Follow the alley behind the Xikai Chruch with the onion domes and you will come to a wonderful pet market. Lots of fish and birds. In the winter you will see them pouring water from tea kettles into the aquariums to warm the fish. The portable pet shops on tricycles are cool too.
Unfortunately you can see many endangered animals for sale. Eagles, magpies, turtles, squirrels, etc. all of which are 'protected'.
