Ghost Town
Get this — in order to make a city look plentiful and alive, especially for foreign satellites and spy planes, the Hermit Kingdom’s government will occasionally have an entire population of a town to pack their things and relocate to a different city. By moving an entire town from one to another will seemingly make it look “populated” to outside observers.
The Power Of The Military
Farms, houses, office buildings… you name the place and the military will 100% be there. Whether it’s telling people when the train is coming and going, the government has put military everywhere to ensure their population is in line.
