Sometimes when you walk around at night in Taiwan, you’ll hear this strange percussive noise coming from people’s houses. It sounds like a lot of small, hard things colliding with one another. Now you’d be forgiven for thinking that everyone has rock collections, and that they take aggressively good care of them: moving them around, and even washing them. But those are definitely not rocks. 

I’m Andrew Ryan and in today’s Ear to the Ground, I bring you into a little hut behind my friend’s house, which is used exclusively for people making that clacking noise.
