- (龍) dragon
- 개천에서 용 났다. (gaecheon-eseo yong nassda) This is said especially when a great man emerged out of the most unlikely background. This literally means that a dragon has emerged out of a brook. That is, what appears so unlikely happened strikingly in reality. It also suggests that a long river can be an analogy, embodiment, or at least birthplace of a dragon.
