After Tan came to study in the study room, Hu pointed multiple axes at Tan's head and neck from behind, then dragged Tan to the ground and continued to cut several axes on his head, causing the victim to die on the spot. Then Hu called 1 10 to call the police, but failed to get through, and was subdued by the school security guard who heard the news. Hu confessed to his criminal facts.
