Despite the fact that tablets are available in the country, paper notebooks remain the favoured medium. "These are pictures that will be broadcast on television and shown in the state media, so those who are there want to be seen recording Kim Jong-un's every word," says Grayson. "It's about presenting him as having broad knowledge - however, it's ridiculous, he can't possibly know about all of these different things. It's important, however, that the apparatchiks that surround him are seen to be hanging on his every word."
According to Prof Steve Tsang, chair the School of Contemporary Chinese Studies at the University of Nottingham, the note-takers will be writing extremely carefully. "They wouldn't want to write down anything that was, say, politically inaccurate, or it might come back to bite them." The notes are not usually published or available for the public to view, says Tsang. "If anything comes out of them, it would be via the propaganda department. Whether it was what was actually said, or is different to the guidance given at the time, doesn't matter. No-one will ever question it. If you were at the factory and the advice that was released wasn't quite what you had in your notebook - what are you going to do about it?"
