Here are some videos I’ve shot in Zhengzhou. Note the obvious influence of Fellini, Bergman, Hitchcock and Scorsese, not to mention “America’s Funniest Home Videos.” Among my subjects: a man doing tai chi with a sword, college freshmen doing military exercises, kids singing and dancing in Erqi Square, street food vendors skewering octopus and lamb, future Chinese hoop stars, a little girl blowing me a kiss, and my students laughing when I tell them they’re on camera.
