This work was authored by Xu Yanchun of Kuaiji, with subsequent additions by Liu Zongnong of Wuling; both were physicians well-versed in medicine. The entire work consists of fifty volumes, organized by categories, presenting the principles of etiology, syndromes, and treatment in a clear, detailed, and comprehensive manner.

The medical classics such as *Shennong Bencao Jing* (Divine Farmer's Materia Medica), the works of Huangdi and Qibo (Yellow Emperor and Qibo, referring to *Huangdi Neijing*), Yi Yin (referring to *Tangye Jingfa*), Qin Yue Ren (Bian Que, referring to *Nanjing*), and Zhang Zhongjing (referring to *Shanghan Zabing Lun*) are revered for all generations and cannot be altered. Throughout the Jin, Tang, and Song dynasties, there have been eminent physicians. In recent times, Zhang Yuansu rose in the North, said to have received divine inspiration, delving deeply into the profound mysteries of medicine. His second-generation disciple was Li Mingzhi, and his third-generation disciple was Wang Haogu in the South. Zhu Yanshou (Zhu Danxi) privately studied under Ma Shi (Note: Text says "Ma", historically Zhu Danxi studied under Li Dongyuan, but translation follows text strictly or implies a lineage), thereby establishing the orthodox school of medicine. Xu Yanchun and Liu Zongnong further privately studied under Zhu Yanshou. Critics state that Zhang Yuansu represents the "Kingly Way" (Wangdao) among physicians. The Kingly Way takes nourishing the people as its foundation; Zhang Yuansu's methods emphasize strengthening the Spleen and Earth element, which is grasping the fundamental task. This compilation primarily follows the principles of *Suwen*, *Nanjing*, *Jingui Yaolue*, and the school of Zhang Yuansu. If other schools' treatment methods do not contradict these, they are also widely collected and appended. Although TCM practitioners can achieve success by adhering to this approach, if patients also understand these knowledge, they will certainly not be misled by mediocre doctors. Would the benefits of such aid not be significant? Yang Shiqi of Dongli

*Neijing* states: When wind pathogen attacks the human body, it may manifest as cold-heat alternation, cold center, heat center, or hemiplegia. Wind is agile and changes frequently; when its changes reach their extreme, they become other diseases. Historical discussions on injuries to the five Zang organs and Stomach, as well as names of wind diseases, mostly mention sweating and aversion to wind (see detailed text).

Commentary: The discussion on wind clarifies that wind pathogen belongs to external contraction diseases, differing in internal/external, Zang-Fu deficiency/excess, and cold/heat. There is no mention of paralysis, flaccidity, apoplexy, unconsciousness, stiff collapse, spasms, dizziness, slurred speech, or muteness. It was only later that wind disease became confused with flaccidity syndrome (Wei Syndrome).

*Jingui Yaolue* states: Wind disease should present with hemiplegia. When meridians and collaterals are empty, evil pathogens cannot be expelled; the pathogen may be on the left or right. Where the pathogen resides, the muscles relax; where the healthy Qi resides, it becomes tense. Healthy Qi pulls towards the pathogen, causing deviation and inability to move. If the pathogen is in the collaterals, the skin and muscles feel numb; if in the meridians, the limbs are heavy and unable to bear weight; if entering the Fu organs, the person loses consciousness; if entering the Zang organs, speech becomes difficult, and saliva dribbles from the mouth.

*Qianjin Fang* states: Qibo's four major methods for treating stroke are: 1. Pianku (Hemiplegia), half-body paralysis; 2. Fengfei, painless body with limbs unable to grasp or move; 3. Fengyi, sudden unconsciousness; 4. Fengbi, various Bi syndromes resembling wind patterns.

Commentary: Later compilations of formulas and treatments for stroke all follow the theories of *Jingui Yaolue*, Chao Yuanfang's *Zhuzheng Youbing Yuanhou Lun*, and *Qianjin Fang*. However, it is inappropriate to name them based on external wind invasion and treat them identically with internal Wei Syndromes of the five Zang organs. This has been a flaw since ancient times.
