Water Dragon formulas are key feng-shui formulas which show how water should be organised outside a house to provide the maximum benefit. They are usually associated with creating and increasing wealth. This Water Dragon text comes from a collection of key feng-shui texts collected during the reign of the Emperor Ch'ien Lung (Qianlong), by Chang Ping Lin a feng shui master from Fukien in the early 18th century. This text is from an authentic source, which has never previously been available in English. Its formulas, some of which are derived from Yang Kung (Yang Yun Sung, fl. 888 AD), are clear and easy to apply, provided you have an a lo p'an.
