I dunno, seems to me Xiong's been growing a little less wonderstruck as the series moves on. But I can see what you mean.
I think my perception of Andy Lau is firmly grounded in the gambling movies he did and then recently his performance on stage as a singer.

I haven't watched anything by this guy, so I can't say. Besides, I don't have a very good image of what Xiong is like, and I rarely picture the characters when I read.
