Ew...Okay, I'd prefer for Du Chun to play 21 than for Mickey He to get anywhere near Tong Hua adaptations in general, lol.
I don't know much about Yun Ge's character but I like Zheng Shuang so I wouldn't mind her leading. I've heard really good things about her in Painted Mural (I haven't watched it, though) but it sounds like she has a lot of potential out of the 90's actresses. I don't know much about Zhao Li Ying so I only associate her with New HZGG, which probably isn't exactly a good thing, lol. But I know next to nothing about her so I'm neutral towards her.
