Lin Jing has continued to pay the heating bill for five years, but her neighbor Wang Guifen has been paying for the heating all year round, and even laughed at her for being stupid because she has too much money. Unable to bear it, Lin Jing spent 30,000 yuan in the summer to install an insulation layer on the entire house to completely block heat conduction. When winter came, Wang Guifen's home had no heating and the water pipes froze and cracked many times. Instead, she came to the house to claim compensation, and even let her son harass and threaten Lin Jing. Lin Jing collected evidence and exposed her true face in front of everyone. In the end, Wang Guifen and her son were discredited and had to pay for the losses, so they had no choice but to sell their house at a low price and escape.
