The Myth is an obscure one but is quite different from the typical historical/romance, watch at your discretion.
+1 Legend of Lu Zhen
If you don't mind historical drama set in the 1900s, try Lady & Liar, I liked it more than Cruel Romance, feels more romantic. There's also The Disguiser, which was thrilling.
Noble Aspirations was decent, heavy on fantasy/wuxia, if you like that.
I usually don't usually suggest this (it's usually the other way around), but I recommend, if you're ever having trouble finding a good chinese historical drama, try looking towards sageuks, Empress Ki/Moon Lovers are big ones.
