Once upon a time, there was a rich man. Before he died, he said to his two sons, you two go to chop wood and see who cuts more and faster.

Early in the morning, the eldest son went up the mountain with a knife to cut wood, and the second son sharpened his knife and left.

In the evening, the second son cut the most.

The rich man saw it and said to his two sons, give the property to the boss, because the second one is so capable anyway!
