The reason why Sun Yang missed the Olympics was because he was banned by the FINA in 2020. The cause of this incident can be traced back to 2018.
In 2018, the FINA banned Sun Yang once because he refused to undergo a sampling test. According to FINA regulations, athletes need to cooperate with sampling tests at any time to ensure the fairness of sports competitions and the innocence of athletes. However, Sun Yang refused to cooperate during this sampling test, which aroused dissatisfaction from the FINA.
After the ban period ended, Sun Yang continued to participate in various competitions, but his behavior aroused doubts from the FINA. In 2019, Sun Yang was investigated by the Industrial Development Bureau (WADA) in a competition for destroying test samples while undergoing doping testing. The Industrial Development Bureau conducted a serious investigation into this and finally decided to ban Sun Yang for life.
The lifetime ban is a severe penalty that means Sun Yang will no longer be able to participate in any FINA competitions, including the Olympics. This decision caused huge controversy in the swimming world. Some people believe this is unfair punishment for Sun Yang, while others believe it is a necessary measure to protect the fairness of sports and the rights and interests of athletes.
In any case, the news of Sun Yang's absence from the Olympics is undoubtedly a huge blow to him. As a leader of China's swimming team, he has accumulated many medals and honors, and has also cultivated many fans. However, this incident has created huge challenges for his career, and he will not be able to show his strength again in the world's highest level of competition.
For Sun Yang and the China swimming team, this incident is also a warning. It once again reminds athletes to abide by the rules and moral principles of sports and always remain sincere and respectful. Only in this way can they show their true strength on the field and gain fairness and justice.
