As far as the "three major competitions" of table tennis are concerned, in terms of pure competitive sports level, the world table tennis champion has the highest gold content, the Olympic champion has the strongest comprehensive strength, and the World Cup is regarded as the "most watery" world champion.

Many sports have the so-called "Grand Slam", athletics, diving, gymnastics, tennis and other sports have such a name, mainly refers to a player's career at the same time as the Olympic Games, World Championships and World Cup championships. Compared with other sports, the "Grand Slam" of table tennis seems to be more often mentioned, table tennis "Grand Slam" refers to a player who has won the World Cup, the World Table Tennis Championships and the Olympic Singles Championship in his career, so far, there are 10 "Grand Slam" players in the world table tennis world, and the national table tennis occupies nine of them, they are: male players Liu Guoliang, Kong Linghui, Zhang Jike, Ma Long, female players Deng Yaping, Wang Nan, Zhang Yining, Ding Ning and Li Xiaoxia The only non-national table tennis player is Swedish legend Waldner. "Grand Slam" should be the highest ideal of the career of table tennis players, and it is indeed very difficult for a table tennis player to win the world championship in three major competitions at the same time, this is true for foreign players, and it is also true for national table tennis players.
The Olympic Games, the World Table Tennis Championships, the World Cup and known as the table tennis project world "three major competitions", due to the different nature, the participants are also different, has been the three events which have a higher gold content, the more difficult to win the championship discussion has never stopped, from the scale of the event and the impact of the point of view, the Olympic Games are the most significant, the World Table Tennis Championship is the most difficult to win, the World Cup championship has the lowest gold content. After all, the Olympic Games is the world's largest comprehensive sports event, its influence is not the same as other competitions, because of the need to take into account the wide range of participation and the scale of participation in the Olympic Games, so each association has only two places to participate, which is undoubtedly a bad news for those countries or regions where table tennis is relatively good, and many world-class masters of national table tennis have not had the opportunity to participate in singles competitions in their careers, let alone won the Olympic singles championship. However, it is precisely because of the limited number of Olympic participation in the Olympic Games, including many famous players in the national table tennis, table tennis masters have been absent from the Olympic Games, the overall level of the Olympic Games has been affected, and the difficulty of players who have qualified for the Olympic Games to get good results has actually decreased. However, considering the particularity of the Olympic Games, the pressure on athletes is relatively large, and it is not difficult to win the final championship, after all, the Olympic champion means "fame and fortune", and the significance of winning the championship is incomparable to other competitions.
The World Table Tennis Championships is recognized as the highest level of all table tennis events, the most difficult to win the championship, due to the great relaxation of the quota of various associations to participate in the World Table Tennis Championships, the world's high-level players will rarely miss the World Table Tennis Championships, so the overall level of the World Table Tennis Championships is very high, and the difficulty of winning the championship is very, very large. The top players of the Chinese table tennis team may not have the opportunity to participate in the Olympic singles competition, but there must be a chance to participate in the World Table Tennis Championships, Houston World Table Tennis National Table Tennis won five men's singles and women's singles places, this is still obtained in the case of being reduced, the past World Table Tennis Championships National Table Tennis players to participate in the men's and women's singles quota is more, it is precisely because there are many national table tennis players to participate in the World Table Tennis Championships, so the overall level of the World Table Tennis Championships is far more than the Olympic Games, its difficulty to win the championship is very large, the former men's singles World First Marlene has never won the World Table Tennis Championships, Chen Meng, the world number one of the current national table tennis women's team, has also repeatedly missed the champion in the World Table Tennis Championships. However, the World Table Tennis Championships are held once every two years, although it is very difficult to win the championship, but the opportunities for competition are relatively large, if the hard power is enough, the probability of winning the championship in the World Table Tennis Championships is still relatively large.
Men's and women's singles World Cup has always been considered a chicken rib in the "three major competitions" of table tennis, the main reason is that the number of participants is limited, but also to take care of the qualifications of athletes from all continents, although the Olympic Games also take into account the wide range of athletes from all continents in the world, but after all, there are more places, and the World Cup men's and women's singles only have 16 places, Chinese players because of the "monopoly" of the Asian Cup and the World Table Tennis Championship and get two places, most associations have only one or even did not get the right to participate in the World Cup, In this case, the overall level of the World Cup is indeed very limited, may not be able to reach the level of a super platinum level open tournament in the past, for the national table tennis players, as long as they qualify for the World Cup, then there is a fifty percent probability of winning the World Cup championship, for the men's team players, for the women's team players, Liu Shiwen and Marlene have won the World Cup many times, but neither of them has achieved the "Grand Slam" cause.
