Regarding the discussion of Spring-Warmth diseases (Chunwen), only Yu Jia Yan and Ye Tianshi (Yuan Gong) provided precise and rigorous analyses. Yu Jia Yan categorized them into three examples: "Winter injury by Cold, leading to Warmth disease in Spring" as one example; "Winter failure to store Essence, leading to Warmth disease in Spring" as another example; and cases where both Cold injury and Essence depletion occur simultaneously in Winter, manifesting together in Spring, as a third example. By presenting these three examples, he discussed Warmth diseases and detailed their treatments. Ye Tianshi's discussions focused on clinical manifestations of Wind-Cold injury in Spring, distinguishing how to diagnose and treat based on the Three Yang meridians and the Three Yin meridians respectively. Observing the theories of these two masters, one can say they are as clear as pointing at something with a finger. However, adhering solely to Yu Jia Yan while rejecting Ye Tianshi, or vice versa, leaves later generations without a standard to follow. In fact, Yu Jia Yan's theory follows classical teachings divided into three categories, emphasizing latent Qi (Fuqi); Ye Tianshi's theory focuses on clinical signs of new-onset Wind injury, emphasizing new acquisition (Xingan). In summary, Spring-Warmth disease arises from slight Cold acquired in Winter, lying dormant in the skin and muscles without immediate eruption, or due to Winter failure to store Essence, lying dormant in the Shaoyin meridian without immediate eruption. It waits until the following Spring when external Cold triggers the latent Qi to erupt. This corresponds to the classic saying: "Winter injury by Cold leads to Warmth disease in Spring; Winter failure to store Essence leads to Warmth disease in Spring."

At the initial stage, symptoms include pain in the head and body, aversion to cold, fever, anhidrosis, cough, thirst, floating white tongue coating, and pulse that is abundant upon light palpation, either wiry or tight, and slippery or rapid upon heavy palpation. At this stage, Acrid-Warm Exterior-Resolving Method (Xin Wen Jie Biao Fa) should be used first. If the tongue coating becomes dry, yellow, or scorched black, it indicates that Heat has reached the Stomach, and Cool Interior-Resolving Method (Liang Jie Li Re Fa) should be applied immediately. If the tongue is crimson, teeth are dry, delirium occurs, and consciousness is clouded, it indicates that Heat deeply resides in the Ying (Nutritive) level of the Yangming meridian, and Clear Heat and Detoxify Method (Qing Re Jie Du Fa) should be used to preserve Body Fluids (Jinye). If convulsions of the limbs occur with a wiry and rapid pulse, it signifies Extreme Heat generating Wind, requiring Heat-Purging and Wind-Extinguishing Method (Que Re Xi Feng Fa). If the patient is confused, unconscious, mute like corpse rigidity, it indicates Evil has penetrated the Pericardium, requiring Heat-Expelling and Orifice-Opening Method (Qu Re Xuan Qiao Fa). The transformations of Spring-Warmth are endless; the key lies in adapting to changes during clinical practice.

Wind-Warmth (Fengwen) disease occurs when the Jueyin Wind-Wood ruling period of Spring begins, coinciding with the initial interaction of Shaoyin Ministerial Fire. Chen Pingbo stated that Wind-Warmth is common in Spring and Winter, particularly when Wind dominates in Spring and early Winter is warm and windy. This is actually incorrect. One must not confuse Winter-Warmth (Dongwen), characterized by heat, thirst, and cough in Winter, with Wind-Warmth. Even according to the Six Qi theory, if Wind-Warmth exists in Winter, it should be around the Great Cold solar term; referring to "early Winter" is inappropriate. Tracing the origin of Wind-Warmth, it resembles Spring-Warmth, also caused by Winter Cold that did not erupt immediately. In individuals with Kidney deficiency, the pathogenic Qi lies dormant in the Shaoyin meridian; in those who overwork, it lies dormant in the muscle interstices. It requires Spring Wind to trigger the latent Qi to erupt. Symptoms include headache, aversion to wind, fever with spontaneous sweating, cough, thirst, slightly white tongue coating, and floating, rapid pulse. Acrid-Cool Exterior-Resolving Method (Xin Liang Jie Biao Fa) should be employed. If complications such as crimson tongue with yellow coating, delirium, or limb convulsions arise, treatment can follow the methods for Spring-Warmth complications.

A question was raised: Spring-Warmth is triggered by Cold activating latent Qi, initially presenting with aversion to cold and no sweat; Wind-Warmth is triggered by Wind, initially presenting with aversion to wind and sweating. Are these not two different paths? How can the same treatment apply? The answer is: Although the newly acquired pathogens differ, the latent Qi is the same. Therefore, various complications can be treated similarly. It is crucial to distinguish between those suffering from overwork and those who failed to store Essence in Winter. Gradual worsening suggests overwork; immediate fluid damage and rapid complication suggest failure to store Essence. For all Warmth diseases, preserving Body Fluids is paramount. For Yin-deficient patients, nourishing supplementation is essential. Another question asked: Why not follow Zhang Zhongjing's teachings as the standard for Wind-Warmth? The current text does not mention symptoms like floating pulse in both Yin and Yang positions, spontaneous sweating, heaviness of the body, excessive sleepiness, snoring breath, or difficulty speaking. Is this not contradicting Zhang Zhongjing? The response is: Zhang Zhongjing described complications resulting from misdiagnosis/treatment of Wind-Warmth, which are not typical presentations. What are the typical presentations? When Taiyang disease presents with fever, thirst, and no aversion to cold, it is Warmth disease, which is the typical presentation. Regarding Chen Pingbo's twelve points on Wind-Warmth, attributing it to sudden seasonal Qi affecting Lung and Stomach, versus Wu Jutong's Sanjiao differentiation within his Warmth categories: Which is correct? The answer is to always follow the *Neijing* principle: "Winter injury by Cold leads to Warmth disease in Spring." This accommodates both ancient and modern contexts. If Lung/Stomach symptoms appear, treat Lung/Stomach; if Sanjiao symptoms appear, treat Sanjiao. Do not rigidly adhere to fixed definitions. Finally, since both Spring-Warmth and Wind-Warmth involve latent Qi, is it acceptable for modern physicians to diagnose any Spring fever/cough without thirst as Wind-Warmth? Yes. Spring wind comes from the East, bringing thawing warmth; calling it Wind-Warmth is acceptable. Its initial treatment remains within the scope of Acrid-Cool Exterior-Resolving Method.
