In 2017, Sun received several awards, including the Laureus Chinese Sportsman of the Year Award and Most Popular Male Athlete Award. The International Swimming Federation (FINA) also honoured him for his contribution to swimming popularity in China.
Sun Yang's career has not been without its difficulties. He faced a recurring back injury in 2018 and a high fever during the 1500m heats at the 2016 Rio Olympics, which affected his performance. In January 2016, he broke a bone in his right foot but returned to training by March.
In 2015, he withdrew from the 1500m freestyle final at the World Championships due to heart problems. Earlier, in February 2014, he underwent foot surgery for a toenail infection.
Sun Yang's career has also been marred by controversies. In June 2021, he was suspended for four years and three months by the Court of Arbitration for Sport (CAS) due to a confrontation with anti-doping officials in September 2018. This suspension followed an annulled eight-year suspension imposed earlier.
In 2014, Sun was suspended for three months after testing positive for trimetazidine, a banned substance. He claimed it was part of medication for a heart condition and was unaware it had been added to the banned list that year.
Sun Yang resides in Hangzhou, China, and speaks Mandarin. He pursued higher education in Sport Studies at Zhejiang University. Additionally, he has studied for a master's degree in physical education at Soochow University and began his PhD in human kinesiology at Shanghai University of Sport in 2018.
Sun Yang looks up to Chinese swimmer Zhang Lin as his idol. Outside of swimming, he enjoys music as a hobby. His sporting philosophy is encapsulated in his motto: "You succeed when you believe that you can succeed."
Sun comes from an athletic family. His father played basketball for Anhui Tigong, while his mother competed in volleyball for Zhejiang Province.
Despite facing numerous challenges throughout his career, Sun Yang remains a significant figure in swimming. His achievements have left an indelible mark on the sport in China.
