Ok right then, well the actor that I’ve decided to talk about is Zhou Xingchi, who, I think it’s fair to say, is one of the most famous and popular comedians in China.
You know, I’ve watched his films ever since I was a child, which I’m sure could also be said for the majority of people my age in China. And the reason is simply that he’s just so incredibly funny. I mean, whenever I watch his films, I can’t stop myself from laughing. And I’m not sure if you’ve watched any of his films before or not, but I guess you could compare him to Jim Carrey, in the sense that they can pull really funny faces. And that’s probably what sets him apart from most other comedians in China. You know, he’s got such an array of different facial expressions!
Anyway, as for what kind of person he is, well I don’t know him personally of course, but the impression I get of him is that he’s a very down-to-earth guy. So you know I mean, although he’s, like, super famous and mega rich, he seems to carry himself in a very unassuming manner. For example, in the interviews I’ve seen of him, he comes across as being a very modest and likeable guy, which can’t be said for a lot of celebrities you see on TV these days!
So yeah, that’s pretty much all there is to say really, and if you haven’t seen any of his films before, then you should definitely watch one.

I think I’m right in saying that he also wrote and directed some of the films he’s been in.
So he’s incredibly talented, and I think you can kind of tell when you see him in films that there’s something special about him., but it’s hard to say exactly what it is!
