Where is Dongguan Sandao Man from?

Guizhou people. It was reported in February 2023 that on February 13, 2023, at the entrance of an electronic factory in Shangjiao Community, Chang 'an Town, Dongguan City, Guangdong Province, the criminal suspect Yin Moumou stabbed three people with a knife, two of whom had no vital signs on the spot, and another 1 person died on the way to the hospital. The perpetrator Yin Moumou, 38 years old, from Guizhou, is unemployed and has worked for many years. Due to personal grievances, I asked Zeng Moumou (male, 32 years old) for a statement. During the period, Zeng was stabbed with a knife that he carried with him. Zhang (male, 29 years old) and Wei Moumou (male, 39 years old) were also stabbed when they came forward to dissuade them. The suspect Yin Moumou was then controlled on the spot. 120 After arriving at the scene for treatment, Zeng Moumou and Zhang had no vital signs at the scene, and Wei Moumou died in the process of being sent to the hospital.
