According to the *Qianjin Fang* (Prescriptions Worth a Thousand Gold): Whenever a heat sore appears and immediately produces white pus, it is what is commonly known today as "Nongke Chuang" (Pustular Impetigo). This condition begins superficially, exuding only yellow fluid, and is named "Fei Chuang" (Greasy Sore), also called "Huang Lan Chuang" (Yellow Rotting Sore). Initially resembling Fei Chuang, it tends to appear on the hands and feet, often symmetrically. It fluctuates with the lunar cycle (waxing and waning), accompanied by pain, itching, and skin fissures. Its severity varies with the seasons, improving or worsening accordingly. Severe cases are termed "Gan Chuang" (Ulcerative Sores); treatment methods have been described in the section on Scabies.
