When Zhang Wei, a 35-year-old truck driver, was transporting 20 tons of industrial lime powder, villagers mistook him for flour and robbed him. He was beaten when he stopped him. Zhang Wei warned many times that lime powder is highly alkaline and highly toxic. Subsequently, villagers were injured one after another due to the misuse of lime powder. After the incident, Zhang Wei, who was originally the victim, was accused of "poisoning" by the villagers. He was also investigated by the police for suspected negligence causing death, and was in a desperate situation where he could not explain himself.
