A farmer was going to die. He wished to show his sons the best way of farming. So he called his sons to him, and said to them, "My children, I am going to die. I leave something for you. They are in the yard."

The sons thought perhaps there was some treasure in the yard. So as soon as the old man died, they began to work with their spades and ploughs. They turned up the soil over and over again, but they didn't find any treasure.

However, in this way, the rice grew faster and better than ever before. And the sons got much more money.
