After her father passed away, Qinghe only received a thatched shed and a withered tree. She firmly remembered her father's last instructions: the tree drops copper coins only to help in emergencies and repay debts, and they must not be used privately. Facing her uncle's bullying and seizure, Qinghe held fast to her original intention, using the copper coins to clear old accounts for the villagers, and also uncovering the past stories of her father saving people, borrowing debts, and repaying kindness. Greed turned the copper coins into black stones, and also made her uncle repent and return to the right path. He returned the land deeds and food, repaired bridges and paved roads, making up for his mistakes with actions. After the money tree completed its mission and withered, Qinghe was elected village chief, turning the tree trunk into a public accounting desk so that honesty, gratitude, and responsibility are passed down from generation to generation.
