一切痰症，脉有虾游、雀啄、代止之形，须知其痰凝气滞，关格不通，脉因有不动者。有两三路乱动
者，有时无者，或尺寸一有一无者，有关上不见者，或时动而大小不常者，有
平居之人忽然而然者，有素禀痰病不时而然者，有僵仆暴中而然者，皆非死脉也，实因痰而然。
脉有对看法，有正看法，有反看法，有平看法，有仄看法，有彻底看法。如有浮即有沉，
有大即有弱，有滑即有涩，有数即有迟。合之于病，则浮为在表，沉为在里；大为有余，
弱为不足；滑为血盛，涩为气少；动为搏阳，弦为搏阴；数为在腑，迟为在脏，此对看法也。如浮、大、
滑、动、数脉，气之有余，名阳，当知其中有阴病阳胜之机。沉、弱、涩、弦、迟脉，气之不足，名阴，
当知其中有阴胜阳病之机。此正看法也，夫阴阳之在天地也，有余而往，不足随之；不足而往，
有余从之。知从知随，气可与期。故其始也为浮、为大、为滑、为动、为数，其始也反沉、反弱、反涩、
反弦、反迟，是阳消阴长之机，其病为进；其始也为沉、为弱、为涩、为弦、为迟，其继也微浮、微大、
微滑、微动、微数，是阳进阴退之机，其病为欲愈。此反看法也。浮为阳，如更兼大、动、滑、
数之阳，是为纯阳，必阳盛阴虚之病矣；沉为阴，更兼弱、涩、弦、迟之阴脉，是为重阴，必阴盛阳虚之
病矣。此为平看法。如浮而弱、浮而涩、浮而弦、浮而迟者，此阳中有阴，其人阳虚而阴气伏于阳脉中也；
将有亡阳之变，当以扶阳为急务矣；如沉而大、沉而滑、沉而数者，此阴中有阳，其人阴虚而阳邪下陷于
阴脉中也，将有阴虚之患，当以存阴为深虑矣。此为仄看法。如五阳脉体不变，而始为有力之强阳，终为无
力之微阳，知阳将绝矣。五阴脉虽喜变阳，如忽然暴见，是阴极似阳，知反照之不长，余烬之易灭也，是
为彻底看法。更
有真阴真阳之看法。所谓阳者，胃脘之阳也，脉有胃气，是知不死；所谓阴者，真脏之脉也，脉见真脏
者死。然邪气来也紧而疾，谷气来也徐而和，此又不得以迟数等定阴阳矣。盖十脉中，浮沉是脉体，
大弱是脉势，滑涩是脉气，动弦是脉形，迟数是脉息，总是病脉，而非平脉也。
先哲云∶浮而无力为阳虚，沉而无力为阴虚。此道其常耳。然阴虚者必反见阴脉，故阳愈虚脉愈沉。
如沉之极而复浮，是微阳欲脱之兆也，若服药而渐浮，仅得中脉为吉。若忽然而浮，浮而短涩是肺之真脏
见，浮而散大是心之真脏矣。阳脉反是阴虚，然阴愈虚则愈浮，如浮极而复沉，是真阴已绝之兆。若服补
剂而渐沉，得中脉者吉。忽然而沉，或沉之散涩，或绵绵欲绝者，不可复治矣。此阴阳反作之脉法。
一切痰证，脉象出现虾游、雀啄、代止等形态时，必须知道这是因为痰凝气滞，导致关格不通，脉象因此出现不规律跳动的情况。有的脉象在多个部位乱动，有的时而消失，或者寸部和尺部一有一无，或者关上部位看不见脉象，或者时而跳动且大小不恒定，有的是平时健康的人突然发生这种情况，有的是素有痰病的人不时发作，有的是突然僵仆或暴中邪气而导致的，这些都不是死脉，确实是因为痰邪引起的。
诊脉有对看法、正看法、反看法、平看法、仄看法、彻底看法。如有浮脉就有沉脉，有大脉就有弱脉，有滑脉就有涩脉，有数脉就有迟脉。结合病症来看，则浮脉主表证，沉脉主里证；大脉主有余（实证），弱脉主不足（虚证）；滑脉主血盛，涩脉主气少；动脉主搏动于阳分，弦脉主搏动于阴分；数脉主腑病，迟脉主脏病，这就是对看法。如浮、大、滑、动、数脉，是气的有余，名为阳，应当知道其中包含阴病阳胜的机理。沉、弱、涩、弦、迟脉，是气的不足，名为阴，应当知道其中包含阴胜阳病的机理。这就是正看法。阴阳存在于天地之间，有余而来，不足随之；不足而来，有余从之。知道随从和跟随的关系，就可以预测气的变化。所以起初表现为浮、大、滑、动、数，随后反而出现沉、弱、涩、弦、迟，这是阳消阴长的机理，病情为进展；起初表现为沉、弱、涩、弦、迟，随后微现浮、大、滑、动、数，这是阳进阴退的机理，病情为欲愈。这就是反看法。浮脉属阳，如果更兼见大、动、滑、数的阳脉，这是纯阳，必然是阳盛阴虚的病；沉脉属阴，如果更兼见弱、涩、弦、迟的阴脉，这是重阴，必然是阴盛阳虚的病。这就是平看法。如浮而弱、浮而涩、浮而弦、浮而迟者，这是阳中有阴，其人阳虚而阴气伏于阳脉中，将有亡阳的变化，应当以扶阳为紧急事务；如沉而大、沉而滑、沉而数者，这是阴中有阳，其人阴虚而阳邪下陷于阴脉中，将有阴虚的祸患，应当以存阴为深虑。这就是仄看法。如五阳脉体不变，开始是有力的强阳，最终是无力的微阳，知道阳气将绝了。五阴脉虽然喜欢变为阳脉，但如果忽然暴现，这是阴极似阳，知道反照的光芒不长，余烬容易熄灭，这就是彻底看法。更有真阴真阳的看法。所谓阳，是指胃脘之阳，脉有胃气，就知道不死；所谓阴，是指真脏之脉，脉见真脏者死。然而邪气来势紧而疾速，谷气来势徐缓而平和，这又不能用迟数等来确定阴阳了。大概十种脉象中，浮沉是脉体，大弱是脉势，滑涩是脉气，动弦是脉形，迟数是脉息，总是病脉，而不是平脉。先哲说：浮而无力为阳虚，沉而无力为阴虚。这是说常理。然而阴虚者必然反过来见到阴脉，所以阳越虚脉越沉。如沉到极点又复现浮脉，这是微阳欲脱的征兆，如果服药后逐渐变浮，仅得中脉为吉。如果忽然变浮，浮而短涩是肺的真脏脉现，浮而散大是心的真脏脉现。阳脉反之亦然，但阴越虚则脉越浮，如浮到极点又复现沉脉，是真阴已绝的征兆。如果服用补剂后逐渐变沉，得中脉者为吉。如果忽然变沉，或沉而散涩，或绵绵欲绝者，不可再治了。这是阴阳反作的脉法。
In all phlegm syndromes, when the pulse presents forms such as shrimp swimming (Xia You), sparrow pecking (Que Zhuo), or intermittent stopping (Dai Zhi), one must understand that this is due to phlegm coagulation and Qi stagnation, causing obstruction of Guan Ge (gateways and restrictions), resulting in irregular pulse movements. Some pulses move chaotically across multiple positions, some disappear intermittently, some are present at the Cun position but absent at the Chi position, or invisible at the Guan position, some beat intermittently with varying magnitude, some occur suddenly in previously healthy individuals, some occur intermittently in those with a chronic predisposition to phlegm diseases, and some result from sudden collapse or acute strike. None of these are death pulses; they are indeed caused by phlegm.
Pulse diagnosis involves opposite viewing (Dui Kan), correct viewing (Zheng Kan), reverse viewing (Fan Kan), balanced viewing (Ping Kan), oblique viewing (Ze Kan), and thorough viewing (Di Tao Kan). For instance, where there is a floating pulse (Fu Mai), there is also a deep pulse (Chen Mai); where there is a large pulse (Da Mai), there is also a weak pulse (Ruo Mai); where there is a slippery pulse (Hua Mai), there is also a choppy pulse (Se Mai); where there is a rapid pulse (Shu Mai), there is a slow pulse (Chi Mai). Correlating with disease: floating indicates exterior syndrome, deep indicates interior syndrome; large indicates excess, weak indicates deficiency; slippery indicates abundant blood, choppy indicates deficient Qi; moving indicates agitation in Yang, wiry indicates agitation in Yin; rapid indicates Fu organ disease, slow indicates Zang organ disease. This is opposite viewing. Pulses such as floating, large, slippery, moving, and rapid indicate excess Qi, named Yang; one should recognize the mechanism of Yin disease with Yang predominance within them. Pulses such as deep, weak, choppy, wiry, and slow indicate deficient Qi, named Yin; one should recognize the mechanism of Yin predominance with Yang disease within them. This is correct viewing. Yin and Yang exist in heaven and earth; where there is excess, deficiency follows; where there is deficiency, excess accompanies. Understanding following and accompanying allows prediction of Qi changes. Thus, if initially presenting as floating, large, slippery, moving, rapid, and subsequently reversing to deep, weak, choppy, wiry, slow, this is the mechanism of Yang declining and Yin growing, indicating disease progression. If initially presenting as deep, weak, choppy, wiry, slow, and subsequently showing slight floating, large, slippery, moving, rapid, this is the mechanism of Yang advancing and Yin retreating, indicating recovery. This is reverse viewing. Floating is Yang; if accompanied by large, moving, slippery, rapid Yang pulses, it is pure Yang, necessarily indicating Yang excess and Yin deficiency disease. Deep is Yin; if accompanied by weak, choppy, wiry, slow Yin pulses, it is double Yin, necessarily indicating Yin excess and Yang deficiency disease. This is balanced viewing. Floating with weak, choppy, wiry, or slow characteristics indicates Yin within Yang; the person has Yang deficiency with Yin Qi hiding within Yang pulses, portending Yang collapse, requiring urgent support of Yang. Deep with large, slippery, or rapid characteristics indicates Yang within Yin; the person has Yin deficiency with Yang pathogenic factors sinking into Yin pulses, portending Yin deficiency complications, requiring careful preservation of Yin. This is oblique viewing. If the five Yang pulse bodies remain unchanged, starting as strong Yang with force and ending as weak Yang without force, one knows Yang is about to perish. Although five Yin pulses may transform into Yang, if they appear suddenly, this is extreme Yin resembling Yang; knowing the reflected light will not last long and embers extinguish easily, this is thorough viewing. There is also viewing of True Yin and True Yang. What is called Yang is the Yang of the stomach region; if the pulse has Stomach Qi, death is avoided. What is called Yin is the pulse of the True Zang organs; seeing True Zang pulses indicates death. However, pathogenic Qi arrives tight and rapid, while grain Qi arrives slow and harmonious; thus, Yin and Yang cannot be determined solely by slow or rapid rates. Among the ten pulses, floating and deep are pulse bodies, large and weak are pulse momentum, slippery and choppy are pulse Qi, moving and wiry are pulse shapes, slow and rapid are pulse rhythm; all are disease pulses, not normal pulses. Ancients said: floating with weakness is Yang deficiency, deep with weakness is Yin deficiency. This states the norm. However, Yin deficiency necessarily manifests Yin pulses, so the more Yang is deficient, the deeper the pulse. If extremely deep then suddenly floating, this is a sign of slight Yang about to escape; if medication causes gradual floating reaching moderate depth, it is auspicious. If suddenly floating, with shortness and chopiness, it is the True Zang pulse of the Lung appearing; if floating, scattered, and large, it is the True Zang pulse of the Heart appearing. Yang pulses are the reverse for Yin deficiency, but the more Yin is deficient, the more floating the pulse becomes. If extremely floating then suddenly deep, this is a sign of True Yin already perished. If tonifying agents cause gradual deepening reaching moderate depth, it is auspicious. If suddenly deepening, or deep with scattering and chopiness, or continuous and about to cease, it cannot be treated further. This is the pulse method of Yin-Yang reversal.
