《黄帝内经·灵枢·天年》
岐伯说：长寿的人，人中沟深而且长，面部的脸颊和下颌等部位的骨高肉厚而且端正，营气和卫气的运行调和通畅，头面上部的额头、中部的鼻梁、下部的下巴这面相的三庭都隆起没有坍陷，骨骼高大，肌肉丰满，有这些征象的人，就可以活到一百岁。
岐伯曰：使道隧以长，基墙高以方，通调营卫，三部三里起，骨高肉满，百岁乃得终。
Qi Bo said, "People who live long have a deep and long groove in the middle of their faces, and the bones on their cheeks and jaws are high, fleshy, and regular. The nourishment and protection qi circulate in a balanced and unobstructed manner. The three sections of physiognomy - the forehead, the bridge of the nose, and the chin - are all raised and not sunken. The bones are tall, the muscles are full, and people with these characteristics can live to be 100 years old.
