Chen Zhou, who has no legs, does pushups with 11-year-old Gao Zhiyu on his back at Laoshan Mountain in Qingdao, Shandong province. Gao, 11, also has no legs, the result of injuries in a car accident. Chen lost his legs when he was a child after falling from a train. The pair climbed the mountain together using only their hands. Chen is now a motivational speaker and has a happy family.
