I recommend...
Love In The Forlorn CityIt's a romance melodrama, very sad, with main couple with great chemistry! Don't be put off by the too quick/forced start of their relationship, it gets more believable and the OTP CHEMISTRY really makes up for it. Oh, and there's NO annoying dubbing over their real voices either, unlike other C dramas!
Also its OST/Music is just WOW
Mysterious Summeran anthology series, aka different leads/story per each episode. Dark mystery/horror/thriller; unique and creepy oneshot stories.
Those are the only chinese dramas that I think are good (of the ones I've watched, nomally don't like C dramas).
