One day old Mrs. Chang in the village got a letter. It was from her son Chen, who lived far away in Beijing. She could not read, so she waited in front of her house for someone to come by who could read out the letter to her. After some time, Warrior Wen came by, swinging his exquisitely carved staff. Old Mrs. Chang stopped him and said, “O brave warrior, could you do me a favour and read out this letter from my son to me?” Warrior Wen immediately agreed.
