Name of Chinese drama? Two girls get switched at birth?

Nancy Asked: Name of Chinese drama? Two girls get switched at birth?

Hey, I was wondering what the title of a Chinese drama was. I've been looking for it everywhere & haven't been able to find it. Anyhow, I watched it about three years ago. The movie is about two girls who get switched at birth in a hospital. One of them is a from a rich family while the other is poor. The poor girl's mom is in prison & at night she switches her baby with the wealthy one for a better life. Years go by & I think the mom in prison dies so the poor girl (originally supposed to be the rich one) moves in with her uncle & aunt. However one day, the rich girl (originally supposed to be the poor one) finds out that she doesn't have the same blood type as her parents. Long story short, the mother finds out who her real daughter is (this is when the two girls are still young) but can never tell the poor girl who is originally her real daughter because she ends of drowning at the beach trying to save her real daughter. It's a tv series and it basically follows the lives of the two until they're older. I would appreciate if you could tell me the name of the show? Thanks! P.S. no, I'm not talking about Autumn in my heart!
