상명 (Sangmyeong) could be a word that is meant to be written in Hanja.

From wiktionary:

常明 (“eternal-bright”)

常 (transcribed as 상):

• “honorable; righteous; upright; dignified”
• “eternal; everlasting”
• “constant; frequent”

明 (trans. 명):

• “bright”

There’s also 詳明 (“detailed and clear”).

Both 常明 (“eternal-bright”) and 詳明 (“detailed and clear”) are Hanja transcribed as 상명 (Sangmyeong). Maybe it’s multiple choice?

It’s also the name of an university in Occupied Korea: Sangmyung University.
