望，闻，问，切，谓之四诊，兹采各书之要言不烦者，而列于下。
额心、鼻脾、左颊肝、右颊肺、颧肾，面上之部位可察也。肝青，肺白，心赤，脾黄，
肾黑，面上之五色可察也。部位察其相生相克，五色察其有神无神。大抵外感不妨滞浊，久

手部的三条阴经从内脏运行到手部，从手部运行到头部的则是手部的三条阳经。足部的三条阳经从头走向足部，足部的三条阴经（从足部）上行至腹部，这些要点需要仔细参详。（手太阴肺经、手少阴心经、手厥阴心包经都是从内脏走到手部。手阳明大肠经、手太阳小肠经、手少阳三焦经都是从手部走到头部。足太阳膀胱经、足少阳胆经、足阳明胃经都是从头部向下走到足部。足太阴脾经、足少阴肾经、足厥阴肝经都是从足部向上走入腹部。在十二经脉之外还有督脉，起自屏翳穴，止于唇内上龈交穴。任脉起自会阴穴，止于下龈交穴。加上上面的十二经脉，共有十四条经脉。）
肺经的络穴是列缺，大肠经的络穴属于偏历。胃经有丰隆作为络穴，脾经则以公孙为详述之络穴。心经的络穴通里，小肠经的络穴属支正。膀胱经的络穴是飞扬，肾经的络穴是大钟彰显。心包经的内关穴，三焦经的外关穴是其藏络之处。胆经的络穴是光明穴，肝经的络穴蠡沟不可忘记。任脉起于屏翳（会阴），督脉络于长强。更有脾之大络名为大包，胃之大络虚里位于左侧旁。（各条经脉的络穴只有一个，而脾胃两条经脉各有两个络穴，为什么呢？这是因为脏腑以脾胃为本源，十二条经脉都依赖脾胃之气来滋养。）
寅时对应肺经，卯时对应大肠经，辰时对应胃经，巳时对应脾经，午时对应心经，未时对应小肠经，申时对应膀胱经，酉时对应肾经，戌时对应心包经，亥时对应三焦经，子时对应胆经，丑时对应肝经。
记住多血多气的经脉，手部是大肠经，足部是胃经；少血多气的有六条经脉，分别是三焦经、胆经、肾经、心经、脾经、肺经；多血少气分为四条经脉，分别是膀胱经、小肠经、肝经和心包经。
望、闻、问、切，称为四诊，这里选取各书中简明扼要的内容，列举如下。
额头对应心脏，鼻子对应脾脏，左颊对应肝脏，右颊对应肺脏，颧骨对应肾脏，面部的部位可以据此观察。青色对应肝脏，白色对应肺脏，赤色对应心脏，黄色对应脾脏，黑色对应肾脏，面部的五色可以据此观察。通过部位观察其相生相克的关系，通过五色观察其有神还是无神。大抵外感病不妨碍面色略显滞浊，久病则忌讳呈现鲜妍之色，只有黄色出现在面目之间，既不枯槁也不浮泽，这是将要痊愈的征候。
The three Yin meridians of the hand travel from the zang organs to the hand, and the three Yang meridians of the hand travel from the hand to the head. The three Yang meridians of the foot travel from the head to the foot, and the three Yin meridians of the foot (from the foot) ascend to the abdomen; these key points must be carefully studied. (The Lung Meridian of Hand-Taiyin, Heart Meridian of Hand-Shaoyin, and Pericardium Meridian of Hand-Jueyin all travel from the zang organs to the hand. The Large Intestine Meridian of Hand-Yangming, Small Intestine Meridian of Hand-Taiyang, and Sanjiao Meridian of Hand-Shaoyang all travel from the hand to the head. The Bladder Meridian of Foot-Taiyang, Gallbladder Meridian of Foot-Shaoyang, and Stomach Meridian of Foot-Yangming all travel downward from the head to the foot. The Spleen Meridian of Foot-Taiyin, Kidney Meridian of Foot-Shaoyin, and Liver Meridian of Foot-Jueyin all travel upward from the foot into the abdomen. Beyond the twelve regular meridians, there is the Du Mai (Governing Vessel), which originates at the Pingyi point [Huiyin] and ends at the Shangyingjiao point inside the upper lip. The Ren Mai (Conception Vessel) originates at the Huiyin point and ends at the Xiayingjiao point. Combined with the aforementioned twelve meridians, there are fourteen meridians in total.)
The Luo-connecting point of the Lung Meridian is Lieque (LU7); the Luo-connecting point of the Large Intestine Meridian is Pianli (LI6). The Stomach Meridian has Fenglong (ST40) as its Luo point; the Spleen Meridian details Gongsun (SP4) as its Luo point. The Luo-connecting point of the Heart Meridian is Tongli (HT5); the Luo-connecting point of the Small Intestine Meridian is Zhizheng (SI7). The Luo-connecting point of the Bladder Meridian is Feiyang (BL58); the Luo-connecting point of the Kidney Meridian is Dazhong (KI4). The Neiguan (PC6) point belongs to the Pericardium Meridian of Hand-Jueyin; the Waiguan (TE5) point houses the Sanjiao Meridian of Hand-Shaoyang. The Luo-connecting point of the Gallbladder Meridian is Guangming (GB37); do not forget the Ligou (LR5) point of the Liver Meridian. The Ren Mai originates at Pingyi (Huiyin, CV1); the Du Mai connects at Changqiang (GV1). Furthermore, the Great Luo of the Spleen is named Dabao (SP21); the Great Luo of the Stomach, Xuli (ST15), is located on the left side. (Each of the regular meridians has only one Luo-connecting point, whereas the Spleen and Stomach meridians each have two. Why? Because the zang-fu organs consider the Spleen and Stomach as their root, and the twelve meridians all receive qi from them.)
At Yin hour, the Lung Meridian is active; at Mao hour, the Large Intestine Meridian; at Chen hour, the Stomach Meridian; at Si hour, the Spleen Meridian; at Wu hour, the Heart Meridian; at Wei hour, the Small Intestine Meridian; at Shen hour, the Bladder Meridian; at You hour, the Kidney Meridian; at Xu hour, the Pericardium Meridian; at Hai hour, the Sanjiao Meridian; at Zi hour, the Gallbladder Meridian; at Chou hour, the Liver Meridian.
Remember the meridians with abundant blood and qi: the hand meridian is the Large Intestine, and the foot meridian is the Stomach. There are six meridians with scanty blood but abundant qi: Sanjiao, Gallbladder, Kidney, Heart, Spleen, and Lung. There are four meridians with abundant blood but scanty qi: Bladder, Small Intestine, Liver, and Pericardium.
Inspection (Wang), Auscultation and Olfaction (Wen), Inquiry (Wen), and Palpation (Qie) are called the Four Diagnostic Methods. Here, we select the concise and essential statements from various books and list them below.
The forehead corresponds to the Heart, the nose to the Spleen, the left cheek to the Liver, the right cheek to the Lung, and the cheekbones to the Kidney; thus, the facial regions can be observed. Green corresponds to the Liver, White to the Lung, Red to the Heart, Yellow to the Spleen, and Black to the Kidney; thus, the five colors of the face can be observed. One observes the generation and restriction relationships through the regions, and the presence or absence of spirit through the five colors. Generally, external contraction disorders may allow for a slightly turbid complexion, while chronic diseases should avoid presenting a fresh and lustrous color. Only when yellow appears on the face and eyes, neither withered nor floating/greasy, is it a sign of impending recovery.
