Through Uncle Ma's introduction, Biaozi meets Xiuer and discovers that she is struggling to make ends meet while raising her younger brother and enduring harassment over her debts. He voluntarily promises to take responsibility for repaying them. Determined to raise healthy fish in his pond, he sincerely seeks advice from an experienced technician and risks his life to collect Longyan grass. Through hard work and careful experimentation, he manages to raise fish that are both plump and delicious. Others try to copy his methods from pictures but take the wrong approach and fail. Biaozi keeps his promise, pays off the debt, and secures a long-term partnership with a restaurant. Together with Xiuer, he builds an increasingly prosperous life.
