Zhang qi (miasma) is found only in the southeastern regions. Generally, the Lingnan region has low-lying and damp terrain, with much fog and little wind. Moreover, it is often warm in winter, causing the yang qi within yin to be insecure; conversely, it is cool in summer, making the yin evil within yang prone to injuring the body. Therefore, those who do not take care of themselves and indulge in desires or excessive labor are extremely susceptible to contracting this disease, resulting in symptoms such as fever, headache, vomiting, and abdominal distension. Generally, severe cases constitute Shanghan (Cold Damage), while mild cases constitute Malaria. However, when these diseases occur in Lingnan, they are all referred to as Zhang. In regions where yang qi floats outward, there must be true cold internally and false heat externally; in individuals with insecure yin qi, although there are external pathogenic signs, there must be deficiency internally. This is the general situation regarding zhang epidemics in Lingnan. However, I have not personally visited that place, so this is merely an educated guess. Upon reviewing the discussions by various authors, I find them mostly reasonable, which confirms that my words are not false. I have carefully recorded them below for reference, hoping that clinicians will have no confusion and patients will have support. Furthermore, upon careful examination of these discussions, they are already quite detailed. However, I am concerned that their use of tonification methods is not exhaustive. If one encounters a case of severe internal injury and deficiency complicated by this disease, which is critical or difficult to cure, one must refer to and combine the treatment methods from the preceding Plague section. Only then might there be hope for benefit.
