2015 Suzhou World Table Tennis Championships have closed. I have watched most of the competitions during the labor's day.Women's singles final give me a deep impression. In deciding game Ding Ling VS Liu Si Wen, at that time Liu Si Wen seems to be superior than Ding Ling and the game was intense. Unfortunately Ding Ling takes a ball failure as while hurt her feet. We all believe that the person must give up the game but, after 10 minutes Medical Time Out she came back to the game. Liu Si Wen and Ding Ling are the best friend and they live in the same room. No doubt she was influenced by it because obviously she was slowing down the game and she didn't play like before cunning and fiercely. She might be worried her feet will get more seriously hurt, The end Ding Ling was won. If it was a normally game, I believe Liu can win the game also if Liu is a heartless girl  she also can win the game. She can't regret and the result can't be changed.
