Nirvana in Fire - the BEST cdrama. I mean, the BEST SHOW EVER. its historical, some wuxia martial arts without to much fantastical, awe-inspiring narrative, riveting acting, not much romance. This drama is like the chinese version of Alexander Dumas's 'Count of Monte Cristo'. The plot has so many twist turns stops and surprises. That is what made this drama oh so good cause despite all the turns and twist the narrative was just sooo fluid. This drama is Simply the best ever. THE. BEST. EVER.
I also second Battle of Changsa. Its a period drama with no wuxia but oh so good. Wallace huo at his best.
Ten Miles of Peach Blossom - full on romance wuxia epic fantasy cdrama. Deals with dragon people, foxtailed people, water people and all other chinese folklore being and their lives in the fntasy alternate world.
The Disguider - another period drama, but oooooh so good. This was the drama that super made me fan of Jin Dong (loooopve him). Such awesome espionage and war drama.
Bubu Jingxin - this is the original adaptation of the korean drama Scarlet Heart that is based from the writing of Tong Hua. Its a historical drama with elements of wuxia and fantasy. UI certainly improved in her acting choos as compared to her previous works, she doesnt compare to Cecelia Liu. And Nicky Wu was soooo mesmerizing.
Go Princess Go - if you want super ultra silly fantasy wuxia history setting drama. This is the one for you. Laugh out loud drama with super crazy plot and scenes. This one is like a all things weird sitcom that somehow was addicting.
