About Korea and their cultural revolution...
The de-sinicization movement in Korea started in 1948, and by the 1970s, under the active policies of military dictator Park Chung-hee, Chinese language was purged completely from the Korean education system. Cold War and US influence played a huge part.
Koreans used the Chinese language up until the early 20th century, especially by scholars and the government, even though Hangul was already invented. If you go to Korea, any building or written document over 100 years old is likely to have Chinese characters on it.
Purging the Chinese language created a problem for them as most of their history was recorded in Chinese, so they are effectively history blind. Some older Koreans, those aged 50+ may know some Chinese characters but not good enough to read entire passages of text, only very few academics are fully read, while the young and middle aged of the populance are completely Chinese illiterate. Those with some knowledge of history dare not speak out and acknowledge the fact that Korean kingdoms spent centuries as Chinese imperial vassal states.
This created a situation now where rumors and unofficial history/urban legends have replaced real history - where Confucius was Korean, so was Daoism/Tai Chi, Kim Chi was invented in Korea instead of sprend to Korea from China; heck the way they tell the narrative - China and it's beings was a land of savage cannibals before being blessed with glorious Korean civilization!
Anyway, here we have some older Koreans writing Chinese calligraphy...
