One of the most interesting places we saw outside of the EXPO was an Insect and Bird market. This place was really bizarre. More than anything, they had crickets for sale, which we learned the Chinese believe can bring luck. In the US when you buy crickets, you buy a cup full. Here, they sell them individually. Each cricket is in its own ceramic container. Before customers buy them they poke at them with a stick--I have no idea what this tells them.
They also have tons of giant locusts and plenty of bugs I've never seen before. There were weird turtles, exotic birds, giant fish, chipmunks, and squirrels. The place was packed. One guy told me I couldn't take pictures, but I managed to get a few.
