This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.
A face region entry records a specific, named zone or feature the Chinese physiognomic tradition reads for meaning, a palace governing a particular life area, a facial feature assigned to a particular official role, considered for its documented position on the face and what the tradition's own texts say it indicates. A Textbook of Physiognomy, translating the classical Shenxiang quanbian manual, sets out these named regions and features as a documented, systematic reading method taught and transmitted across a real textual tradition rather than an informal folk custom.
An entry records a region's documented facial position, the life area or quality the tradition assigns it, and which classical text first attests or most fully describes that assignment, since different manuals within the tradition sometimes name and divide the face's regions somewhat differently.
Where a region's assigned meaning has shifted across different periods of the tradition's own long documented history, an entry records that development honestly, treating the tradition's own textual history as part of what the region means rather than presenting one fixed reading as timeless.
An entry also records which specific classical manual first attests a given region's name and boundary, since the tradition's named regions were not all introduced at the same point in its long documented history, and treating them as a single unchanging set obscures a genuinely layered textual development.
