Driving school instructor Zhou Cheng legally purchased a property-right parking space in the residential complex, but neighbor Sun Li had occupied it without compensation for a full eight years. Sun Li had long taken this convenience for granted, and after Zhou Cheng refused her proactive request to buy it, she frequently came over to harass him and deliberately made things difficult for him everywhere. Sun Li also relied on her husband Zhao Qiming's property management status, abusing management privileges to create obstacles for Zhou Cheng everywhere. Facing the step-by-step advancing neighborhood conflict, Zhou Cheng did not impulsively argue, calmly retained all evidence, and guarded his own legal property with legal principles.
