Eternal Love of Dream (Xianxia) ( Three Lives, Three Worlds, The Pillow Book) - this is beautiful and cute and tells the story of Bai Feng Jiu and Dong Hua (from Eternal Love, where they were side characters) right, according to novels. Their story in Eternal Love was mostly made up, because they didn't have licensing rights for the Pillow Book, where their romance story happens.
Both dramas are standalone, so you don't need to watch them in right order.
Joy of Life (Wuxia) - very good drama with very strong ML.
Your Highness (Wuxia) - mostly comedy and parody with slight romance. ML becomes trapped in a game. It is really funny and ML is extremely strong.
Fights Break Sphere: Season 1 - just to mention, that there is also 3rd genre Xuanhuan. It is like Xianxia, but without immortal beings and more focused on adventure.
