Zhou Zhiqiang marries into the Zhang family and works tirelessly every day, only to be mistreated by his mother-in-law and wife. When the cooperative distributes 100,000 yuan in dividends, he receives only 250 yuan in wages, while his younger brother-in-law gets a fortune without doing any work. Facing contempt and expulsion, he quietly saves 3,000 yuan of private money and plans late into the night in the farm tool shed to lease and cultivate barren land. He firmly believes that hard work and innovation can open up new horizons, and those who once looked down on him will eventually be moved by his perseverance and growth.
