The most disturbing of all is that the stands across from these meat and fish stands are selling bread and other baked goods. Next to this, a stand selling really cheap clothes or candies. I will never, not that I have ever done this, buy bread at public markets in Taiwan (not that there's anything wrong with it).
Despite all of this, the meat and fish that you get from public markets like these are probably the freshest ones you'll get. At the same time, I can't wait to shop for food in an air-conditioned environment and still get really fresh meat and seafood.
