Qi Men Dun Jia is based on astronomical observations, and consists of various aspects of Chinese metaphysics, including the doctrines of Yin and Yang, Five Elements, the Eight Trigrams, the Ten Heavenly Stems and the Twelve Earth Branches, as well as the traditional Chinese calendar, with its twenty-four seasons.

Originally devised to help form military strategy and tactics, Qi Men Dun Jia was in use as long ago as the period of Chinese history known as the Warring States, and is believed by Chinese scholars to have been used at the Battle of Red Cliffs in the defeat of Cao Cao's ship-borne army.

Liu Bo Wen is believed to have secured the throne for the Ming emperor by applying Qi Men Dun Jia to his strategic planning.

Over the centuries of Chinese history, Qi Men Dun Jia grew in popularity and was expanded to include a number of other types of divination, including medical divination, matchmaking, childbirth, travel, personal fortunes, and today includes contemporary applications, most notably, that of business and finance. Today Qi Men Dun Jia proves especially popular in Singapore and other nations of Southeast Asia.
