（这是关于昼夜百刻与十二时辰定体图的解说）
手太阴肺经，配对手阳明大肠经，二者互为表里。以手为上部。手太阴肺经有五个穴位，属于阴穴；手阳明大肠经从阳经的大指次指内侧角起始，依次经过商阳、二间、三间、合谷、阳溪、曲池六个穴位。大肠属金，在地支中对应卯，在天干中对应庚。这就叫做阴阳表里、支干配合。
手厥阴心包络经，配对手少阳三焦经，二者互为表里。以手为中部。手厥阴心包络经有五个穴位，属于阴穴；手少阳三焦经有六个穴位，属于阳穴，从小指末端去爪甲角处起始，依次经过关冲、液门、中渚、阳池、支沟、天井。三焦属火，在地支中对应寅，在天干中对应甲。这就叫做阴阳表里、支干配合。

足厥阴肝经，配足少阳胆经，二者互为表里。足厥阴肝经上行至内踝上八寸处，交叉出足太阴脾经之后，这叫做“交经”。足厥阴肝经有五个穴位，属于阴穴，从足大指端大敦穴起始，依次经过行间、太冲、中封、曲泉。肝属木，在地支中对应亥，在天干中对应乙。足少阳胆经有六个穴位，属于阳穴，从足次趾端起始，依次经过窍阴、侠溪、临泣、丘墟、阳辅、阳陵泉。胆属木，在地支中对应申，在天干中对应甲。这就叫做阴阳表里、支干配合。
足太阴脾经，配足阳明胃经，二者互为表里。足太阴脾经在足厥阴肝经之前交叉进入。足太阴脾经有五个穴位，属于阴穴，从足大指内侧端起始，依次经过隐白、大都、太白、商丘、阴陵泉。脾属土，在地支中对应丑，在天干中对应己。足阳明胃经有六个穴位，属于阳穴，从足大指次趾端起始，依次经过厉兑、内庭、陷谷、冲阳、解溪、三里。胃属土，在地支中对应酉，在天干中对应戊。这就叫做阴阳表里、支干相配合。
足少阴肾经，配足太阳膀胱经，二者互为表里。足少阴肾经有五个穴位，属于阴穴，从足心凹陷处起始，依次经过涌泉、然谷、太溪、复溜、阴谷。肾属水，在地支中对应子，在天干中对应癸。足太阳膀胱经有六个穴位，属于阳穴，从小趾外侧起始，依次经过至阴、通谷、束骨、京骨、昆仑、委中。膀胱属水，在地支中对应戌，在天干中对应壬。这就叫做阴阳表里、支干相配合。
以上手足三阴三阳共十二条经脉，六十六个穴位，包括井穴、荥穴、输穴、经穴、合穴（此处原文作“井荣 经合”，实指五腧穴），配合金、木、水、火、土五行。经络气血流注，或交叉或直行，涉及表里内外关系及支干配合。各家针经图说对此进行了分析和讲解，因此我据此陈述其大概情况，并向先生请教，验证自己力所不及之处。对于道理上不同意的地方，再次接受教诲和指点，于是豁然开朗，如冰消融，如水流决口。心中有了学问，幸而不至于自相矛盾。凡是针刺孔穴，各有其依据的经络，需究明所关联的疾病证候、日辰禁忌以及虚实证候的补泻手法，这些不可不仔细考察。若能深明经络的分野和孔穴的位置，像这样操作，一百次中不会有几次失误。

These are the twelve meridians of the three Yin and three Yang of the hands and feet, comprising sixty-six acupoints, including the Jing-River-Well-Source-He-Sea points (Five Shu Points), paired with the Five Elements: Metal, Wood, Water, Fire, and Earth. The flow and distribution of meridians involve either crossing or direct paths, relating to exterior-interior and internal-external relationships, as well as the pairing of Earthly Branches and Heavenly Stems. Various schools of acupuncture classics and diagrams have analyzed and explained these concepts. Therefore, I have summarized the general principles here and consulted them with my teacher, verifying what was beyond my capability. For aspects where my understanding differed, I received further instruction and guidance, resulting in a sudden clarity, like ice melting or water bursting forth. With knowledge now in my heart, I am fortunate not to be self-contradictory. Whenever needling acupoints, one must rely on specific meridians, investigate the associated diseases and syndromes, observe daily and hourly taboos, and determine tonification and sedation based on deficiency and excess conditions. These matters must be carefully examined. If one thoroughly understands the differentiation of meridians and the locations of acupoints, such practice will rarely fail (one out of a hundred times).
