Translation:The northern countries of Asia are cold during the winter.
Northern countries of Asia? Is there any country in the northern part of Asia besides Russia?
Yay Korea! When I was young I thought it snowed everywhere every winter
Russia is a bit blown up in our world maps because it's near the poles. Just like how Greenland often looks about the same size of Africa on the Mercator maps we usually use, when in reality it doesn't even come close. (comparison image)
If you look at a map with actual proportions, like this one, then you see that Kazakhstan, Mongolia, Japan, Korea and the northern half of China are considerably farther north than it usually seems on world maps. Together they about the same size as the Asian regions of Russia.
