明堂图（面部脏腑分属图）。内部对应十四处，外部对应十一处，恐怕在匆忙之间难以辨别。唯有相传的额头属心、鼻部属脾、左颊属肝、右颊属肺、颏部属肾的方法，简便快捷且可遵循。又必须审视其五色，以确定五脏的疾病。（肝色青，肺色白，心色赤，脾色黄，肾色黑。）色泽遍布全面的，辨别其有神或无神；色泽分部显现的，审查其相生相克关系。色泽暗淡的，病从内生；色泽紫浊的，邪气自外受入。郁结多表现为憔悴，病程长久则消瘦发黄。山根（鼻根部）明亮，须知是欲愈之兆；口周发黑黧黑，切勿医治已绝之肾证。言语难尽意旨，医理需会心领悟。
经典记载：红色如帛裹朱砂，不要如赭石；白色如鹅羽，不要如盐；青色如苍璧之光泽，不要如蓝草；黄色如罗裹雄黄，不要如黄土；黑色如重漆之色，不要如地苍。青色如翠鸟羽毛者生，红色如鹅冠者生，黄色如蟹腹者生，白色如猪脂者生，黑色如乌鸦羽毛者生。《灵枢》说：五色各见于其所属部位，观察其浮沉，以知病位深浅；观察其润泽枯槁，以观病情成败；观察其散漫或聚结（音团），以知病程远近；视色泽上下分布，以知病处所在。积精神于心，以知晓既往规律。
尸臭。（肉绝。）舌卷缩及阴囊收缩。（肝绝。）口不合。（脾绝。）肌肉肿胀唇反张。（胃绝。）头发直竖牙齿枯槁。（骨绝。）遗尿。（肾绝。）毛发焦枯。（肺绝。）
面色黑而直视，闭目不见。（阴绝。）眼眶凹陷，目系倾斜，汗出如珠。（阳绝。）手撒开戴眼（眼球上翻）。（太阳经绝。）病后喘促泄泻。（脾肺将绝。）眼睛正圆固定不动。（不治。）吐沫面赤，面青黑，嘴唇青人中饱满，头发与眉毛冲起，爪甲下肉黑，手掌无纹，脐突，足背肿，声音如鼾睡。
脉象方面：足爪甲青或脱落，呼骂不休。（筋绝。八日死。）眉息回视。（心绝立死。）头发直如麻，不得屈伸，自汗不止。（小肠绝。六日死。）
口冷足肿，腹热胪胀，泄利无时。（肺绝。五日死。）脊骨疼肿，身重不可转侧。（胃绝。五日死。）耳干，舌肿，溺血，大便赤泄。（肉绝。九日死。）口张，气出不反。（肺绝。二日死。）泄利无度。（大肠绝。）齿干枯，面黑，目黄，腰欲折，自汗。（肾绝。）
Mingtang Tu (Facial Zang-Fu Mapping Chart). The internal areas correspond to fourteen, and the external areas to eleven; it is feared that one may not be able to distinguish them in a hurry. Only the traditionally transmitted method—forehead corresponds to Heart, nose to Spleen, left cheek to Liver, right cheek to Lung, and chin to Kidney—is simple, direct, and followable. One must also examine the five colors to determine diseases of the five Zang organs. (Liver is green, Lung is white, Heart is red, Spleen is yellow, Kidney is black.) When color spreads over the whole face, distinguish whether there is Shen Spirit or not; when color appears in specific zones, examine their mutual generation and restriction. Dull and dim colors indicate disease arising from within; purple and turbid colors indicate pathogenic factors acquired from outside. Stagnation often manifests as haggardness; prolonged illness leads to emaciation and sallow yellow complexion. Brightness at Shan Gen (root of the nose) indicates an impending recovery; darkening around the mouth suggests Kidney essence exhaustion, which should not be treated. Words cannot fully express the meaning; medical principles require intuitive understanding.
The Classics state: Red should resemble silk wrapping cinnabar, not ochre; white should resemble goose feathers, not salt; green should resemble the luster of dark jade, not indigo; yellow should resemble silk wrapping realgar, not loess soil; black should resemble double-lacquered color, not earthy gray. Green like kingfisher feathers indicates life; red like goose comb indicates life; yellow like crab belly indicates life; white like pig fat indicates life; black like crow feathers indicates life. *Ling Shu* says: Each of the five colors appears in its respective zone; observe its floating or sinking to know depth; observe its luster or withering to judge success or failure; observe its dispersion or aggregation (pronounced "tuan") to know duration; view the distribution of color up and down to locate the disease site. Accumulate spirit in the heart to understand past patterns.
