《黄帝内经·灵枢·五阅五使》
岐伯说：五官的气色不分明，两眉之间和额头不开阔，鼻子窄小，脸颊至耳门的肌肉不饱满，耳边四周骨骼和肌肉坍陷，下颚平陷，耳垂和耳上角尖窄且向外翻，像这样的人，在平时就体质很弱，更何况再遇到疾病呢？
岐伯曰：五官不辨，阙庭不张，小其明堂，蕃蔽不见，又埤其墙，墙下无基，垂角去外，如是者，虽平常殆，况加疾哉？
Qi Bo said: Qi of five sense organs is not clear, the space between eyebrows and forehead is not wide enough, the nose is narrow, the muscle from cheek to ear gate is not full, the bone and muscle around the ears are sunken, the chin is sunken, earlobes and corners of ears are thin and turned outward, people like this have weak body in general, how can they overcome diseases?
