On the very first day of buying a school district house in full, Teacher Shen was blocked at the door by his neighbor He Lijuan, who flung over a handwritten 70% discount transfer agreement. It turned out she had set her sights on this apartment for half a year, convinced it was already in her pocket. From then on, doorbells, emergency calls, and homeowners' group public opinion took turns, pushing the family to want to move away at a loss. But as a teacher, Teacher Shen knew better than anyone that giving in meant telling his daughter that rules must yield to scoundrels. He turned off his weakness, began keeping evidence and going through procedures, step by step turning this long-term harassment that didn't break major laws but only stepped on boundaries into the day the neighbor moved out herself.
