The story is about a peasant couple who went to the city to seek a living, and finally settled down in the city through their own efforts.
Because she got married in the year of disaster, her husband's family disliked the extra people in the family. Zheng Shuang'er felt that she couldn't get along well with her family members. She originally followed her husband-in-law to the city just to get pregnant faster, but she accidentally found a job in the city, so she lived with her husband-in-law in the city. The days in the city made Zheng Shuang'er gain a lot of knowledge, and she also unexpectedly saw a glimmer of business opportunities.
The eyes of the city people are different from those of the country people. Things that are still usable can be looked down upon by the city people. For the poor people in the countryside, these things that the city people do not need to throw away are treasures in their hands. The scraps collected from the city people were simply processed and then sold to the countryside. Zheng Shuang'er relied on this way of making money to settle down in the city and became the envy of everyone in the city.
