After the Korean War broke out, Chinese people's Volunteer Army entered Korea to resist US aggression and aid Korea. After more than three years of fierce fighting, the United States was finally forced to sign an armistice agreement on July 27, 1953. Keep the dividing line in the "38th parallel".
Later, South Korea became today's South Korea and North Korea became today's North Korea.
You can go to North Korea by train. There is an international train from China to North Korea in Dandong, Liaoning.
The fare is over 200.
Depart after ten in the morning and arrive at six in the afternoon. In fact, the real distance is only four hours' drive, but because it is transnational, the train needs customs inspection here in China before departure, and it will take much longer than four hours to arrive in North Korea and North Korea.
People there all speak Korean.
