Were you wondering what was up with Uee’s hand rubbing as she begged Kim Yong Geon to reconsider in Episode 7 of Marriage Contract? 저도요 (me, too). I researched and here’s what I found.
Rubbing hands up and down with palms pressed together in prayer position is characteristic of 비손, pronounced bee-sohn (not to be confused with the shaggy North American animal in the photo, which is pronounced by-sun). Bison is a Korean folk rite used to pray for a wish to come true, or for a cure for a disease.
It looks as though it may be a woman’s ritual, though that is not clear – check out this explanation from the Encyclopedia of Korean Folk Beliefs (click to enlarge):
As the article explains, the 비 in 비손 is the verb stem of 빌다 (to pray, beg, or imprecate), and 손 is the word for hand.
