An orphan, Lin Haisheng, acquired exquisite fishing skills. After starting a family, he shouldered the heavy burden of the entire household. His father-in-law and brother-in-law were idle and lazy, leaving the entire family's livelihood pressed upon him alone. Sympathizing with his wife, Su Lan, every time Lin Haisheng returned from the sea, he handed over most of the money earned from catches while being extremely frugal with himself. However, after Su Lan got acquainted with a fish merchant, she gave birth to other thoughts, growing increasingly cold towards him, and her family constantly forced the two to part ways. Completely disheartened, Lin Haisheng chose to let go and divorce, setting sail alone to venture forth with his solid skills, carving out a career and becoming a renowned captain far and wide.
