Aside from like the first ep, Cuo Dian Yuan Yang is pretty light hearted and goofy, I enjoyed it and recommend.
I never finished Legend of Lu Zhen since the male lead and second female lead started getting on my nerves. Zhao Liying was great in it, and I might finish it, eventually. It's a little different from a lot of palace dramas since she isn't in the harem, so that's something to look forward to.
I liked her character in Rookie Agent Rouge but I also never finished it (I have so many shows on hold). The male lead is also pretty annoying, but up to the ep I stopped at, they haven't fallen in love yet so it was expected.
I remember being upset at the male lead in journey of the flower but I don't remember why lol.
Generally speaking I've dislike most of the male leads in her dramas. Not the actors, just personalities of the male leads, but that has nothing to do with her.
