Point name meaning:

LI-11 may be named after its location; it is found at the crook of the elbow in a depression that resembles a shallow pool. This point name could also be considered as a description of qì as it pours into the uniting () point, which is like water pouring into a pool. This pool is located at the crook of the elbow, so it is the pool at the bend. For similar reasons, and because it is located on a yáng channel, an alternate name for this point is Yáng Marsh (see Cubit Marsh, LU-5).

Additionally, 曲池 (qū chí) was a place name in ancient China. See acupoint names: origins, meanings, and translations.
