Everest Exped on Instagram: "A cancer survivor. A double amputee. Four failed attempts on Everest. And yet, at 69 years old, on his fifth attempt, Xia Boyu finally stood on the roof of the world, summiting Mount Everest (8,848.86 m) on 14 May 2018. This video shows him crossing a ladder in the deadly Khumbu Icefall, one of the most dangerous sections on the mountain. No excuses. No limits. Whatever your passion is, never give up. 🙏🏼 Video ©: Xia Boyu Archives. #everestexped #everest #mountever
