Dressed in a neat blue blazer, grey slacks and a crisp white shirt with a red-striped tie, the man sweats as he moves back and forth on the stage, waving a small booklet in his hand. He's shouting English, working the crowd, pumping it up, part preacher, part motivational speaker, and part stand-up comedian. The crowd of hundreds shouts back on signal, at the same time waving their hands in the air.
This is no southern Christian revival. Li Yang, the man on stage, has become something of a legend in China for having a big mouth, and he is in Chaoyang Park to promote his trademark Crazy English, based on the belief that shouting helps you to concentrate and remember better.
