The discussion on Jiaoxie (Foot Qi, a condition characterized by swelling, weakness, and numbness of the legs) in the *Qianjin Fang* is placed before discussions on various wind diseases, which is well-founded. Although there are many treatises and prescriptions for this disease, few can accurately identify it; some detect it too late, while others hesitate without resolution, resulting in half of the patients dying unnecessarily. This is indeed not an exaggeration. For any such syndrome, urgent treatment is most appropriate. If delayed, the pathogen will enter the abdomen and attack the five zang organs, rendering even miraculous elixirs ineffective. Furthermore, other conditions arising from long-term illness, such as difficulty in urination and defecation, distension and fullness, or food stagnation, may be treated separately. The principle is to first treat the new acute condition, after which the chronic condition will likely resolve; treating everything simultaneously is also acceptable.
