孟少，仲平，季多也。
《内经》以寅、申、巳、亥四孟为一阴一阳也，子、午、卯、酉四仲为一阴一
阳也，辰、戌、丑、未为三阴三阳也。然阳为先，故主虚无变化，轻微而少；阴
为后，故形体安静，重浊而多也。故风火动乱至阳为先，居孟，未甚为少；寒湿
肃静至阴为后，居季，已甚而为多，燥热各得乎中，故居仲而平也。注曰∶气有
多少，是言六气；形有旺衰，言五运也。
诸风掉眩皆属肝木。诸痛痒疮疡皆属心火。
诸湿肿满皆属脾土。诸寒收引皆属肾水。

痉（其井切，似风狂病也，一名曰 尺至切）。积饮（水蓄不散也。）痞（否），肠胃气液血脉否
闭，不能营运，谓之痞也。水谷传化阻隔失常，则曰膈 （音附）。
诸热瞀螈，筋惕悸动，搐搦螈 ，暴喑冒昧，躁扰狂越，骂詈惊骇， 肿疼

The beginning, middle, and end stages correspond to the states of "few," "balanced," and "many," respectively.
The *Huangdi Neijing* (Yellow Emperor's Inner Canon) posits that Yin-Shen-Si-Hai, these four "Meng" (beginning) positions, represent one Yin and one Yang; Zi-Wu-Mao-You, these four "Zhong" (middle) positions, represent one Yin and one Yang; Chen-Xu-Chou-Wei, these three "Ji" (end) positions, represent three Yin and three Yang. However, Yang Qi acts as the pioneer, thus governing voidness and transformation, being slight in nature and few in quantity; Yin Qi follows, thus possessing a quiet form, being heavy and turbid in nature, and many in quantity. Therefore, Wind and Fire, which are turbulent and chaotic, belong to the extreme Yang Qi, occupying the leading position (Meng), not yet reaching extremity, hence they are few; Cold and Dampness, which are solemn and quiet, belong to the extreme Yin Qi, occupying the terminal position (Ji), having reached extremity, hence they are many; Dryness and Heat each occupy their intermediate position, thus residing in the middle (Zhong) and remaining balanced. The annotation states: The abundance or scarcity of Qi refers to the Six Qi (Wind, Summer-Heat, Dryness, Dampness, Cold, Fire); the prosperity or decline of Form refers to the Five Movements (Wood, Fire, Earth, Metal, Water).
Cold, Summer-Heat, Dryness, Dampness, Wind, Fire.
All cases of tremors and dizziness caused by Wind belong to Liver Wood. All cases of pain, itching, sores, and ulcers belong to Heart Fire.
All cases of swelling and fullness caused by Dampness belong to Spleen Earth. All cases of contraction and pulling caused by Cold belong to Kidney Water.
All cases of Qi stagnation and flaccidity syndromes belong to Lung Metal.
(Mental oppression and confusion.) Yu (Stagnation, obstruction.)
All sudden cases of rigidity and stiffness, limb pain and twisting, internal urgency, and tendon contraction belong to Wind (this is Jueyin Wind-Wood, the Qi of the Liver and Gallbladder).
All cases of wheezing, vomiting, and acid regurgitation, sudden diarrhea with tenesmus, muscle spasms, turbid urine, abdominal distension large and drum-like upon percussion, carbuncles, sores, rashes, tumor-Qi, and lymphatic nodules, vomiting and diarrhea Huoluan, mental confusion and swelling, nasal congestion, rhinorrhea, and epistaxis, blood extravasation or hemorrhage, strangury and retention with body heat, aversion to cold and shivering, fright, bewilderment, sadness, manic laughter, delirium, epistaxis, and sweating all belong to Heat (this is Shaoyin Sovereign Fire, the Qi of the True Heart and Small Intestine).

Pi (Obstruction), where Qi, fluids, and blood vessels in the intestines and stomach are blocked, unable to circulate, is called Pi. When the transmission and transformation of water and grain are obstructed abnormally, it is called Ge (Pronounced fu).
