Name and classical tradition
Yingchuang (膺窗) is the “chest window.” 膺 is the front of the thorax; 窗 is the window. It is the last name in the architectural series that the Stomach channel unfolds across the chest: after the gate of ST13, the storehouse of ST14, and the hidden room of ST15, the window arrives. The usual reading is that the point opens the chest and relieves the sensation of oppression.
The Zhenjiu Jiayi Jing (Systematic Classic of Acupuncture and Moxibustion) locates it with the same measure it uses for its neighbor: “膺窗，在屋翳下一寸六分”, one cun and six fen below Wuyi. The regularity of these distances between chest points shows the care with which Huangfu Mi arranged the points of this region. No alternative names are known for it.
