Chinese sun and moon mirrors water. (Laufer 1915: 221-222). Owing to the similarities of Chinese "yangsui" and "fangzhu" mirrors with Indian "sūryakānta" and "candrakānta" stones, Tang (1935) proposes a trans-cultural diffusion from China to the Mughal Empire. Chinese sun and moon mirrors The yángsuì 陽燧 or sun-mirror was an ancient Chinese burning-mirror that concentrates sunlight to ignite tinder and the fāngzhū 方諸 or moon-mirror was a device that collects nighttime dew by condensation.

The relative positions and numbers of yin and yang lines within the trigrams determines the meaning of a trigram, and in hexagrams the upper trigram is considered yang with respect to the lower trigram, yin, which allows
