Xiao Lin's private charging pile was used by Aunt Wang and her son Wang Bao upstairs for a long time. After being reminded, he was accused of being stingy. Xiao Lin locked the pile remotely and installed the monitoring system before going out. Aunt Wang secretly asked someone to remove the pile and connect the wires privately. The illegal use of electricity caused a fire and burned down the Rolls-Royce of neighbor Long Ge. Aunt Wang tried to blame Xiao Lin, but Xiao Lin used surveillance cameras to restore the truth. The court ruled that Aunt Wang was fully responsible for compensation of 680,000 yuan. In the end, Aunt Wang's house was auctioned, her son ran away, and she was so depressed that she became insane. Afterwards, Xiao Lin sold his house and moved. He realized that kindness requires sharpness and there is no need to condone greedy and selfish people.
