An old man and a young man were selling apples on opposite sides of a large tree. The old man's apples were large and red, while the young man's looked good, but many had wormholes. Since the prices were the same and the old man had a kind face, customers gradually flocked to his stall. To sell more apples, the young man lowered his price and rearranged the apples, showing only the best side to customers, which indeed attracted many more. After finishing their business, the two took a ferry home together, and the young man again tried to take advantage of the old man. The ferry was interrupted by a sudden wave, and the two men and the boatman fell into the water. The old man, finding his money bag too heavy, threw it away, but the young man, seeing this, risked his life to retrieve it.
