Fu finds a reason to restore her winning smile

With injury casting a shadow over her career, Fu Yuanhui was not her usual chirpy self at the start of the national championships in Taiyuan.

The 22-year-old has become a celebrity in China after her emotional post-race interviews at the Rio Olympics stole the nation's heart, with her colorful personality, witty social-media posts and reality show appearances building her a huge following outside the sport.

However, the beaming smiles from Brazil were replaced by a heavyhearted demeanor on Friday at the ongoing nationals thanks to a nagging left shoulder injury.
