Since last year's Rio Olympic Games, the controversy about Ning Zetao has continued to this day. Prior to this, it was widely rumored that Ning Zetao left the national team. It is reported that a letter about Ning Zetao being expelled from the national team recently circulated on the Internet, saying that he was no longer a member of the national team and was transferred back to the navy. The media also learned from the swimming center that the content of this letter is true. The contents of the letter clearly listed Ning Zetao's specific statements of violating the relevant regulations of the State Sports General Administration and the Chinese Swimming Association: "unauthorized endorsement of advertisements", "disobedience to the national team's competition arrangements" and "refusal to participate in relay events". The prefix and signature are stamped with the seal of "Swimming Management Center of the State General Administration of Sport", and the signing date is 201610/0/0/0/8, that is, after the Rio Olympic Games.

Subsequently, the discussion about Ning Zetao leaving the national team was very heated. It is reported that Ning Zetao will definitely miss the Budapest Swimming World Championships in July this year, although the National Swimming Management Center has kept silent on this incident since the documentary in Ning Zetao was broadcast last year. Although some netizens pointed out that the official letter of the "red-headed document" was unprofessional, the authenticity of this official letter was also confirmed by the media from the authorities of the swimming management center.

Since the end of the Rio Olympic Games, Ning Zetao has faded out of the arena, and it is difficult to find him in various activities of the swimming team returning from the Olympic Games. Since September 9 last year, he has also missed a series of national team competitions such as the National Swimming Championships, the Short-course World Cup Series, the Asian Championships and the World Short-course Championships. Ning Zetao responded unwittingly to the fact that he was removed from the list. The dispute between Ning Zetao and China Swimming Team has lasted for half a year, and the information is not smooth. But what is certain is that Ning Zetao's departure from the national team is a lose-lose situation.
