Ping An (Commentary on textual variants): This section from the beginning of the chapter to "pressing it stops immediately" is found in *Ling Shu* (Spiritual Pivot), Volume 5, Chapter 26, "Miscellaneous Diseases". From "sudden abdominal fullness" to the end, it is found in *Su Wen* (Basic Questions), Volume 8, Chapter 28, "Discussion on Excess and Deficiency". Furthermore, from the beginning of the chapter to "Foot Jueyin", it is found in *Jia Yi Jing* (Systematic Classic of Acupuncture and Moxibustion), Volume 9, Chapter 9. From "abdominal fullness with difficulty in defecation" to the end, it is found in *Jia Yi Jing*, Volume 9, Chapter 7.

Fullness and distension in the lower abdomen extending upwards to the stomach and heart region, accompanied by alternating chills and fever, and difficult urination, should be treated by selecting points on the Foot Jueyin Liver Meridian (Zú Juéyīn Gān Jīng). (This indicates that water qi accumulates in the lower abdomen, rising to the epigastrium, causing aversion to cold, alternating chills and fever, and difficult urination, which reflects heat in the lower jiao. Since these symptoms are associated with the Foot Jueyin, its Shu-stream points are selected. Ping An: In *Ling Shu*, "lower abdomen" is written as "small abdomen". In *Jia Yi Jing*, "moving to the stomach" is written as "moving to the chest". *Ling Shu* describes the shivering as "xixi", while *Jia Yi Jing* writes it as "suosuo ran".)

Abdominal fullness, difficulty in defecation, abdominal distension, qi rushing upwards to the chest and throat, with rapid breathing and a "hehe" sound, should be treated by selecting points on the Foot Shaoyin Kidney Meridian (Zú Shàoyīn Shèn Jīng). (These are areas traversed by the Foot Shaoyin meridian, so its Shu-stream points are selected. Some versions suggest this should be the Foot Shaoyang Gallbladder Meridian. Ping An: In *Ling Shu*, there is an additional "yi" before "shang zou". *Jia Yi Jing* lacks the characters for "panting", noting in commentary that "*Ling Shu* contains 'panting'". *Jia Yi Jing* writes "Foot Shaoyin" as "Foot Shaoyang".)

Abdominal fullness with undigested food, empty abdominal distension with constipation, should be treated by selecting points on the Foot Taiyin Spleen Meridian (Zú Tàiyīn Pí Jīng). (Abdominal fullness, indigestion, empty distension, and inability to pass stool are all governed by the Foot Taiyin Spleen Meridian, so its Shu-stream points are selected. Ping An: In *Jia Yi Jing*, the character "fu" is absent after "hua". "Bian bu" is written as "bu neng da bian" in *Ling Shu* and "bu de da bian" in *Jia Yi Jing*. *Jia Yi Jing* writes "Foot Taiyin" as "Foot Taiyang".)

For abdominal pain, puncture the arterial pulses on the left and right of the umbilicus; after needling, press the area, and the pain will cease immediately. If it does not cease, puncture the Qichie (Street of Qi) point; after needling, press the area, and the pain will cease immediately. (Abdominal pain is governed by the Foot Yangming Stomach Meridian (Zú Yángmíng Wèi Jīng); thus, the arterial pulses around the umbilicus belong to the Foot Yangming. Qichie is also an arterial pulse of the Foot Yangming, so it is selected if the pain persists. Ping An: In *Jia Yi Jing*, the characters "yi ci" are absent after "Qichie".)

Sudden severe abdominal fullness that feels hard upon pressure and does not yield, should be treated by selecting the Luo-connecting points of the Foot Taiyang Bladder Meridian (Zú Tàiyàng Pángguāng Jīng). The Luo-connecting points serve as pathways entering the Mu-Alarm points. The Shu-stream point of the Foot Shaoyin is located three cun from the spine, five cun laterally; use a Yuanli needle. (The Foot Taiyang Bladder Meridian and the Foot Shaoyin Kidney Meridian are interior-exteriorly related. The Foot Shaoyin ascends through the liver and diaphragm, dispersing into various abdominal points; therefore, for sudden abdominal fullness, the Luo-connecting points of the Foot Taiyang are selected. The network vessels of the meridians connect to the abundant qi of the Mu-Alarm points. Abdominal fullness can also be treated by selecting the Shu-stream point of the Foot Shaoyin, located three cun apart flanking the spine, taking points five cun lateral to the Shu-stream point, using a Yuanli needle. "Mu" is written as "mu" (curtain) in some versions. Ping An: In *Jia Yi Jing*, the character "tong" (pain) appears after "bao". In *Su Wen*, "Hand" precedes "Taiyang", "Luo-jing" is not repeated, and "ze ren mu zhe ye" is written as "wei zhi mu zhe ye" (is the Mu point of the Stomach). *Jia Yi Jing* writes "qu Taiyang luojing xue zhe ze yi" (if blood is taken from the Taiyang Luo-connecting points, it will stop), omitting the four characters "wu ren mu zhe ye", and adds "you ci" (also puncture) before Shaoyin. Commentary by Wang Bing in *Su Wen* states: "Taiyang refers to the generation of the Hand Taiyang Luo-connecting vessel, so select Zhongwan point, which is the Mu point of the Stomach." New Correction states: "Yang Shangshan's commentary refers to Foot Taiyang; interpretations vary, and it is unclear which is correct.")
