Sun Yang

Sun Yang (Chinese: 孙杨; Mandarin pronunciation: [swə́n.jǎŋ]; born 1 December 1991) is a Chinese Olympic and former world-record-holding competitive swimmer. In 2012, Sun became the first Chinese athlete to win an Olympic gold medal in men's swimming. Sun is the first male swimmer in history to earn Olympic and World Championship gold medals at every freestyle distance from 200 to 1500 metres. A three-time Olympic gold medalist and eleven-time world champion, he is the most decorated Chinese swimmer in history. In 2017, NBC Sports described him as "very arguably the greatest freestyle swimmer of all time".

In September 2018 Sun was involved in a controversial incident during an out-of-competition doping test at his home. The doping control assistant (DCA) lacked proper accreditation and took photos of Sun without his permission, leading him to refuse the blood sample collection. A security guard broke open the container to prevent the testers from taking the vials. The DCA later admitted to unprofessional conduct. FINA ruled that Sun did not violate anti-doping rules due to the DCA's actions. However, on 28 February 2020, the Court of Arbitration for Sport (CAS) overturned FINA's decision, banning Sun for eight years for tampering with the doping control process. Some analysts opined that the trial was marred by severe translation problems, conflict of interest, bias and an "absence of evidence" around doping activity. Despite this, CAS found no evidence of doping, so Sun retained his medals. On 22 June 2021, after a retrial, the CAS upheld the ban but reduced it to four years and three months.
