Are any of those on netflix? I know the untamed is and I considered watching itI´m so happy! He is a singer, an actor, a model and a graphic designer. I prefer him as an actor more than a singer, though he does have a very beautiful voice that is suitable for ballads!
I´d recommend The Untamed as it is really a wonderful show with a lot of character development and it is very beautifully shot.
But you can also see him in the Jade Dynasty, Oh My Emperor! (it is such a lovely show as well) and Joy of Life.
Oh my Emperor, the Untamed and Jade Dynasty are fully published and with English subtitles on youtube!!
Also, here is to make you laugh a bit :D
