Sima has been suffering from Ankylosing spondylitis for fifteen years, however, she loves nature and climbing. A year ago, after suffering for 15 years, Sima's disease was finally diagnosed, and in the past year, he was able to continue as a professional mountaineer with medication and continuous exercise. I recorded this photo of him in Trekking K2, the hardest mountain in the world. 14 days of camping, 5,000 meters of climbing and more than 150 kilometers of travel in the heart of the karakoram mountain range.
