Lin yuelan smiled faintly and said, " Uncle, you only see the part about it that is expensive, but not its value? For example, the weather. We all know that the weather is hard to predict. It might be sunny today, but it might rain tomorrow. It might rain for a few days at once. If you don't thresh the cut rice and let them pile up, I believe you know what the consequences are.
"As a result, the grains would sprout and grow moldy. In this way, half a year's hard work would be in vain. Not only would it be in vain, but if the tax was not paid, the whole family would have no food, right?
"However, with this threshing machine, as long as you harvest the rice on the same day, you can completely thresh it. Everyone, look at my family's five mu of land. I can confidently tell everyone that in just one day, all the rice can be threshed, and tomorrow, all the rice can be pulled out to dry!"
