Well, while they are not to be trained to be models, which is totally correct, you have to care for your looking if you want to gain (more) badminton fans' favour. You may say that's pretty sketchy, but it's how people live and think. If you're good at something, you will be respected. If you're good looking too, you will be adored.Think that's a bit unfair on the rest of the players - men included.
They were not trained to be models but athletes.

Back to topic: So sad to see her not gaining another WC-title, since the WC-title she gained was with a partner she didn't like at all. I truly wish she had won a WC with Xu Chen. Without ZN and ZYL in their era, I'm sure they would have all the precious major titles.
