Indeed, we hardly get any information from North Korea,
But please don’t believe North Korean people still live in the same way as 30 years ago.
North Korea is still is one of the most undeveloped countries and has some super unbelievable laws. BUT it isnt different as you think.
some wrong information has been posted in other answers. I will not correct them. Just see the pictures.
some truth,
rural areas = Poverty.
Each email has been checked by the government if email to foreigners.
Lack of fuel (US's blockade) In the rural areas, you can see trucks use wood as energy.
Even the best geologists in the best colleges of North Korea hardly do the fieldwork, as it is quite difficult to get permission to buy gasoline.
