少气多则肉而善瘃。（瘃者，皴裂。）血气皆少则无毛，有则稀，枯悴，善
痿厥足痹。（痿厥，痿厥并病，后世所称类中风者是也。）
足少阳之上，气血盛则通髯美长，（通髯，髯与发通，俗名兜腮。）
血多气少则通髯美短，血少气多则少髯，血气皆少则无髯，感于寒湿则善痹骨痛爪枯也。

胫毛美短，外踝皮坚而浓。血少气多则胫毛少，外踝皮薄而软。血气皆少则无毛，外踝瘦无肉。

（多少言其多也。）血少气多则面多肉。血气和则美色。（心主血脉，其华在面，此虽系足太阳，而
曰血气和，则心气和可知矣。）
足太阳之下，血气盛则跟肉满，踵坚。气少血多则瘦，跟空。血气皆少则喜转筋，踵下痛。

手太阳之下，血气盛则掌肉充满，血气皆少则掌瘦以
寒。（上指诸经之行头面者，下指其行手足者。前篇左右上下部位，义即指此。）
审察其形气有余不足而调之。按其寸口人迎，切循其经络之凝涩，结而不通者，此于身皆为痛痹，甚
则不行，故凝涩。凝涩者致气以温之，血和乃止。其结络者，脉结血不和，
决之乃行。故气有余于上者，导而下之。气不足于上者，推而休之。（休疑。）其稽留不至者，因而迎之。
必明于经隧，乃能持之。寒与热争者，导而行之。其菀（即郁字。）陈血不结者，则
（因也。马氏云作侧，非。）而予（上声。）之。必先明知二十五人，则血
气之所在，左右上下，可知逆顺矣。（总束上文，末句叫醒大义。上三阳上下气血多少形状。）

When blood is abundant and qi is scanty, the eyebrows are unattractive, and the face has many wrinkles (Duo-shao here implies abundance, i.e., many wrinkles). When blood is scanty and qi is abundant, the facial muscles are plump. When blood and qi are harmonious, the complexion is beautiful (The Heart governs blood vessels, and its flourishing is manifested in the face; although this section discusses the Foot-Taiyang meridian, mentioning "blood and qi harmony" implies that Heart Qi is also harmonious).
The lower part of the Foot-Taiyang Bladder Meridian: When blood and qi are abundant, the heel flesh is full, and the Achilles tendon area is firm. When qi is scanty and blood is abundant, the heel is thin, and the heel area feels empty. When both blood and qi are scanty, the person is prone to muscle spasms and pain under the heel.
Those with beautiful eyebrows have abundant blood and qi in the Foot-Taiyang meridian. Those with unattractive eyebrows have scanty blood and qi. Those who are fat and lustrous have excess blood and qi. Those who are fat but not lustrous have excess qi and deficient blood. Those who are thin and not lustrous have deficiency of both blood and qi.

The lower part of the Hand-Taiyang Small Intestine Meridian: When blood and qi are abundant, the palm flesh is full; when both blood and qi are scanty, the palm is thin and cold. (The "upper" mentioned above refers to the parts of the meridians running to the head and face, and the "lower" refers to those running to the hands and feet. The left-right and up-down locations mentioned in the previous chapter refer to this principle.)
Examine the form and qi for excess or deficiency and regulate accordingly. Palpate the Cun-kou (Radial artery) and Ying-kou (Carotid artery) pulses, and trace the meridians to feel for stagnation, sluggishness, or knotting and blockage. These conditions manifest throughout the body as Painful Bi Syndrome (Tong-Bi); in severe cases, movement is impaired, hence the term stagnation/sluggishness. For stagnation/sluggishness, promote the arrival of qi to warm the area; symptoms cease once the blood is harmonized. For knotted collaterals, where pulse knots indicate blood disharmony, release the blood through pricking to restore flow. Therefore, for qi excess in the upper body, guide it downward. For qi deficiency in the upper body, push and tonify it (Note: "Xiu" is uncertain, interpreted here as tonifying/supporting based on context). For qi/blood stagnation failing to arrive, follow the path to welcome and draw it in. One must clearly understand the meridians and collaterals to master these techniques. For conflicts between cold and heat, guide and facilitate circulation. For stagnant, old blood that is not knotted, remove it according to the situation (Note: "Yu" is interpreted as giving/treating/removing based on context; Ma's commentary suggesting "side" is incorrect). One must first understand the twenty-five different constitutions to know the distribution of blood and qi, thereby discerning the normal and abnormal patterns of the left, right, upper, and lower regions. (This summarizes the preceding text; the final sentence highlights the main principle. The above discusses the abundance, scarcity, and morphology of blood and qi in the three Yang meridians.)
