Nearly a million Tibetan children live in state-run residential schools on the Tibetan plateau. Chinese authorities subject these children to a highly politicized curriculum designed to strip them of their mother tongue, sever their ties to their religion and culture, and methodically replace their Tibetan identity with a Chinese one. Children as young as four have been separated from their parents and enrolled in boarding kindergartens under a recruitment strategy based largely on coercion.
You're trivialising a serious issue. If you had actually read the article you'd know that they're definitely not just like any other public school and they're not just "teaching them Chinese and about society". It's an obvious and disgusting attempt to eradicate Tibetan culture.
