I've played in a lot of big matches and you learn from them.
I would prefer to have no money but to have a nice family and good friends around.
Nobody says if you hit No. 2 in the world you have to win all your matches.
Just because you win the French Open it doesn't mean you can do well at Wimbledon .
I'm still happy, I like this life.
China tennis - we're getting bigger and bigger.
