On a late summer day in Beijing while roaming through the narrow alleyways of an old pet market I heard the chirping of insects. It was such a refreshing sound on a stiflingly hot day. At one point, the chirping grew louder and louder, and my curiosity led me into one alley. There, I found countless little insects in bird cages and small jars on sale and waiting for their new owners.
