This Chinese Feng Shui God of Wealth, Tsai Shen Yeh, rides on a fearsome tiger. His robe is made of dragon skin and he carries a gold ingot,  his symbol of wealth and Taoist accomplishment, and a sword, his protection from evil wrongdoers.
This God is not a god to be worshipped.  Rather, he is used as a symbol of wealth and, hopefully, an attractor of wealth and gold. He can often be seen in the shops of Chinese business owners and, in homes, right at the main door.   
Feng shui or fengshui (Simplified Chinese: 风水; Traditional Chinese: 風水; Pinyin: fēngshuǐ; IPA: [fɤŋ ʂueɪ] listen (help·info)) is the ancient Chinese practice of placement and arrangement of space to attempt to achieve harmony with the environment that has its origins from Taoism. The practice is estimated to be more than three thousand years old.
Proper Feng Shui is a set of general guidelines for the creation of beautiful architecture and comfortable interior decoration not superstition as it has become for some.
"Feng shui" literally means "wind water" in Chinese. Amongst the various anglicised pronunciations of it is IPA: [fɛŋ ʃuːi] listen (help·info). The same Chinese term 風水 is also used in Japan and Korea, where it denotes the same meaning and is called fūsui in Japan and pung-su in Korea.
Traditional ("classical") feng shui is a Chinese esoteric discipline that addresses the design and layout of cities, villages, dwellings, and buildings in order to harness beneficial qi from one's surroundings. Feng Shui addresses the Yang aspect (living) but can also be applied to the Yin aspect -- as seen in the careful construction of graves and tombs. Rules for yang dwellings differ from those applied to "yin houses" (houses of the dead).
Feng shui was labeled geomancy by 19th-century Christian missionaries to China; however, geomancy and feng shui differ widely in their scope, aims, and means. The name Feng Shui literally means "Wind Water". The Book of Burial says "The Qi disperses with the Wind and collects on the boundaries of Water," hence the name.
Traditional feng shui uses a specialized compass called a Luopan, and a comprehensive array of calculations involving mathematical iterations. It has foundation texts, core theories and methods, and an impressive past based on archæological discoveries and the work of archæoastronomers.
Traditional feng shui schools can be segregated into two broad groups: San He (Three Harmonies) and San Yuan (Three Cycles). The former emphasizes the effect of surrounding landforms while the latter gives more weight to the factor of time.
