Mu-Bi (Korean: 무비; Hanja: 無比) was the concubine of King Uijong of Goryeo[1][2] who was expelled from the palace during the Munsin Coup.
Official Mun Geuk-gyeom (문극겸) also appealed to Baek's death and said that they were wasting wealth by seducing the King with the spirit and superstition of the magician by engaging in obscene behavior.
[7][8] According to Annals of the King Uijong of Goryeo, pointed to Buddhism and ghost worship, flattering servants, deceitful eunuchs and magicians, and monarchs as the causes of his fall.
[4] Although Choe's wife was the daughter of a King, her mother was of low birth, so her husband should also be restricted from public office.
Mu-Bi's sons were not treated like royal princes and just called as "Little Master" (소군; 小君), also forced to be into middle class.
