Point name meaning:

The spleen manages the blood and disperses essence, thus nourishing the body. The lung distributes this nourishment in the form of the qì and fluids through the body. SP-20 is located just below LU-1; because of its location, it can influence both the lung and the spleen and contribute to the nourishment of the whole body. Rendering this point's name as Complete Nourishment or All-Round Flourishing expresses this meaning.

周营 (zhōu yíng), All-Round Provisioning, is an alternate name for this point. This name more directly relates the nourishing nature of the point because 营 is the character that represents the nourishing aspect of qi-blood (i.e., 营气 yíng qì), provisioning qì, which is the theoretical complement of 卫气 (wèi qì), defense qì.
