What table tennis rules have changed because of China?

1, the number of participants is limited: 1999, ITTF reduced the maximum number of participants in men's singles, women's singles and mixed doubles in the World Table Tennis Championships to seven (pairs), which made China people unable to enter the quarterfinals in these three events, while men's doubles and women's doubles were all three pairs, which made China unable to enter the quarterfinals and reduced the possibility of China winning medals.

At the Athens Olympic Games, the lottery system was reformed. In men's doubles and women's doubles, two pairs of players from the same team must be drawn into the same half-court, so it is impossible for China to win all the gold medals and silver medals.

6. Repeated restrictions on the number of participants: In 2008, ITTF imposed restrictions on "overseas corps", restricting athletes from obtaining international competition qualifications by changing their registered teams and nationalities, and preventing table tennis from becoming the world of China players.
