It's a little known fact, but while non-Aryans weren't allowed to join the Nazi Party, they were allowed to fight in the Wehrmacht and certain divisions in the military arm of the SS. The Wehrmacht even had Mischlinge. Very fascinating.
Wait what felt like visiting China? Oh, speaking of China: in Chinese class we were talking about why our favourite colours were our favourites. Mine's red, so I raised my hand and said "red", along with a couple others. The teacher asked why we liked red and I raised my hand. She knew why :v
Visiting the Soviet Union feels like visiting China? Not quite. Things have changed in the past decades.
Actually, a component in the Chinese character for "red" means "worker". The Communist Party is commonly stated to be the "worker's party". This is why the colour red is associated most with communism, at least in China. (I guessed that by myself in class, heh. BRAAAAAIN SUUUUURGE)
