论曰∶《内经》谓风寒湿三气杂至，合而为痹，其风气胜者为行痹。夫气之在人，本自
流通，所以痹者，风寒湿三气合而为病也。然三气之中，各有阴阳，风为阳气，善行数变，

Commentary states: The *Neijing* (Classic of Internal Medicine) asserts that the mixed invasion of wind, cold, and dampness pathogens combines to form Bi syndrome (obstruction syndrome). When wind pathogen predominates, it is termed Xing Bi (Wandering Bi). Qi in the human body is originally free-flowing; the occurrence of Bi obstruction is due to the combination of wind, cold, and dampness pathogens. Among these three pathogens, each possesses Yin and Yang attributes. Wind belongs to Yang Qi and is characterized by its ability to move rapidly and change frequently; therefore, when wind predominates, Xing Bi occurs. Its clinical manifestations involve pain or numbness wandering up, down, left, and right without fixed retention, following the path of the pathogen, resulting in the obstruction of Qi and Blood circulation. Although the treatment method requires promoting the circulation of Qi and Blood, it is advisable to predominantly use formulas that dispel wind.
