Chen Mo parked his car in a parking space owned by his family. In the early morning, he received more than 80 calls from the property management to urge him to move the car. He could not bear the harassment and turned off his phone to fall asleep. Early the next morning, he was surrounded by more than 50 angry property owners in front of his home and learned that there was a trace of red under the parking space. Everyone accused Chen Mo of being selfish, and the property management company also shifted the responsibility to him. Chen Mo discovered that the "red traces" smelled like paint and insisted that they were not blood. When he refused to move his car and asked to find out the truth, can surveillance reveal the mystery of this incident?
