Cheng Fei actually skipped three years of competition between 2009 and 2019 to rehab the ACL. (I believe she tore during a training session for the 2009 National Games.) In 2012, she participated in a World Cup and maybe one national event before she ruptured her Achilles in training right before the final Olympic selection. Before that final, career-ending injury, she looked pretty good. She wasn’t doing full difficulty on V or FX, but she certainly would’ve contributed on both events in London.
On a side note, the Chinese media has been incredibly cruel to Cheng Fei since she retired. She’s been the subject of countless articles and TV pieces with titles like “Former Olympic Champion: Over 30, single, and fat!” (Never mind that she’s a very good coach who holds a Masters degree in sports science.)
In response to
@ArnoldRimmer, the Wang/Xu gymnasts aren’t necessarily weak on V/FX. Wang Yan came from this group, and so did Yao Jinnan, who competed a DTY throughout her career and also had a double layout on FX. On the whole, though, Wang and Xu do tend to produce UB/BB specialists who struggle on V/FX–Huang Huidan, Liu Tingting, Li Shijia, and Ou Yushan. The real issue, though, is that their gymnasts are constantly, repeatedly, serially injured–hence the MLT analogy. Li Shijia and Ou Yushan are the most recent casualties. I’m legitimately (if pleasantly) surprised that Guan Chenchen was healthy enough to win a gold medal in Tokyo. Let’s just hope that Coach Wang makes good on his promise to retire now that he finally has an Olympic champion.
As to the larger question of what China should do now, I have no idea. I’m as disgusted and baffled as everyone else here.
