bubble_chart Etymology

"Ju" (巨), big; "xu" (虛), void, empty; it refers to the large gap between tibia and fibula bones of lower leg.Suwen-Zhenjie Pian: "Juxu is the depression that appears when foot is raised." To distinguish it from Shangjuxu (ST37), where "Shang" (上) refers to upper, Qianjin Yifang adds the character "Xia" (下, lower) before it. In Lingshu-Benshu, it is referred to as "Juxu Xilian" (巨虛下廉), which carries the same meaning.
