None of the versions contains the character "Pian" (Chapter).
Qi rising causing Shang Ge syndrome (a condition where food is vomited immediately after ingestion). The *Jia Yi Jing* records that below the characters "Shang Ge," the characters "Shang Ge" are repeated. Ma Yun states that this refers to Ge syndrome, which has upper and lower distinctions, but particularly elaborates on the meaning of Xia Ge (Lower Ge).
The term "Ge" refers to the diaphragm membrane. Its anterior aspect aligns with the Jiutui point, and its posterior aspect aligns with the eleventh thoracic vertebra. Its function is to shield and isolate turbid Qi, preventing it from steaming upward to affect the Heart and Lungs. However, some diseases occur above the Ge, caused by rebellious Qi. Food and drink enter and are immediately expelled. Other conditions occur below the Ge, caused by intestinal parasites. Food and drink remain for a Zhou Shi (a traditional time unit, approx. two hours) before being expelled. The Yellow Emperor explained Shang Ge clearly but was obscure regarding Xia Ge. Zhang Yun notes: "Shi" means "Zhou Shi." This commentator observes that Shang Ge and Xia Ge essentially refer to Ge Shi syndrome (dysphagia or regurgitation).
Discomfort due to excessive joy or anger causes pathogenic Qi to remain in the body. Both the *Jia Yi Jing* and *Liu Zhu* versions write the character as "Liu" (flow/remain). Zhang Yun argues that damaging Stomach Qi leads to Yang deficiency and cold. Fluids flow into the intestines; because the parasites become cold and immobile, they gather in the Xia Wan (lower stomach), causing fullness in the intestines and stomach. Wei Qi here refers to Spleen Qi. Since Spleen Qi cannot circulate and transport effectively, pathogenic Qi can gather and reside there.
When a person eats, the parasites move upward to feed... heat appears on the skin overlying the abscess. In the *Jia Yi Jing*, "Ji Er" is written as "Chen Er." The phrase "its abscess is external" is interpreted as "the abscess is outside the Wan (stomach area)," both interpretations being acceptable. Zhang Yun states that "Yong" (abscess) is synonymous with "Yong" (obstruction/blockage). As stated in the *Lun Ji Zhen Chi Pian*: "Slight swelling in the eye sockets," the meaning is similar here. Cold parasites, smelling food, prefer to seek it upward. Upward movement allows pathogenic Qi to reside there, accumulating in vacuities, leading to an abscess in the lower Wan. Because the meridians' Qi does not flow smoothly, food enters and is later expelled. "Inside and outside the tube" refers to the lower Wan. Pathogenic Qi hides deep within, so heat manifests on the skin and flesh.
Gently pressing the abscess... grain then descends. In the *Jia Yi Jing*, "Wu" is written as "Hu," "Xian" as "Suan," and the character "Ge" follows "Nai Xia." Zhang Yun suggests this involves observing the pathway of Qi to perform acupuncture. First, shallowly puncture nearby areas where Qi reaches, gradually inserting the needle deeper to drain circulating pathogenic Qi. Then, puncture the primary acupoint of the diseased area to extract the root of the accumulation. However, this should be done only two or three times and must not be excessive. Deep puncture for deep-seated pathogens; shallow puncture for superficial pathogens. After needling, apply moxibustion or hot compresses daily to maintain warmth. This warms the interior Qi, causing pathogenic Qi to disperse naturally. "San" refers to the combination of threes; "Wu" refers to the pairing of fives. Regarding diet, respiration, and daily life, one must carefully consider appropriateness, observe taboos to prevent internal injury, and if injured, practice tranquility and non-action to nourish Zheng Qi (Upright Qi). When Zheng Qi flows, pathogenic Qi may dissipate. Ge syndrome is notoriously difficult to cure; thus, such strict precautions are necessary. "Xian" (Salty) transforms via Water, moistening and softening hardness; "Ku" (Bitter) transforms via Fire, warming the Stomach. Thus, both facilitate the descent of grain. Jian An notes: The *Jia Yi Jing* posits that this chapter discusses pathogenic Qi gathering in the lower Wan, causing internal Yong. The next chapter discusses the diagnosis of Wei Wan Yong. Zhi's commentary also interprets "Yong" literally. Based on mentions of "heat on skin overlying Yong" and "large Yong suppurating," it seems this describes Ge Shi caused by internal Yong. The aforementioned "Shang Ge" belongs to the Five Ge discussed in works like Chao Yuanyang's *Bing Yuan*. The so-called "Xia Ge," where food is expelled after a Zhou Shi (*Xie Qi Zang Fu Bing Xing Pian* states: rapid Spleen pulse indicates Ge Zhong, food/drink enters and returns, followed by frothy saliva; modern Ge syndrome need not be so severe; likely ancient terms for vomiting/regurgitation were collectively called Ge, hence Yu Tun said Ge is also Fan Wei). Parasite-induced and Yong-induced cases are distinct types of Ge syndrome outside the Five Ge. Ma Shi and Zhang Jiebin read "Yong" as "Yong" (blockage); while semantically passable, the intent remains unclear. Furthermore, Zhang's recorded case involves ordinary Ge syndrome, distinct from the Xia Ge described in this chapter. Zhi interprets "Yong" as internal Yong, but his annotation is confused and thus unreliable. *Yi Shuo* cites the *Ji Feng Fang*: "Ye Ge syndrome is a matter of Shen Yi (spiritual intent) and Qi." It advises patients to observe internally and externally calmly, delegating all strenuous mental tasks to others, so that medication becomes effective. This aligns with the principle of "tranquility and non-action" in this section.
