Many cultures under, or in the shadow of, an empire sometimes make use of that empire’s language to express themselves. Latin was used throughout Europe, while for a couple of centuries after the Norman conquest, the dominant written language in England was French. China exerted a similar cultural pull over its neighbors: Japanese poets would write kanshi and Koreans hansi, both terms being probably derived from the word Han, referring to the Han Dynasty (206 BCE-220 CE) in China. For both, using written Chinese was to make a cultural statement, indicating that these writings were for an elite class of people. Furthermore, despite the invention of hangul, an optimized Korean script, by king Sejong in the 15th century, classical Chinese—both the language and the script—remained the preference of Korean literati for several centuries. Hangul did not in fact hit its stride until well into the 19th century; and, given their acute sense of class-consciousness, Koreans may simply have felt more comfortable reading their stories in classical Chinese.
