"Nasty for them was just like really tame for (the West)," says Irish-American comedian Des Bishop. "The nasty show was actually one of their biggest shows for a while and quite a good atmosphere because it relaxed people, and they could talk about whatever the hell they wanted.

"They are still a little trapped with this feeling that these things are unacceptable to talk about. Not so much in terms of trouble - obviously there are other topics that you can't talk about - but they are hugely judgmental around things that are considered a little low, a little base."

Bishop was born in the US but has lived in Ireland since he was a teen, and is one of Ireland's best-known comedians.

A year ago, he moved to Beijing, film crew in tow, to shoot a TV series in which he learned Mandarin with the aim of performing a stand-up comedy routine within one year. That mission is complete - the show will air on Irish television later this year - but Bishop is reluctant to return home, having now found himself immersed in what he says is an exciting Chinese-language stand-up comedy scene.

"Not only are they new comedians, they are new comedians without having had anyone to base their stuff on, you know, they are literally like pioneers just taking this little hop. Some of them got into English-language stand-up and now they are trying to get into Chinese. It's pretty incredible," Bishop says.

"When I came here, all the talk was about how people don't understand stand-up comedy culture. Already that talk has dissipated in 11 months, and now the talk is, how do we expand this? More and more people want to see us. So things develop fast in China when they develop."

Bishop says not only are the audiences growing in number, but the skills of the local comedians are also improving as they get more opportunities to hone their craft.

"These guys are starting to experience success. Some of them are starting to have really good gigs," says Bishop.

"Culturally, shock comedy is not going to fly here, which is absolutely fine - there is absolutely no need for it. Whatever they find funny, they find funny. But I do think that you can see them getting more and more confident about the subject matter while maintaining a sense of not getting too crazy because you can get in trouble.

"There is a sense that they enjoy the freedom that (stand-up comedy) can provide."
