In the March Singapore Grand Slam tournament announced by the International Table Tennis Federation, the national table tennis team actually had only one pair of combinations to participate in the main competition in the mixed doubles event, that is, the mixed doubles champion Wang Chuqin /Sun Yingsha of the Houston World Table Tennis Championships, but the two were only ranked No. 2 seeds, and the 2019 World Table Tennis Mixed Doubles Champion Liu Shiwen / Xu Xin did not appear in the list of seeded players, to know that the two still ranked 3rd in the world ranking, obviously have given up the mixed doubles competition of this Grand Slam. For the two veterans, never qualifying for the Olympic Games has become a regret in the hearts of the two, to achieve such a goal is far more difficult than the London, Rio and Tokyo Olympic Games, the two are getting older, need to save physical strength, for the Paris Olympic Games or give up mixed doubles, focus on singles.
The top 4 seeds in Singapore's Grand Slam mixed doubles were Lin Yunru/Zheng Yijing in Chinese Taipei, Wang Chuqin/Sun Yingsha in China, Leibesson/Yuan Jiannan in France, and Zhang Benzhi and/Hina Hayata in Japan. Taipei combination is the mixed doubles third place of the Tokyo Olympic Games, the Chinese combination is the champion of the Houston World Championships, the French combination is the 4th place of the Tokyo Olympic Games, the Japanese combination is also the runner-up of the Houston World Table Tennis Championships, all of which are the combinations that remain in the forefront of the competition, the most likely to win the top 4 seats in this event, the most winning strength is still the national table tennis Wang Chuqin / Sun Yingsha, the two are currently ranked only 5th in the world rankings, and it is very promising to raise the world ranking to the top three ranks through the Grand Slam.
The layout of the national table tennis participation in the Grand Slam tournament is still focused on singles, the main lineup is out of the nest, even Xu Xin and Liu Shiwen, who have specialized in doubles in the past, have abandoned the mixed doubles project, focusing on creating good results in singles, improving the world ranking, and also adding convincing force to the competition in singles in the Paris cycle. The 31-year-old Xu Xin joined the main team of national table tennis from the London cycle, but there are not many singles championship titles, only the 2013 World Cup men's singles champion, the World Championship singles has not reached the final, and the Olympic Games have never qualified for singles. Xu Xin in the London Olympic cycle is still shallow, lost to Ma Long in the third person competition in the Olympic Games, and still can't surpass Ma Long and Zhang Jike in the Rio Olympic Games, and with the rise of Fan Zhendong in the Tokyo Olympic Games, Xu Xin once again participated in the team and mixed doubles competition as a third person. Paris cycle continues career, the only Olympic singles project that is not involved in, has become the target that Xu Xin most wants to break through, from the perspective of the Macao Championship, Xu Xin's competitive level still exists, but if he wants to suppress Grand Slam winner Ma Long and one of the world's 1st Fan Zhendong to get an Olympic singles qualification, Xu Xin must have a high probability of winning the world championships and Grand Slams in these two years.
Liu Shiwen is also 31 years old this year, as early as 2005, she successfully won the team's large round robin championship, with the major event champions, but unfortunately she won the world cup and the world championship women's singles championship, but the Olympic women's singles qualification. Liu Shiwen's singles results are significantly stronger than those of mixed doubles partner Xu Xin, but the internal competition of the Chinese women's team is more intense than that of the men's team, and there are stronger middle players in the strong, Liu Shiwen has repeatedly folded the Olympic women's singles qualification: the 2012 London Olympic National Table Tennis sent the previous year's World Table Tennis Champion and Runner-up Ding Ning and Li Xiaoxia to participate in the women's singles competition, in 2016 Liu Shiwen even if it is the top of the world rankings, still lost to the results of the competition, Ding Ning, Li Xiaoxia again participated, In 2021, Liu Shiwen won the women's singles championship of the World Table Tennis Championships in this cycle, but unfortunately the Olympic Games were delayed by one year, and she lost to the injury, and was later overtaken by Chen Meng and Sun Yingsha. Macau is a stop for Liu Shiwen to start again, the women's singles runner-up has a super high gold content, and the third and second runners-up of the women's singles of the World Table Tennis Championships in Houston have reached the final, proving that she is still one of the main players of the Chinese women's team, and Liu Shiwen did not lose at the starting point in the women's singles competition at the Paris Olympic Games.
