Name and classical tradition
Huiyang, 会阳, is the “meeting of Yang.” 会 (會) means to gather, to converge; 阳 (陽) is Yang. The point is beside the coccyx, and the convergence the name indicates is that of the Bladder channel with the Du Mai, both of a Yang nature. The Zhenjiu Jiayi Jing (Systematic Classic of Acupuncture and Moxibustion) confirms this by describing it as a place «督脈脈氣所發», where the Qi of the Du Mai emerges. It is, then, a point with a dual affiliation, and the name reflects a classical fact, not a late gloss.
The reference works give it the alternative name 利機, “favorable mechanism.” Very close by, on the midline, is GV1, Changqiang, the point where the Du Mai begins.
