Liu's first grand slam.

At this time, only Liu was left as the champion of men's singles in the World Table Tennis Championships. So in the final of men's singles in the World Table Tennis Championships of 1999, Liu Chenggong finally won the championship and became the first man's grand slam player in China.

In the 2000 Sydney Olympic Games, Liu was the absolute number one player in the China men's team, but at this time, Liu was actually at the end of his career, so he lost 3-0 to Waldner in the semi-final.

In the end, Kong defeated Waldner 3-2 in the final and won the men's singles title. Kong Huiling sprained her ankle in the second game, but she persisted in the game, leaving a picture of kissing the national flag madly after winning the championship.
