Sinmi

Sinmi (Korean: 신미; Hanja: 信眉), born Kim Su-seong (Korean: 김수성; Hanja: 金守省) from the Yeongdong Kim clan, was a Seon Buddhist monk in the early Joseon dynasty who was depicted in the 2019 film The King's Letters for his role in the creation of Hangul helping King Sejong.

In the Yeongdong Kim genealogy records, it was said that Sinmi was active as a scholar before his death, but there is no such record in the Annals of the Joseon Dynasty. Meanwhile in Sejong Sillok, it was recorded that his younger brother, Kim Su-on (김수온) helped Grand Prince Suyang and Grand Prince Anpyeong in translating some of the Buddhist scriptures.
