在英国，没有一个老师敢随随便便带自闭症儿童出远门

An eight-year-old boy, reportedly on the autism spectrum, went missing on a summer camp climb in Yunnan; by the second day more than three hundred people, two search dogs, four drones and five thermal imagers were looking for him. Dr Zhihao Yan's first reaction was that after months in an English state school's autism provision he would not have accepted that job. He describes what the provision actually looks like: classes of no more than eight, a specialist teacher and four assistants, door handles mounted out of reach, safety scissors, craft materials chosen to be edible. Even there a boy under one-to-one supervision swallowed something and was taken to hospital. Residential trips in England normally start around Year 5, and for autistic children often not at all. He is blunt about the camp organisers' belief that autism is caused by absent fathers and cured by more male staff.
