Warning: This report contains details of physical and sexual abuse and discussion of suicide.

Baobao's heart still races when she smells soil after morning rain.

It takes her back to military drills behind locked gates - a traumatic time during her six-month stay at the Lizheng Quality Education School where instructors sought to fix teens deemed problematic by their families.

The experiences shared by Baobao and others, who entered these institutions due to various behavioral issues, detail extreme physical abuse and psychological trauma. Reports indicate that students were beaten severely, confined without academic support, and faced sexual abuse from staff members.

The ongoing investigation conducted by BBC's Eye program has corroborated these troubling allegations through interviews with former students and documented evidence, revealing how these institutions operate under a guise of discipline.

Furthermore, the phenomenon of parental desperation regarding their children's behavior, coupled with societal pressure for academic success, leads to the proliferation of such facilities across China, despite regulations against corporal punishment.

In the wake of public outcry and police intervention following investigative findings, questions remain about how these schools can continue to operate and reinvent themselves, undermining educational laws and protecting vulnerable youth.
