I think players changing coaches is normal.
I've played in a lot of big matches and you learn from them.
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 don't know how many years I can still play. I have to listen to my body and see how it feels.
