I know it was around 1989. At that time, it was the township government that forced farmers to harvest the wheat that was about to mature and transformed the whole people to plant mulberry trees, which was euphemistically called "deep ditch hanging trough" "If you want to be rich, go and move mulberry trees! It was the slogan at that time. At that time, all the super-living people were kept in the township government, and they were released when they paid the fine. . . . . . . . . . .
