When Tie Pao was little, he fell into a river and hit his head on a rock, leaving him with an intellectual disability. He thought he was destined to spend his whole life herding cattle.

But he went on to start a business and lead the villagers to prosperity, making them all see him in a new light. At last, Tie Pao got his moment in the spotlight.
