Lesson plans had to meet the approval of North Korean staff, every class was recorded and reported on, every room was bugged, and every conversation, overheard.
Учебните планове трябва да бъдат одобрени от севернокорейския екип, всеки урок бе записван и докладван, всяка стая бе наблюдавана и всеки разговор - подслушван.
