Zhang Hong ascended to the peak of Mt Everest in total darkness.
The Chinese mountaineer is now the first blind person in Asia and only the third in the world to do so.
But even when he made it to the top of the tallest peak in the world, he says his lack of sight kept him from celebrating too much.
"When I got to the top, the sound of the wind was extremely scary. It was like a howl, so I was very scared. After reaching the peak, I didn't feel exhilarated or emotional like other climbers. I did not think too much, as I thought that the environment around me was quite risky so I told my guide that I wanted to get down quickly. Because I knew getting to the top was only half the climb."
The 46-year-old scaled the mountain from the Nepal side.
He completed the almost 9,000 meter-high Himalayan feat on May 24th, along with three high altitude guides and returned to base camp just three days later.
"No matter if you're disabled or normal, whether you have lost your eyesight or you have no legs or hands, it doesn't matter as long as you have a strong mind, you can always complete a thing that other people can't."
Zhang lost his sight at the age of 21 due to glaucoma.
But he says he was inspired by Erik Weihenmayer, a blind American mountaineer who scaled Everest in 2001.
Nepal reopened Mount Everest in April for foreigners after it was closed last year due to the global health crisis.
