"I passed by director Zhang at a karaoke bar, where he was talking to someone on the cellphone about this film. I'd always wanted to work with him. So when I got back, I asked my assistant to contact him," Wang said Saturday while promoting the film at the Shanghai International Film Festival.

In the film, Wang plays a deaf-mute girl who is crazily in love with an amateur car racer.

Zhang said he decided to cast Wang for the role when he saw her for the first time. "She has the quality."
