〔大指〕属手太阴肺经（《灵枢》曰∶手太阴之脉，循鱼际，出大指之端。又曰∶手太阴
之筋，起于大指之上。又曰∶肺出于少商。少商在手大指端内侧，为井木）。〔大指次指〕属手阳明大肠经（即
第二指也，一名食指，又名盐指。《灵枢》曰∶手阳明之脉，起于大指次指
之端。所生病者，大指次指痛不用。又曰∶手阳明之筋，起于大指次指之端，结于腕上。又曰∶大肠出于商
阳，商阳在大指次指之端，为井金）。〔中指〕属手厥阴心包经（一名将指。《灵枢》曰∶手厥阴之脉，循中
指出其端。其支者，别掌中，循小指次指出其端。又曰∶手心主之筋，起于中指。又曰∶心出于中冲。中冲，
在手中指之端，为井木。顾英白曰∶心包，亦名心主，而心脉即出于中冲，则手厥阴之与手少阴，同为心脉
无疑也。厥阴脉之支者，循小指次指出其端，则手少阳之亦为心脉，可知矣。故中冲、关冲、少冲，三指之井
穴皆以冲名，象火之有三焰也。读者幸无胶柱而鼓瑟焉）。〔小指次指〕属手少阳三焦经（即第四指也，今
称无名指。《灵枢》曰∶手少阳之脉，起于小指次指之端。所生病者，小指次指不用。又曰∶手少阳，出于
关冲，在手小指次指之端）。〔小指内廉〕属手少阴心经（小指，又名禁指。《灵枢》曰∶手少阴之脉，循小
指之内出其端。又曰∶手少阴之筋，起于小指之内侧）。〔小指外廉〕属手太阳小肠经（《灵枢》曰∶手太阳
之脉，起于小指之端。又曰∶手太阳之筋，起于小指之上。又曰∶小肠，出于少泽。少泽，小指之端也。沈承
之曰∶小指赤白肉际，属手太阳小肠经）。
【大拇指】归属于手太阴肺经（《灵枢》记载：手太阴肺经的经脉，沿着鱼际部位行走，终止于大拇指的末端。又说：手太阴肺经的筋脉，起始于大拇指的上部。又说：肺经的原气出于少商穴。少商穴位于大拇指内侧末端，五行属木，为井穴）。【大拇指旁边的食指】归属于手阳明大肠经（即第二指，又名食指，又被称为盐指。《灵枢》记载：手阳明大肠经的经脉，起始于大拇指旁边食指的末端。该经所导致的病症包括：大拇指和食指疼痛且功能丧失。又说：手阳明大肠经的筋脉，起始于大拇指旁边食指的末端，汇聚于手腕上方。又说：大肠经的原气出于商阳穴，商阳穴位于大拇指旁边食指的末端，五行属金，为井穴）。【中指】归属于手厥阴心包经（又名将指。《灵枢》记载：手厥阴心包经的经脉，沿着中指行走并到达其末端。其分支从手掌中分出，沿着小指旁边的无名指行走并到达其末端。又说：手厥阴心包经的筋脉，起始于中指。又说：心包经的原气出于中冲穴。中冲穴位于手中指的末端，五行属木，为井穴。顾英白说：心包，也称为心主，而心脉即从中冲穴发出，那么手厥阴经与手少阴经，同为心脉无疑。手厥阴经的分支，沿着小指旁边的无名指行走并到达其末端，那么手少阳经也属于心脉，可以推知了。因此，中冲、关冲、少冲这三个手指的井穴都以“冲”命名，象征着火焰有三股焰苗。读者希望不要拘泥固执地弹琴）。【小指旁边的无名指】归属于手少阳三焦经（即第四指，现在称为无名指。《灵枢》记载：手少阳三焦经的经脉，起始于小指旁边无名指的末端。该经所导致的病症包括：小指旁边的无名指功能丧失。又说：手少阳三焦经，原气出于关冲穴，位于小指旁边无名指的末端）。【小指内侧】归属于手少阴心经（小指，又名禁指。《灵枢》记载：手少阴心经的经脉，沿着小指的内侧行走并到达其末端。又说：手少阴心经的筋脉，起始于小指的内侧）。【小指外侧】归属于手太阳小肠经（《灵枢》记载：手太阳小肠经的经脉，起始于小指的末端。又说：手太阳小肠经的筋脉，起始于小指的上方。又说：小肠经的原气出于少泽穴。少泽穴位于小指的末端。沈承之说：小指赤白肉际处，归属于手太阳小肠经）。
[The thumb] belongs to the Hand-Taiyin Lung Meridian (Ling Shu states: The meridian of Hand-Taiyin follows the thenar eminence and emerges at the tip of the thumb. It also states: The sinew of Hand-Taiyin originates from the upper part of the thumb. Furthermore: The Lung meridian issues from Shaoshang (LU-11). Shaoshang is located on the radial side of the tip of the thumb, belonging to Wood as the Jing-Well point). [The index finger, adjacent to the thumb] belongs to the Hand-Yangming Large Intestine Meridian (i.e., the second finger, also known as the食指 Index Finger or 盐指 Salt Finger. Ling Shu states: The meridian of Hand-Yangming originates from the tip of the index finger. Diseases generated by this meridian include pain and dysfunction of the thumb and index finger. It also states: The sinew of Hand-Yangming originates from the tip of the index finger and knots above the wrist. Furthermore: The Large Intestine meridian issues from Shangyang (LI-1), which is located at the tip of the index finger, belonging to Metal as the Jing-Well point). [The middle finger] belongs to the Hand-Jueyin Pericardium Meridian (also known as the Jiangzhi General Finger. Ling Shu states: The meridian of Hand-Jueyin follows the middle finger and emerges at its tip. Its branch separates from the palm, follows the ring finger, and emerges at its tip. It also states: The sinew of the Hand-Jueyin Pericardium originates from the middle finger. Furthermore: The Heart meridian issues from Zhongchong (PC-9). Zhongchong is located at the tip of the middle finger, belonging to Wood as the Jing-Well point. Gu Yingbai stated: The Pericardium is also called the Heart Master, and since the Heart meridian issues from Zhongchong, it is undoubtedly that both the Hand-Jueyin and Hand-Shaoyin meridians are related to the Heart meridian. Since the branch of the Jueyin meridian follows the ring finger and emerges at its tip, it can be inferred that the Hand-Sanyang Sanjiao meridian is also related to the Heart meridian. Therefore, the Jing-Well points of these three fingers—Zhongchong, Guanchong, and Shaochong—are all named "Chong," symbolizing that fire has three flames. Readers should not play the lute with rigid tuning pegs, i.e., do not be dogmatic). [The ring finger, adjacent to the little finger] belongs to the Hand-Sanyang Sanjiao Meridian (i.e., the fourth finger, now commonly called the Ring Finger. Ling Shu states: The meridian of Hand-Sanyang originates from the tip of the ring finger. Diseases generated by this meridian include dysfunction of the ring finger. It also states: The Hand-Sanyang Sanjiao meridian issues from Guanchong (SJ-1), located at the tip of the ring finger). [The medial side of the little finger] belongs to the Hand-Shaoyin Heart Meridian (The little finger is also known as the Jinzhi Forbidden Finger. Ling Shu states: The meridian of Hand-Shaoyin follows the medial side of the little finger and emerges at its tip. It also states: The sinew of Hand-Shaoyin originates from the medial side of the little finger). [The lateral side of the little finger] belongs to the Hand-Taiyang Small Intestine Meridian (Ling Shu states: The meridian of Hand-Taiyang originates from the tip of the little finger. It also states: The sinew of Hand-Taiyang originates from the top of the little finger. Furthermore: The Small Intestine meridian issues from Shaoze (SI-1). Shaoze is located at the tip of the little finger. Shen Chengzhi stated: The junction of red and white skin on the little finger belongs to the Hand-Taiyang Small Intestine Meridian).
