This episode of the Korea Now podcast features an interview that Jed Lea-Henry conducted with Sixiang Wang. They speak about the exchanges between Choson Korea (1392-1910) and Ming China (1368-1644), the Korean envoys and interpreters who mediated between the two dynasties, the need of these interpreters to master spoken Chinese, the extensive body of language materials that were created for this purpose, and the invention of the Hangul script to systematically represent the phonology of Sino-Korean.
