Feng shui is an ancient Chinese system of aesthetics believed to use the laws of both Heaven (astronomy) and Earth (geography) to help one improve life by receiving positive qi. The original designation for the discipline is Kan Yu (simplified Chinese: 堪舆; traditional Chinese: 堪輿; pinyin: kānyú; literally: Tao of heaven and earth).
Historically, feng shui was widely used to orient buildings—often spiritually significant structures such as tombs, but also dwellings and other structures—in an auspicious manner. Depending on the particular style of feng shui being used, an auspicious site could be determined by reference to local features such as bodies of water, stars, or a compass. Feng shui was suppressed in China during the cultural revolution in the 1960s, but has since seen an increase in popularity, particularly in the United States.
