Around 2020, Lin Weidan spent his entire life savings of 600,000 to contract a barren pond for shrimp farming, aiming to help his debt-ridden younger brother make a comeback. He took charge of all core work including funds, technology and sales, while his brother and sister-in-law only guarded the pond. After the shrimp pond became highly profitable, his sister-in-law Tian Xiuqin persuaded his brother to force Lin Weidan out of the partnership on the grounds of principal settlement. With solid evidence including contracts, account books and orders, Lin Weidan cleared accounts thoroughly, exposed the core value of the shrimp farm, counterattacked the betrayal, and finally established a breeding cooperative. He perfectly interprets the truth: dirty pond water can be cleaned, but a greedy heart needs a complete change.
