Point name meaning:

The character (tiān) can be considered as a reference to the vertex of the head, while the pictograph (tōng) may be construed as indicating the network vessel that runs from BL-7 to Hundred Convergences (GV-20); hence the rendering Celestial Connection.

Rendered as Unblock Heaven, the name reflects this point’s function of clearing the nose. Heaven (天) here refers to the uppermost viscus, the lung, which opens at the nose. See acupoint names: origins, meanings, and translations.
