Zhao Mingyuan's family bought a new home. Because neighbor Sun Liping failed to purchase the apartment at a low price, she constantly harassed them by ringing the access control at midnight, frightening their five-year-old daughter. She also resold access cards, forced them to sell the apartment at an 80% discount, and edited videos to complain about the school. Zhao Mingyuan kept evidence such as recordings and logs, and teamed up with the property management and tenants to clarify the truth. In the end, Sun Liping and her husband made a public apology and promised to stop the harassment, allowing the family to safeguard their home.
