Chen Yue, an office worker in Xi'an, is plagued by poor health when he happens to set out on a hike in the Qinling Mountains. Starting from Guifeng Mountain, he checks off a hundred peaks across the Qinling range, figures out his gear budget, masters wilderness skills, explores mountain legends and temples, and samples the local specialties at the trailheads. From an office worker with little stamina to an accomplished hiker who conquers deep valleys and high altitudes, climbing transforms him from the inside out and teaches him that life is like a mountain climb: keep putting one foot in front of the other, and eventually you will reach the summit.
