The Difference Between Modern Standard Chinese and Classical Chinese (Why Learn Classical Chinese)

The representative characteristics of Classical Chinese are conciseness and metaphor.
You can see this just by looking at four-character idioms (Chengyu).
Since people in the Sinosphere learn Classical Chinese in school, just like in Korea,
they frequently use metaphorical expressions from Classical Chinese in daily life.
Furthermore, because 70% of Korean and Japanese vocabulary is constructed based on Classical Chinese grammar,
Classical Chinese is also taught as a subject in schools.
North Korea once abolished Classical Chinese but reinstated it in the 1970s due to issues with vocabulary proficiency.
Even modern terms (such as culture, enlightenment, overseas, etc.) that are often said to have been created in Japan
were constructed using the grammatical principles and concise metaphors of Classical Chinese.
