Yang Feifei comes from the countryside in Nantong City, east China's Jiangsu Province. He was interested in machinery since childhood and became a technical worker in Foxconn Technology Group in south China's Shenzhen after graduation in 2003. Yang has put most of his time on pondering how to optimize technological process and improve product quality.
