Can not find old newspapers, foreign newspapers.
You cannot find a newspaper that was printed a few years ago, even in a library. Foreign newspapers and magazines are of course banned from circulation. People and tourists can view newspapers daily because they are often posted on street signs or subway stations without buying..
No international calls.
Mobile phones are not too rare in North Korea as before. However, locals are not allowed to make calls to foreign countries or even to foreigners in this country. All SIM cards only allow domestic calls.
No heater, heating system
There is no heater system in Korean families, if they want to take a warm bath they often go to public baths. They also do not have a heating system, so to warm the house, people still use wood-burning furnaces, even in Pyongyang, as the country has many problems with power supply.
Do not sell Coca Cola
Before 2015, only two countries around the world banned Coca Cola from Cuba and Korea. When this drink is finally allowed to be sold in Cuba, North Korea is the only country that does not sell this globally famous drink.
Only routes to Russia and China.
Korean citizens cannot buy international air tickets to fly to another country for vacation. Not because it is expensive but because this action is prohibited. Even domestic travel is controlled, if people want to visit relatives in other villages, they must receive permission before departure. However, there are a few people who can go abroad to earn money, but the destination is only Russia and China.
