One of the children, a six-year-old Chinese national, was abused for 18 hours and forced to drink his own urine.
On Thursday, the 31-year-old pleaded guilty to two counts of child abuse, one count of voluntarily causing grievous hurt and one of giving false or misleading information to police, local media reported.
The man, who cannot be named to protect the children’s identity, was hired by his aunt in 2016 to manage her educational facility, which provided accommodation and management consultancy services for students and workers.
Despite having no childcare or teaching qualifications, he was responsible for the pupils at the facility, teaching them mathematics and English and checking their homework.
In January 2023, the six-year-old entered the facility, where the man regularly punished him, forced him to sleep in the toilet and fed him only bread and water.
