On March 28, the South Campus of Suining Senior High School in Jiangsu Province organized a 10-kilometer hiking activity for students without notifying their parents. During the hike, a student named Zhang Botao collapsed from exhaustion and died alone under a tree. According to parents, no school medical staff accompanied the event, and the supervisors failed to notice Zhang Botao had collapsed and passed away even after completing the entire route. On April 3, when parents went to the school to demand an explanation, they were reportedly assaulted by police, while school officials and teachers refused to appear or provide a response.
