Feng shui (, ) is a Chinese philosophical system of harmonizing everyone with the surrounding environment. It is closely linked to Daoism. The term feng shui literally translates as "wind-water" in English. This is a cultural shorthand taken from the passage of the now-lost Classic of Burial recorded in Guo Pu's commentary: Feng shui is one of the Five Arts of Chinese Metaphysics, classified as physiognomy (observation of appearances through formulas and calculations). The feng shui practice discusses architecture in metaphoric terms of "invisible forces" that bind the universe, earth, and humanity together, known as qi.
