At the age of 25, I had just moved into a new home when I encountered unreasonable entanglement from Li Yingjun's family upstairs. Not only did they forcefully ask for a wedding fee, but they also asked to borrow a room to entertain relatives and forced her to be a bridesmaid. I couldn't bear the harassment and fought back decisively. I teamed up with my neighbor Xu Xin, who was also bullied, and with the help of my cousin Gu Ze who suffered from mania, I treated the other person in the same way. From the stereo to countering the noise harassment, to arranging for the other party to compensate for the hotel fees, to collecting evidence to expose his evil deeds such as spreading rumors, robbing property, cheating on his son before marriage, etc., In the end, Li Yingjun's family was ruined, punished by law and left the city in embarrassment, completely free from harassment.
