Name and classical tradition
Touwei, 头维, is the “corner of the head.” 头 is the head, and 维 (維) here has the sense of corner or vertex, the same as in the classical expression 四維, the four corners of the world. It can also be read as “to support” or “to delimit.” The point lies at the corner of the forehead, in the angle formed by the hairline, and the name places it at this boundary of the head.
Secondary sources refer it both to the Zhenjiu Jiayi Jing (Systematic Classic of Acupuncture and Moxibustion) and to the Lingshu (Spiritual Pivot), chapter Jing Mai, without a confirmed literal citation. It is a triple crossing point, where the foot Shaoyang and Yangming meet the Yang Wei Mai. The reference works give it an alternative name, 顙大, “large forehead,” which reinforces its location.
