六经之所以区分手经和足经，是因为以足经为本，手经为标。例如足厥阴风木之肝与足少阳相火之胆互为表里。
至于常度而长，关上厥阴口。太阳密移之至太阴之至（一云浮在泉曰北少阴天则为太不）。
左手关前一分为人迎脉，用以候察寒、暑、燥、湿、风、热等邪气中伤于人。这些邪气皆从脉络而入，以迎纳之。
所以说，风邪喜……故不另作论述，以此类推：风邪当自少阳经传入，湿邪当自阳明经传入，暑邪当自三焦传入，寒邪自太阳经传入。所以经文说……皆……者……皆呈现弦、浮、散的脉象。弦脉是足少阳经的脉象；浮脉是伤风的脉象；散脉是病势已至的脉象。其症状表现为身热、恶风、自汗、项强、筋满。
手少阳经伤于暑邪，右手尺中与寸口人迎脉，皆呈现洪、虚、数的脉象。洪脉是手少阳经的脉象；虚脉是伤暑的表现；数脉是病情增重的表现。其症状表现为身热、恶寒、头痛、状如伤寒、烦渴。
足太阴经伤于湿邪，右手关上与人迎脉，皆呈现濡、细、沉的脉象。濡脉是足太阴经的脉象；细脉是湿邪的脉象；沉脉是病邪深着的表现。其症状表现为身重、脚弱、关节烦疼、冷痹、胀满。
足少阴经伤于寒邪，左尺中与寸口人迎脉，皆呈现沉、紧、数的脉象。沉脉是足少阴经的脉象；紧脉是寒邪的脉象；数脉是病邪传变的表现。其症状表现为口燥、舌干而渴，皆恶寒反热、倦怠。
足厥阴经伤于风邪，左关上与人迎脉皆呈现弦、弱、急的脉象。弦脉是足厥阴经的脉象；弱脉是风邪的脉象；急脉是病变的表现。其症状表现为自汗、恶风而倦、小腹急痛。
手厥阴心包经伤于暑邪，左右尺中与寸口人迎脉，皆呈现沉、弱、缓的脉象。沉脉是心包经的脉象；弱脉是伤暑的表现；缓脉是病势倦怠的表现。其症状表现为往来寒热、状如疟疾、烦渴、眩晕、背寒、面垢。
这是分布六经感受外邪的情况。除燥热之外，现在叙述这两种气（风、暑/湿等），作为征兆。如果病邪发生传变，自然应当根据六经别论中所受的损伤，随经论述症状并施治。或者燥热伤害心肺，应当根据经络推明理例进行调治。如果是四气兼并，六经交错，也应当随其脉证，审慎辨别处理。或先或后，或合或散，在络在经，在表在里。四季的变化，脉象与之相应。气候随着时令变化，自然与脉期相符。微妙之处在于脉诊，不可不仔细考察。考察脉诊有纲纪，从阴阳开始。起始的原因，也从阴阳产生。说的就是这个道理。
The reason why the Six Channels (Liu Jing, 六经) are distinguished into Hand and Foot meridians is that the Foot meridians serve as the root (Ben, 本), while the Hand meridians serve as the branch (Biao, 标). For instance, the Foot Jueyin Wind-Wood Liver (Zu Jueyin Gan, 足厥阴肝) and the Foot Shaoyang Ministerial-Fire Gallbladder (Zu Shaoyang Dan, 足少阳胆) form an interior-exterior relationship.
Regarding the standard measure and length, Guan (Cun-Guan-Chi position on the wrist) Jueyin mouth. Taiyang moves densely to reach Taiyin's arrival (One cloud floats in the underground, said North, Shao Yin Heaven then becomes Tai not).
The point one division before the Guan on the left hand is called Yingying (Human Welcome pulse), used to observe how Cold, Summerheat, Dryness, Dampness, Wind, and Heat pathogenic factors injure the human body. These pathogens all enter through the collaterals and vessels, being welcomed and received by this pulse site.
Therefore it is said that Wind favors... thus no separate discussion is made; by analogy: Wind pathogen should enter from the Shaoyang channel; Dampness pathogen should enter from the Yangming channel; Summerheat pathogen should enter from the Sanjiao (Triple Burner); Cold pathogen enters from the Taiyang channel. Thus the classic states... all... those... all present Xian (Wiry), Fu (Floating), and San (Scattered) pulses. The Xian pulse is the pulse of the Foot Shaoyang channel; the Fu pulse is the pulse of Wind injury; the San pulse indicates the disease has arrived. The symptoms manifest as fever, aversion to wind, spontaneous sweating, stiffness of the neck, and fullness of the sinews.
When the Hand Shaoyang channel is injured by Summerheat, both the Chi position and Yingying pulse on the right hand present Hong (Surging), Xu (Deficient), and Shu (Rapid) pulses. The Hong pulse is the pulse of the Hand Shaoyang channel; the Xu pulse indicates Summerheat injury; the Shu pulse indicates worsening of the disease. The symptoms manifest as fever, aversion to cold, headache, resembling Taiyang syndrome, irritability, and thirst.
When the Foot Taiyin channel is injured by Dampness, both the Guan position and Yingying pulse on the right hand present Ru (Soggy), Xi (Fine), and Chen (Deep) pulses. The Ru pulse is the pulse of the Foot Taiyin channel; the Xi pulse is the pulse of Dampness; the Chen pulse indicates the pathogen is entrenched. The symptoms manifest as heaviness of the body, weakness of the legs, painful and vexing joints, cold bi-syndrome (painful obstruction), and distension/fullness.
When the Foot Shaoyin channel is injured by Cold, both the Chi position and Yingying pulse on the left hand present Chen (Deep), Jin (Tight), and Shu (Rapid) pulses. The Chen pulse is the pulse of the Foot Shaoyin channel; the Jin pulse is the pulse of Cold; the Shu pulse indicates transmission of the disease. The symptoms manifest as dry mouth, dry tongue with thirst, aversion to cold with counter-heat, and fatigue/lack of strength.
When the Foot Jueyin channel is injured by Wind, both the Guan position and Yingying pulse on the left hand present Xian (Wiry), Ruo (Weak), and Ji (Rapid/Tense) pulses. The Xian pulse is the pulse of the Foot Jueyin channel; the Ruo pulse is the pulse of Wind; the Ji pulse indicates pathological change. The symptoms manifest as spontaneous sweating, aversion to wind with fatigue, and acute pain in the lower abdomen.
When the Hand Jueyin Pericardium channel is injured by Summerheat, both the Chi positions and Yingying pulse on the left and right hands present Chen (Deep), Ruo (Weak), and Huan (Slow/Lax) pulses. The Chen pulse is the pulse of the Pericardium channel; the Ruo pulse indicates Summerheat injury; the Huan pulse indicates disease-related fatigue. The symptoms manifest as alternating chills and fever, resembling Malaria (Nue, 疟), irritability, thirst, vertigo, coldness of the back, and a greasy appearance of the face.
This describes the distribution of the Six Channels receiving external pathogens. Excluding Dryness and Heat, we now narrate these two qi (factors) as omens/signs. If the disease transmits, it naturally follows the injuries described in the separate discussions of the Six Channels, treating according to the channel and presenting symptoms. Or if Dryness and Heat damage the Heart and Lungs, one must deduce the principles based on the channels for regulation and treatment. If the Four Qi (pathogens) combine and the Six Channels interweave, one must also follow the pulse and symptoms to examine and distinguish carefully. Whether first or later, combined or dispersed, in collaterals or channels, in exterior or interior. The movements of the four seasons correspond with the pulse. Climate changes with time, naturally aligning with the pulse period. The subtlety lies in the pulse, which must not be neglected. Examination of the pulse has its discipline, starting from Yin and Yang. The origin of the start arises from Yin and Yang. This is what is meant.
