The ancient Chinese had many accomplishments in agriculture too. They invented the iron plow, which was pulled by a bull or a water buffalo. They also invented the rotary winnowing fan, a machine used to separate grain. They also made the first wheel barrel, which looks pretty much the same as the ones used today. They harvested silk, and they kept this secret for hundreds of years. They invented the cast iron and many other things.
