Zheng Sanjun, a young man from the rural areas of the Ming Dynasty, came from a poor family and depended on his mother for survival. On New Year's Eve, he bought a pig's head on credit to worship his ancestors for the New Year, but an arrogant butcher came to his door and demanded it back by force. Witnessing the local powerful gentry colluding with forces to bully the common people and attempting to forcefully occupy the academy's graveyard, Zheng Sanjun refused to let ordinary people be bullied arbitrarily. Relying on his extraordinary courage and resourcefulness, he cleverly devised schemes to fight against a group of villains, seeking justice for the grassroots villagers, and watching how an ordinary commoner stirs up the countryside and fights against the injustice of the world.
