After Lin Zhixia and her family moved into their new home, their next-door neighbor Su Huizhen repeatedly harassed them by ringing their doorbell late at night after her request to buy their house at a low price was rejected. Having sought help from property management and the police multiple times with little effect, which left her daughter terrified, Lin Zhixia calmly collected all relevant records, purchased compliant security equipment, and resolved to face the ongoing harassment head-on through reasonable and legal means to protect her family and life.
