In Shanghai, there's a park where folks get together to buy, sell, and talk about birds. It's not all birds, but that's what's mostly there. It's all Chinese men talking, spitting, squatting, and having a leisurely day. I'm not sure who comes to buy birds, but maybe it's for the seed or feed. I also saw worms and what looked like fat beetles (maybe it was for some kind of Chinese medicine?), then a few had antiques. I walked through twice since it was so interesting. I didn't buy a bird, but if I wanted one, this was the place.
