Like others said it's the director's choice. WC didn't hold back in kissing with Zhao Liying in Mystic Nine.
If you like period drama, I think "Love Lost in Time" is good. For modern action drama, "Age of Legends" is good. Both have happy endings. For Republican era with some action and tomb raiding adventure, "Mystic Nine" is good. It has open ending, but there will be a second season. He wore a lot of general costume in that show and I think his best look. I agree that Novoland is his best work so far.
