When Zheng Banqiao was working abroad, he left his 6-year-old son Bao Xiao at home, while his younger brother Zheng Mo was left unattended. Zheng Mo likes Bao Xiao very much. Bao Xiao often shows off: "My dad is a big official outside!" Sometimes Bao Xiao bullies other people's children. When Zheng Banqiao learned these things, he was very anxious and wrote to his younger brother: "I didn't give birth to a son until I was 52 years old. How can I not love? " But teaching is more important than raising. "He asked his younger brother to be strict with his children.
When Zheng Banqiao died (later, later and later), he called his son to the bed and suddenly offered to eat the steamed bread made by his son. When his son sent the steamed bread to his father's bedside, his father was already dead. Bao Xiao burst into tears with grief. Suddenly he found a note beside his father, which read: "Sweat, eat, do things and rely on your ancestors. Not a hero. " Zheng Banqiao taught his son a lesson on self-reliance before he died.
