（胸中两乳之间，即上焦之分也）属手厥阴心包经、任脉之会（《灵枢》曰∶膻中者，
心主之宫城也。又曰∶膻中者，为气之海，其俞上在于柱骨之上下，前在于人迎。气海有余者，气满胸中，
息面赤；气海不足，则气少不足以言。《素问》曰∶任脉者，起于中极之下，以上毛际，循腹里，上关元，至
咽喉。又曰∶膻中者，臣使之官，喜乐出焉。注∶心主为君，以敷宣教令，膻中主气，以分布阴阳，故官为臣
使也。气适志和，则喜乐由生矣）。兼属手少阳三焦经（《灵枢》曰∶营气合少阳上行，注膻中，散于三焦。
又曰∶手少阳之脉，布膻中，散络心包。其支者，从膻中，上出缺盆）。又属足厥阴肝经（《灵枢》曰∶厥阴
根于大敦，结于玉茎，络于膻中）。
（臆前心蔽骨下尖头软骨，即鸠尾穴之分也，一名尾翳，言 象鸠鸟之尾而蔽心也。
如人无蔽骨者，可在两岐骨下，增同身寸之一寸）属手少阴心经、任脉之会（《灵枢》曰∶五脏六腑，心为之
主，缺盆为之道。 骨有余，以候 。无 者心高， 小短举者心下； 长者心下坚， 弱小以薄
者心脆； 直下不举者心端正， 倚一方者，心偏倾也。又曰∶任脉之别，名曰尾翳，下鸠尾，散于腹。
又曰∶膏之原，出于鸠尾，肓之原，出于脖 ）。
(Located in the center of the chest, between the two breasts, this area belongs to the Upper Jiao (Upper Burner)). It is the intersection point of the Pericardium Meridian of Hand-Jueyin and the Ren Mai (Conception Vessel). (*Ling Shu* states: "Dan Zhong is the palace city of the Heart Master." It also states: "Dan Zhong is the Sea of Qi; its Shu points are located above and below the vertebral column at the back, and anteriorly at the Ying Tang point. When the Sea of Qi is in excess, Qi fills the chest, breathing becomes rapid, and the face turns red; when the Sea of Qi is deficient, there is insufficient Qi to speak.") (*Su Wen* states: "The Ren Mai originates below the Zhong Ji point, ascends through the pubic region, follows the interior of the abdomen, passes through the Guan Yuan point, and reaches the throat." It also states: "Dan Zhong is the Official of the Envoy, from which joy and pleasure arise." Annotation: The Heart Master acts as the Sovereign, disseminating edicts and instructions; Dan Zhong governs Qi, distributing Yin and Yang, hence it is called the Envoy. When Qi is balanced and emotions are harmonious, joy arises naturally.) It also pertains to the San Jiao Meridian of Hand-Shaoyang (*Ling Shu* states: "Ying Qi combines with the Shaoyang meridian and ascends, entering Dan Zhong, and dispersing into the San Jiao." It also states: "The Hand-Shaoyang meridian distributes around Dan Zhong and networks with the Pericardium. Its branch originates from Dan Zhong, ascends, and emerges at the Que Pen point.") Furthermore, it relates to the Liver Meridian of Foot-Jueyin (*Ling Shu* states: "The Jueyin meridian roots at Da Dun, knots at the Yu Jing, and networks at Dan Zhong.")
(Located at the tip of the xiphoid process cartilage below the heart shield on the anterior chest, this is the location of the Jiu Wei acupoint, also known as Wei Yi, named because its shape resembles the tail of a dove and shields the heart. If an individual lacks this xiphoid process, the point can be located one Cun (using the patient's own body measurement) below the bifurcation of the costal margin). It is the intersection point of the Heart Meridian of Hand-Shaoyin and the Ren Mai (Conception Vessel). (*Ling Shu* states: "Among the Zang and Fu organs, the Heart is the master, and the Que Pen point serves as the pathway. An overdeveloped xiphoid process indicates the state of the Heart. Absence of the xiphoid process suggests a high-positioned Heart; a short and elevated xiphoid process suggests a low-positioned Heart; a long xiphoid process suggests a low and firm Heart; a small, weak, and thin xiphoid process suggests a fragile Heart; a straight and non-elevated xiphoid process suggests a properly positioned Heart; a deviated xiphoid process suggests an inclined Heart position." It also states: "The Luo-connecting vessel of the Ren Mai is named Wei Yi; it descends from the Jiu Wei point and disperses into the abdomen." It also states: "The source of Gao (fatty tissue) originates from Jiu Wei; the source of Huang (membranous tissue) originates from Bo Yang.")
