King Taejong, who was afraid of owls that often flew into the palace, tried to get rid of owls on several occasions.

"Protect the palace by wearing a mask of Bangsang with four eyes" (January 15, 1411)

"I had to move out of the east gate because owls cried at the main building of the palace, and now they cry again. It would be better to hold a rite for them." (January 26, 1411)

"Follow the ritual of expelling palace ghosts (驅儺)" (January 26, 1411)
