In some places, rivers look more like canals. Pollution, garbage in the water, old wooden houses can be seen everywhere. There are also some river markets. Frankly, these rivers are far from meeting the standards of the Amsterdam or St Petersburg canals. River markets are very common in Africa and parts of Asia. I was interested in canals when I first saw floating markets in the 1980s. But now, I have gone to so many places that I think it is no longer interesting.
