In the 1970S, I Worked on Solving Crimes in the Neighborhood Committee.

In 1975, Mai Xiaoman became the youngest neighborhood committee mediator in Chunfeng Street. On her first day on the job, before she even stepped through the door, she was splashed with foot-washing water - two aunts fought each other in the street over a chicken, and onlookers blocked the alley. In the chaos, she picked up a household registration book that fell on the ground, and a mysterious system called "Neighborhood Archives" suddenly activated. This system does not provide a mall, and there is no force bonus. The only function is: when she touches the archive items related to someone, she can see several broken keywords and vague fragments of past events. The key words in the chicken theft case are "chicken feathers, cigarette butts at the front door, and dog holes." Mai Xiaoman followed the clues and found that there was another person who stole the chicken - a fourteen-year-old boy who stole the chicken to collect travel expenses to go to the northwest to find his educated youth sister who had been missing for three years. This is just the beginning. In the days that followed, her mediation diary was filled with all kinds of "trivial matters": the model husband stayed out at night, the textile factory was haunted in the middle of the night, the old lady living alone had her food books stolen... Each of them seemed to be a common occurrence, but the file fragments were like a puzzle, each piece pointing in the same direction - A person named "Lan". On a rainy night in 1967, three people died in the culvert of Chunfeng Street. The truth was buried for eight years. And those "little things" are never trivial.
