Sui/Han teamed up in 2007 without having previous pair skating experience. They both are inspired by 2010 Olympic Champions Xue Shen/Hongbo Zhao and started skating after watching them competing at the 2002 Olympic Winter Games. Zhao is now their coach. Sui/Han have landed throw quadruple Salchows and quadruple twists in competition. The couple missed most of the 2012/13 season as Sui was recovering from epiphysitis. They also missed the first half of the 2016/17 season as she underwent surgery on both feet in spring 2016. They sat out the 2018 Grand Prix as she recovered from a stress fracture in her foot.
