For 60 years after the war, the world entered the digital age, while North Korea, which was closed to the outside world, belonged to a different category. This mysterious country has always been "partially covered". There are many incomprehensible places in North Korea. Some people said "North Korea today is very similar to China in the 1960s and 1970s"; some said "the life of North Korean civilians is very pleasant"; and others said "North Korea has become a country like an impregnable fortress." However, there is no doubt that North Korea is still a country that has not solved the problem of food and clothing, and many people are starving; it still maintains a fanatical worship of its leaders.
