If you are fortunate enough to travel in China, I want to encourage you to keep your eyes open: you never know what you might see! While visiting one city near a mountain many people like to climb, I saw how, when it is time to harvest the wheat, local farmers will spread the wheat on the road, dirt or paved, and let the traffic thresh the wheat. I had never seen that done before, but it made sense to me. As I got closer to the mountain, I was walking down a dirt alley and came across another way to process the wheat. This stone wheel made me wonder how old it was and how hard it must be to manually move the wheel over the wheat. I think I have seen a larger one of these before; it was large enough to use a horse or donkey to make it work.
