A farming couple head to the city to make a living, and through their own hard work, eventually settle down there.
Because they married during a famine, her in-laws resented having another mouth to feed. Zheng Shuang'er felt she couldn't get along with the family, so she followed her husband to the city. At first, she only wanted to get pregnant sooner, but unexpectedly found work there. So she and her husband settled in the city. Life in the city broadened Zheng Shuang'er's horizons and unexpectedly opened her eyes to a business opportunity.
City folk saw things differently from country folk. They no longer valued things that were still perfectly usable, but for poor people in the countryside, the items city dwellers threw away were treasures. Zheng Shuang'er collected discarded goods from the city, gave them a simple touch-up, and sold them in the countryside. With this way of making money, she and her husband eventually settled down in the city, becoming the envy of everyone as city folk.
