Once upon a time, someone went to visit a friend and saw that the chimney of the owner's stove was straight and there were firewood and grass piled up beside the stove, so he said to the owner: "Hurry up and change the chimney into a curved chimney, move the firewood and grass next to the stove, beware of a fire!"

The owner killed cattle and bought wine to buy banquets, and thanked the neighbors who put out the fire. He asked those injured in the fire to sit in the seats, and the rest arranged seats according to the size of the credit, but did not invite the friend who advised him to "relocate the firewood".

Someone said to the host: "If you had heard that guest, there would be no fire at home. Isn't it strange that you would not invite him to the banquet, but treat the injured person who put out the fire as a guest of honor?" The host then woke up and hurried to invite the friend.
