After four knee surgeries and hundreds of shots injected into my knee weekly to alleviate swelling and pain, my body is begging me to stop the pounding.

I don't know how many years I can still play. I have to listen to my body and see how it feels.

Tennis is best of three sets, so even if I lose the first set, I still have a chance.

In badminton, they use a lot from the wrist. But I use a lot from the shoulder.

I just follow my heart.

I think because I was the first Chinese player to win a grand slam, people were thinking: 'She's not like normal people.'

I need some time to recover. I'm not a machine.
