ideal habitat for about 230 wildlife species, including Tibetan gazelle and wild yak. Last month, Hoh Xil has been on the list of UNESCO's World Natural Heritage sites. /Chinanews Photo
