(1) The late Mr. Shen Xinpu, a great-grandson of Duke Duanke, once criticized Wu Jutong for conflating epidemic diseases (Yi Zheng, 疫病) with warm diseases (Wen Bing, 温病). I hold that this is not the only issue. In the opening of his *Treatise on Differentiation of Warm Diseases* (*Wenbing Tiaobian*, 《温病条辨》), he lists: warm diseases include wind-warmth (Feng Wen, 风温), warmth (Wen Re, 温热), epidemic warmth (Wen Yi, 温疫), warm toxin (Wen Du, 温毒), summer-heat warmth (Shu Wen, 暑温), damp-warmth (Shi Wen, 湿温), autumn dryness (Qiu Zao, 秋燥), winter-warmth (Dong Wen, 冬温), and warm malaria (Wen Nue, 温疟), totaling nine categories. This seems comprehensive, yet he fails to realize that his thematic focus is unclear. Conditions where cold pathogen is contracted in winter and manifests in spring are called warm disease; those manifesting after the Summer Solstice are called heat disease; those contracting wind-heat pathogen in winter or spring, initially attacking the Lung, are called wind-warmth; those occurring in winter are also called winter-warmth; those occurring in spring are also called spring-warmth. These are what Ye Tianshi discussed. Heat diseases manifesting after the Summer Solstice are also referred to as summer-heat (Shu, 暑) in the *Neijing* because they occur during the summer season. Thus, Zhang Zhongjing named diseases caused by contracting summer-heat in summer as "Zhong Yue" (Heatstroke/Moye, 中暍). Both "summer-heat" and "moye" refer to heat. To fabricate the term "summer-heat warmth" is most illogical. Furthermore, epidemic diseases should not be treated together with warm diseases; one should take the approaches of Wu Keyang and Yu Shiyu as the standard. That warmth manifests as toxin or malaria are merely sub-categories of warmth. Generally speaking, the more one differentiates, the less clear it becomes.

(2) The subsequent clause states: "For all who suffer from warm diseases, it begins at the Upper Jiao, involving the Hand-Taiyin Lung Meridian." Alas! Has he not read the *Neijing*? Diseases caused by latent qi (Fu Qi, 伏气) originate from within. Only wind-warmth in winter/spring, summer-heat, and autumn dryness begin at the Upper Jiao. If these boundaries are unclear, yet one insists on drawing rigid lines to restrict diseases, errors will inevitably occur upon treatment. When discussing the Three Jiao regarding warm-heat diseases, it does not mean the disease must start in the Upper Jiao and gradually spread to the Middle and Lower Jiao. Latent qi originating internally may cause diseases starting in the Lower Jiao; the Stomach, being a place that stores filth, may see damp-warmth and epidemic toxins starting in the Middle Jiao; summer-heat pathogen carrying dampness may also invade the Middle Jiao. Moreover, summer-heat belongs to Fire, and the Heart is the Fire organ; like attracts like, so pathogens easily invade. Although starting in the Upper Jiao, it cannot be assumed to be solely in the Hand-Taiyin channel.

(3) The fourth clause states: "For Taiyin wind-warmth, warmth, epidemic warmth, and winter-warmth, if chills and aversion to wind/cold appear at the onset, Guizhi Tang (Cinnamon Twig Decoction) should be used." Since Jutong reveres Ye Tianshi, he ought to have carefully examined Ye's clinical cases to formulate his statements. For instance, Case 3 in the "Warm Disease Section" of *Linzheng Zhinan* (Guidelines for Clinical Practice) states: "Warm pathogens enter from above into the Lung. The Lung governs the Qi of the whole body. If Qi stagnates and fails to transform, external cold resembles shivering. The internal depression of warm pathogens must transform into heat." Case 5 in the "Wind-Warmth Section" states: "Wind-warmth enters the Lung, Qi refuses to descend, presenting with external chill and internal heat, which is a sign of Qi depression. Medications used are all mild acrid-cool agents." In *Youke Yaolüe* (Essentials for Pediatrics), the discussion on latent qi external contraction across three seasons is particularly detailed. For spring-warmth cases triggered by external pathogens activating latent heat, one must first use acrid-cool methods to resolve the new pathogen, noting the use of Congchi Tang (Scallion and Fermented Soybean Decoction). The instruction is clear; why willingly deviate and claim to follow Zhang Zhongjing? One should not boast ancestral glory as personal achievement. Mr. Jingyang stated: In warm diseases where latent cold transforms into heat, the essence of Shaoyin has already been depleted. Even with combined new and old pathogens, Guizhi Tang should not be used to assist heat and sever the root. Did Wu never hear this?

(4) The self-note for the first clause in the "Middle Jiao Section" says: "If Lung disease transmits reversely, it goes to the Pericardium; if the Upper Jiao is mismanaged, it transmits to the Middle Jiao; it starts in the Upper Jiao and ends in the Lower Jiao." Alas! This is a predetermined path by Jutong, insisting that warm-heat diseases must follow it. Is there any logic to this? Pathogens invading the Lung, if not resolved externally, naturally transmit downward to the Stomach as the smooth course. Hence, often when the Upper Jiao condition persists alongside the Middle Jiao, it is because the downward transmission failed to proceed smoothly, leading to internal collapse into the Danzhong (Chest Center), which is termed reverse transmission. Zhang Xuguo also misunderstood this principle, claiming: "Fire overcomes Metal, so Lung pathogens transmit back to the Pericardium, hence called reverse." Pathogens coming from the element one controls are minor pathogens; how can they be considered reverse? Did both gentlemen not read the *Nanjing*? Those not starting in the Upper Jiao need not even be mentioned.

(5) The book is titled *Treatise on Differentiation of Warm Diseases*, yet the cholera-like disorders listed are all cold patterns. Therefore, in my youth, presumptuously writing *Treatise on Cholera* (*Huoluan Lun*, 《霍乱论》). Old Man Shen said: Jutong’s writing follows Ye Tianshi. There are supplements unseen by predecessors, such as adding separate clauses for autumn dryness transforming into spasms, showing exquisite reasoning. There are omissions of things seen by predecessors, such as failing to extract the heat pattern of cholera from the Damp-Heat section, thus ignoring heat. Regarding hernia, acute and chronic cases should be treated differently; Mr. Xiangyan had already clarified this, yet Jutong only recognized cold patterns. Mental application varies in depth; even Heaven and Earth are imperfect worlds, let alone humans. He further said: The hernias mentioned by Jutong are mostly acute conditions, while chronic ones are old masses, so warm purgatives can be uniformly used to expel them. Although hernias may persist for years, they form有形 (have shape) when gathered and disappear无形 (formless) when dispersed; they do not truly exist as solid masses like blood stasis in the abdomen. Also, for dry cholera, swallowing juice pounded from raw taro brings life, far superior to salt water-induced vomiting. For early-stage summer-heat skin sores, applying pounded loofah juice or lotus petals is excellent, without needing narcissus root.

(6) Clause 84 of the "Middle Jiao" states: "For Shaoyang malaria resembling Shaoyang syndrome, Xiaochaihu Tang (Minor Bupleurum Decoction) should be used." What does this have to do with warm-heat, yet it is indiscriminately included? Old Man Shen said: Ye Tianshi knew that summer-damp seasonal malaria differs significantly from wind-cold typical malaria. Integrating sage teachings, he focused on clearing and resolving, showing superior insight. Xu Lingtai (Xu Huixi) repeatedly slandered him for not using Chaihu, displaying rigid adherence to ancient texts. If even Mr. Xu acted thus, how much more so others? Alas! Old Man Shen was nine years my senior, our friendship was deepest, his character and scholarship were outstanding, truly an ancient gentleman. He once proofread *Wenre Jingwei* (Classic Coordinates of Warm-Heat) for me. Poor and childless, his grave is now overgrown. His unpublished manuscripts were occasionally found among my drafts; I append a few clauses here to show his discerning eye and sincere expression.

(7) Dingfeng Zhu (Stabilizing Wind Pearl) in the "Lower Jiao Section" is greasy, turbid, and cloying; even patients with weak stomachs find it hard to swallow. If administered for collapse with convulsions and hiccups, it would hasten danger.

(8) Clauses 24 to 26 discuss treatments for latent winter cold manifesting as spring-warmth, yet wrongly claim these are treatments for warm-heat/epidemic warmth transmitting from Upper/Middle to Lower. This is nonsense.

(9) Self-note for Clause 42 claims that since Song and Yuan dynasties, people did not understand that Zhang Zhongjing’s book was specifically for cold damage, implying Wu never read *Shanghan Lun*. Dozens have annotated *Shanghan*, all viewing it as exclusively about cold damage, leading to fragmented interpretations. Examining the five qi causing disease—wind, cold, warmth, moye, damp—ancients called them all cold damage. Thus, *Nanjing* says "Cold Damage has five types," and Zhang Zhongjing named his book accordingly. Such unclear major principles make rash authorship unacceptable.

(10) Clause 51 discusses Yin Chui (noisy flatulence) due to phlegm-damp obstructing Qi, a concept indeed unmentioned by predecessors.

(11) Clause 55 elucidates the function of Can Sha (Silkworm Feces) with precision, making it my primary herb for treating cholera.

(12) Wu’s book merely intersperses cases from Ye’s *Zhinan* on warm-heat and summer-damp. Regrettably, he failed to trace origins to *Neijing*, *Nanjing*, and *Shanghan Lun*, nor did he cross-reference Ye’s *Wenre Lun* and *Youke Yaolüe*. Thus, although claiming to innovate on Ye, he missed its essence. The appended formulas are poorly edited and selected improperly, prompting my compilation of *Wenre Jingwei*.

(13) The last three volumes, including miscellaneous essays, solving difficult childbirth, and solving difficult pediatrics, are worthy of transmission, far surpassing the Three Jiao differentiation. Among miscellaneous essays, only the statement "for cholera with inability to vomit or purge, treat with bitter, acrid, aromatic, and hot herbs" is debatable. Many points in the differentiation are questionable. I have outlined the major issues above so readers do not follow the crowd blindly.
