I suddenly remembered all those Norko tourists I seen in Vladivostok. These were very shy ones https://ibb.co/6BvNdFw . There used to be years when the city was squirming with them, then they suddenly all disappeared almost overnight.

Funny moments I remember. Two Korean tourists stood in line for an icecream stall, started chitchat. Then one in better dress turns to another, suddenly suspicious, sees Kim's pin on another guy's tshirt, and then he freezes, turning pale, and speechless.
