When I was in China in 1980 I saw some amazing things. I was in Canton (a fairly large city). A man was walking down the street with honey buckets. They didn't have indoor plumbing and used the human waste (collected that morning) to fertilize their crops. I also saw a poor skinny chinese man with a huge hog (must have been 600 pounds) strapped to a wheel barrel he was taking to market. Market was a few miles away.
