Originally thought that the Arnold River would be clear and bottomless. As a result, it was very yellow and muddy. People in the same trade also joked that it was from the Yellow River. But the local people don't seem to care very much, because there are people who are ready to practice rowing on it. The tour guide said it was because of the rain. I'm not sure. You can see the Arnold River from the Uffiz Museum of Art, and you should be able to see the oldest bridge in Florence.~
