Shānggǔ (汤谷) is a mythical place from ancient Chinese cosmology and classical texts like the Classic of Mountains and Seas (Shānhǎi Jīng). Literally, tāng means 'boiling' or 'scalding hot water', and gǔ means 'valley'—together evoking a radiant, steaming valley where the sun rises each day. It symbolizes the easternmost edge of the world, the sacred origin point of light and renewal, often associated with the ten suns (crows) that rested there before their daily journey across the sky.

The term appears almost exclusively in literary, poetic, or mythological contexts—not in modern geography or daily speech. It carries strong connotations of antiquity, cosmic order, and cultural symbolism rather than physical location. While it shares the character gǔ (valley) with real places, Shānggǔ is never used to refer to an actual valley today; its meaning is entirely rooted in classical imagination and ritual cosmology.
