Hi. This is his video taking the regular train between NK and China. He made a playlist with his videos in NK.

I don’t know if there’s a way to generate translations from Portuguese to English, though.
Also, I don’t know what are China’s rules on immigration. They already have 500 trillion people, so they probably don’t make it easy to immigrate.
But no one in China will stop you from going from China to other countries. There are North Koreans that moved here to Brazil. And you can probably find them in other countries as well.
I would guess that the biggest barrier preventing anyone from migrating is that it’s hard as hell. Not the process itself, but leaving everything behind and moving far away, speaking another language.
And they would have to leave behind a country where they have free housing, absolutely zero taxes, good education, safety, and most important: guaranteed employment. So even though the US-imposed blockade makes their lives much harder, many people consider it to be better than moving to China and working 6 days a week in a low income job. Or working a low income job in any other nearby country.
