Lu Zheng and his daughter just moved into a new home, only wanting to live a peaceful life. But their neighbor Liu Lihua set her sights on his apartment—ringing the doorbell late at night to disturb the residents, intensifying her behavior after being warned, directly showing up with a contract the next day to forcibly buy it, making a scene and blocking the door every day after being refused, and even running to the school gate to block the child. From late-night doorbells to daytime door-blocking, from insults to harassment, she crossed the bottom line time and time again. Lu Zheng exercised forbearance at first, until his daughter was too scared to go out. He no longer holds back. Recordings, videos, property management, the community office, and the police station—step by step, he puts all the evidence out in the open.
