It’s not often you get to sit down and talk with a real, living national treasure, especially in their living room. But that’s exactly what I had the opportunity to do a few weeks ago when I visited the home of Lin Yuezhang. Mr. Lin is a master of budaixi, a sophisticated form of puppet theater with deep roots in Taiwan. Mr. Lin’s family has now been performing budaixi for four generations. But he says his generation will be the last. And, he says, his isn’t the only performing family calling it quits. Today, Mr. Lin takes us on a tour through the world of budaixi and explains why he thinks it is a threatened art form.
