Do you know of Guo Degang? In recent months he has become well known in China as a crosstalker．He has never performed on TV before, but attending his crosstalk performance is becoming increasingly fashionable in Beijing, especially for youth and school children．

Guo arrived in Beijing from Tianjin in 1995 and came across a teahouse where he found several young people performing crosstalk．Being a crosstalker himself, he couldn’t help taking to the stage．Gradually, more and more people came to the teahouse to see him perform．He soon found himself playing to audiences numbering more than 100 in a teahouse that could only contain 80．

As his popularity grew, Guo thought over the future of his art．“Traditional crosstalk is at least half an hour long, but performances are no longer than five minutes on TV, which kills much of the story．TV is part of the fast-food culture and crosstalk is a face-to-face art form — it needs interaction (交流), and is not suited to TV,” Guo said．He decided to bring it back to its roots： the teahouse and theater．

In 1996, Guo and some young crosstalk actors founded Deyun Crosstalk Association．Over the next ten years, the association organized countless performances in teahouses across Beijing．Despite their growing popularity, Guo ensured (确保) that ticket prices were kept low to make the art form accessible to everyone．Tickets to his performances are still 20 yuan today．And in keeping with technology and modern times, the association set up a BBS site on the Internet where fans could download recordings and discuss performances with actors．

He hopes that through their efforts, more young people will learn to appreciate crosstalk and perhaps train to be crosstalkers themselves．
