     Crosstalk, a traditional form of comic storytelling, is making a comeback in China's teahouses and

theaters.

     Audiences can laugh the night away every Saturday at the Qianxiangyi Teahouse in Tianjin,

entertained by the apprentices (学徒) of Hou Baolin, Ma Sanli or Yin Shoushan -- all leading crosstalk

artists of years past -for only 20 yuan (US$2.40). The success in Tianjin has also given motivation to the

rejuvenation (复活) of crosstalk in Beijing and other places.

     Although the art form originated in Beijing in the Qing Dynasty (1644-1911), Tianjin became a place

where rising stars developed their styles and new pieces were tried out. The city was famous for the

quality of its crosstalk performances.

     "We only want to bring the traditional pieces back to the audiences, helping them to learn their charms

and definitions," said Yin Xiaosheng, head of the Zhongyou Arts Troupe.

     Known in Chinese as xiangsheng (literally, "face and voice"), crosstalk was the main form of comedy

throughout most of the 20th century. In the old days in Tianjin and elsewhere, temple fairs and markets

were the main places for crosstalkers to perform, although they occasionally also appeared in teahouses

or theaters.

     Usually crosstalk pieces draw on every aspect of Chinese culture, from history and folk tales to

contemporary social issues. Although there are hundreds of pieces in the traditional works, they are

constantly rewritten to suit the times and the audience, while new works are written as well. This is one

of the features that have made crosstalk a populist(平民化) art form throughout its history.

     "Crosstalk was in the doldrums with competition from other art forms, especially TV," said Wang

Xiaochun, headmaster of the Northern Storytelling Arts School of China (NSAS). "But it has regained

its status with crosstalk fans, especially young people, growing aware of its rare qualities." The

reawakening of interest in the traditional art is going beyond merely watching and listening for many.

"More and more students are coming to NSAS to study crosstalk, including some girl students," said

Wang, "They are sure that crosstalk will have a strong market."
