Liu Shiwen is a domestic and even international first-class athlete, although not the top, but definitely the top.

And those who don't like her, often come up with the two games, are the major defeats suffered by the Chinese team for more than a decade.
The first match, of course, was the 2010 Women's World Table Tennis Championships, when he alone lost two points, leading to a 3-1 defeat to Singapore and a loss of the championship. The other was the just-concluded mixed doubles final of the Tokyo Olympics, in which he and Xu Xin lost to Ito and Hayabusa Mizutani in the final, losing 3-4 to Gold.
But privately, Liu Shiwen is certainly responsible for the failure of these two games, however, the main responsibility for these two games is actually not Liu Shiwen.
First of all, let's talk about the Moscow World Table Tennis Championships, the Moscow World Table Tennis Championships lost, Liu Shiwen lost two points by herself, although it is a heavy responsibility, but the main reason is because of the problem of head coach Shi Zhihao's platoon.
At that time, Wang Nan and Zhang Yining had already retired, and Shi Zhihao and Guo Yue, Li Xiaoxia were a bit contradictory, and it was also common for people not to let them play. But the ball always has to be played, and the people always have to be sent. In order to cultivate newcomers and his direct family, he chose Liu Shiwen and Ding Ning, and the final result was that the gold medal was lost.
However, here we must also point out Liu Shiwen's shortcomings. The two games were lost to Wang Yuegu and Feng Tianwei respectively, and Ding Ning also lost to Feng Tianwei. And at this time, the Singapore team is actually no longer at the peak, in 2009, Li Jiawei, who had eliminated Wang Nan, was already married and retired, in fact, only Feng Tianwei could bear the banner.
Then, losing to this veteran opponent with rich experience and strong technical tactics is reasonable, but Liu Shiwen's loss to Wang Yuegu is really impossible to say. Because Wang Yuegu was 30 years old at that time, he belonged to the third-rate players who were not ranked in the top ten in the world rankings, and had never entered the top four of any world-class singles competition. But Liu Shiwen faced such an opponent and lost.
Here to say, not to Guo Yue is still a bit reasonable, in addition to the contradiction, Guo Yue in 2006 and 08 consecutive World Table Tennis Championships team lost. Shi Zhihao, who had been bitten by a snake, couldn't believe that Guo Yue could understand it, but at least Li Xiaoxia or Guo Yan should make a single, not use Liu Shiwen or Ding Ning.
The second match, of course, was the mixed doubles final of this year's Tokyo Olympics, and she finally lost to Ito Mimachi and regretted that she had won the silver. I don't know if it is the reason for marketing, or whether netizens really think so, the Internet is full of scolding, are talking about Liu's problem. But mixed doubles are basically girls organizing the ball path, boys are responsible for the attack, male players dominate, and female players assist. Liu Shiwen has her own problems, but Xu Xin is not without problems, then in the case of the same problems, shouldn't Xu Xin take on greater responsibility? In other words, if the mixed doubles really won the championship, everyone would think that Liu Shiwen and Xu Xin had a greater contribution?
Everyone may have athletes they like or dislike, but hopefully we can be more objective in evaluating them.
