Sun Hongwei exercises on a treadmill at the gym in Jinjiang District, Chengdu City, southwest China's Sichuan Province, June 11, 2019. Sun Hongwei, the son of 59-year-old Guan Yongkang, was born with cerebral palsy in 1995 and suffered from amyotrophy. Sun ever received professional rehabilitation training in training courses organized by Chengdu Qingyang Federation of Disabled Persons in 2004. Later he stopped the course because of overage. In 2015, his father Guan decided to take him to practice in the gym. After a period of searching, a gym accepted this special fitness. Moved by the strong father and son, the head of the gym also saved their venue fees. Over the past four years, Guan has become his son's private trainer. He says he will stick to it, which is his responsibility as a father. (Xinhua/Xue Yubin)
