从统一校服到独自跨国飞行：我在希思罗看到两种“出国”方式

Waiting at Heathrow for children arriving for a summer camp, Dr Zhihao Yan watches two versions of going abroad come through the same doors. Chinese groups emerge dozens at a time in matching tracksuits, with a group leader, shared classes, shared meals and a shared write-up on return — a low-risk collective outing that is barely an international experience at all. Then French, German and Spanish thirteen-year-olds walk out alone with battered backpacks, find the camp staff, sit down on their bags and eat a sandwich they packed themselves. He argues the gap is not ability but practice: those children started years earlier. He sets out what his own camp does about it — a pre-departure cultural briefing covering gender norms and they/them pronouns, a rule that speaking badly beats staying silent, a cap of 15% Chinese speakers per class, and phones held centrally. And what parents have to do: disappear.
