Li Yu Chun is a female singer, right? Sorry, I'm not very familiar with her. I search the internet and found this. http://en.wikipedia.org/wiki/Li_Yuchun . She's the one ZJZ planned to cast as Jia Bao Yu?
Btw, my personal choice for Jia Bao Yu is Kenny Kwan. Ok, he's not the best actor out there, but he looks the part. If Jay Chou can do it, so can he.
