To buy his son a house and a wife, and help care for his newborn grandson, fishing king Wang Kun emptied his savings, sold his fishing boat, and gave up going out to sea. For ten years, he worked as a free nanny for his son and daughter-in-law. Who could have imagined that, after turning sixty, he would be forced by his own son and daughter-in-law to sell his home and thrown out of the house? A dolphin he had rescued ten years earlier returned to repay his kindness, giving him a black pearl. Wang Kun gained a miraculous ability to communicate effortlessly with all kinds of marine animals! With this extraordinary gift and his lifelong expertise in reading tides, identifying fish and reefs, and predicting the wind, he cut ties with his ungrateful family and turned his life around through beachcombing, rising once again to the peak of his success.
