I always had a powerful serve. It's one of the best in women's tennis. It's very good to have a weapon like that.

Writing is like a mental masturbation to me.

If I didn't do well at Wimbledon maybe Chinese people will forget about me.

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

China tennis - we're getting bigger and bigger.

What I've accomplished for myself is beyond my wildest dreams. What I accomplished for my country is one of my most proud achievements.

I just follow my heart.
