Feng Shui prides itself on thinking that the land includes Chi. The work Chi has to do with energy. Back in ancient times, the local Chinese people claimed that the energy of the land would be good or bad for others.
Feng Shui comes from the Taoist ideals in order to deal with nature. Taoism deals with religious and philosophical beliefs. Taoism has a strong influence in Asia.
Taoism is also responsible for birthing yin and yang concepts. Yin and yang deal with opposite aspects of a phenomenon or comparing two phenomena. They represent quality in regard to correspondence which is found in most areas of Chinese science and philosophy. An example of this would be ancient Chinese medicine.
