Shen Haizhu, once the King of Fishermen, sold his boat and retired to raise his son. But on his fiftieth birthday, his son and daughter-in-law humiliated him relentlessly and forced him out of their home. Heartbroken, he returned to his fishing village and drew on the fishing skills he had honed over decades, starting with beachcombing and diving before buying a boat and heading back out to sea. Step by step, he reclaimed the heights of success. Facing ridicule, schemes, and demands from his greedy relatives, Shen Haizhu refuses to endure their mistreatment any longer. He reclaims his dignity through his own abilities and proves that fifty is never the end of life, but the beginning of setting sail once more.
