Mount Qomolangma, known in the West as Everest, is the highest mountain on earth, and people dream of standing on top of it. However, tragedy easily can happen -people die due to extreme cold and oxygen deficiency. And, there is a group of brave souls stationed at Mount Qomolangma most of the year. Their main task: Rescue challengers who get stuck with one foot in the grave.

Meet Qin Ziwei, born in 1999, a Chinese immigration police cadet at the Qomolangma border police station. He joined the station three years ago. For him, a dream came true.

QIN ZIWEI, CADET QOMOLANGMA BORDER POLICE STATION "I learned that Qomolangma is in Tibet and was attracted to it. So I decided to come to Tibet. I never imagined I could be so lucky as to be stationed here - looking up to Qomolangma every day."

For Qin, he is still in his honeymoon stage with the world's highest mountain. Sitting next to Qin is the station chief who learned the danger hidden behind the astonishing view of the mountain the hard way.

HE GUOWEI, CHIEF QOMOLANGMA BORDER POLICE STATION "When we are out rescuing, it is possible for us to visit places 6-to-7 thousand meters above sea level."

High altitude is not the only enemy.

HE GUOWEI, CHIEF QOMOLANGMA BORDER POLICE STATION "Sometimes, we also enter glaciers to rescue. It is extremely dangerous. We can hear ice cracking and falling."

He said his team goes out ten times or so each year to rescue eager challengers who can't follow the rules and try to conquer Qomolangma without authorization. And there was one time He himself had a close brush with death.

HE GUOWEI, CHIEF QOMOLANGMA BORDER POLICE STATION "Around October in 2016, the first alarm I received after getting stationed here was two tourists broke our perimeter and trespassed into Qomolangma's Rongbuk Glacier."

They spent over twelve hours maneuvering the glacier without food when He fell.

HE GUOWEI, CHIEF QOMOLANGMA BORDER POLICE STATION "The only thought I had was that I had to get out for my families and comrade."

I spent about a half day at the Qomolangma Base Camp where the police station is. That's about 5,000 meters above sea level, and I had to stop several times to gasp for air just to finish the interview. Never mind patrolling and rescuing - I could barely walk on a small incline.

The mission that He barely survived also imprinted in 20-year-old Qin Ziwei's mind. I asked if he still wants to climb to the top of the mountain, he said no. But when asked if he wants to be stationed elsewhere, he also answered no - he even plans to stay around for about ten years and when duty calls, he said, he will do what fellow officers have done to keep the region in check and preventing blood from reddening the beauty gifted from Mother Nature.
