The official language of Korea is "Korean ()". ?

Korean is a cohesive language, which has been marked with Chinese characters in history and integrated into its vocabulary. Chinese characters have long occupied the position of mainstream characters in Korea. 1446 10, the fourth monarch of the Korean dynasty, King Sejong, promulgated "Training the People's Righteousness", which marked the birth of Korean and ended the history that South Korea did not have its own characters and borrowed China Chinese characters to mark it.

It is generally believed that Koreans began to use a large number of Chinese characters in the 6th-9th century (the language could not be recorded before). Due to the long-term contact with China culture, Chinese characters have long been the only official language of Koreans. It was not until the beginning of the 20th century that Korean proverbs began to be widely used in the official folk of the Korean kingdom.

Because Chinese characters are a writing system created to mark Chinese, Korean, which is completely different from Chinese, should be marked. Therefore, since the 6th century, people have been trying to mark Korean with Chinese characters.
