The heroine Lin Man has long suffered verbal bullying and vandalism from a neighborhood group headed by Sister Lan due to parking problems. Her well-intentioned "S-shaped" parking method to reserve turning space for neighbors was maliciously misinterpreted as "poor technology." After ineffective communication and disputes with the property management company, Lin Man decided to sell the parking space. She specifically sold it to a former traffic planning engineer who was extremely particular about rules. Qian Gong parked his car in strict accordance with the standards, causing the vehicles of 12 neighbors who had illegally occupied the "fire evacuation passage" for parking for a long time to be completely blocked. Lan Jie and others subsequently used threats, harassment, moral kidnapping and other methods but failed, and Lin Man and Qian Gong won the final victory.
