Zi Collection, Page Position: Upper, Radical: Mouth (kǒu), Page 7, Entry 08 Pronounced pēng (rising tone). Refers to abdominal pain. The "Zhengzitong" states that it is the same as the character "怦". Note: This character is not recorded in character dictionaries but appears in the "Ling Shu Jing" (Classic of Spiritual Pivot) which says: "㤣, abdominal distension and pain," with the annotation "㤣, full." It is similar in form and meaning to the character "恲" in dictionaries like "Yupian" and "Guangyun," and should be considered a variant form of "恲." The explanation in "Zihui" as abdominal pain is incorrect, and the statement in "Zhengzitong" that it is the same as "怦" is unfounded.
