Point name meaning:

The word passage (关 guāng) in the point name reflects the function of the triple burner as a conduit for the passage of qì from the upper to the lower body. Here, the character (chōng) may be considered as a reference to PC-1 as a point where the qì changes channels i.e., a hub.

This point is located on the tip of the ring finger. The names of the points on the tips of the middle and small fingers include the character (冲). The ring finger lies in between the other hubs, PC-9 and HT-9, resembling a passageway between them. The character (chōng) also may refer to the surging flow of qì at this point.

The qì at the well (jǐng) points is usually described as small and still, like the water of a well. It is perhaps the nature of the reaction that these points evoke when they are needled that results in them also being described as places of surging qì. PC-9 and HT-9 are other well (jǐng) points that have the character (chōng), to surge, in their point names. See acupoint names: origins, meanings, and translations.
