Originating in southern China, Yau Kung Mun (occasionally rendered Yau Kung Moon or Yau Kung Mun Kung Fu) is a traditional Chinese martial art. Its exhaustive system of techniques includes grappling, striking, joint locks, throws, and weaponry, among others.

Yau Kung Mun is a martial art that integrates components from a multitude of disciplines, such as Southern Shaolin Kung Fu, Hung Gar, and Choy Gar. The name "Yau Kung Mun" is derived from the Chinese characters "Flexible Power Style" and "Flexible Gong Style," which signifies the combat style's emphasis on adaptability and fluidity.

Yau Kung Mun practitioners engage in sparring, conditioning exercises, forms (sequences of movements), and the application of techniques. Yau Kung Mun, similar to numerous traditional Chinese martial arts, emphasizes fundamental techniques including correct form of movement, mental calmness, regulation of breathing, and the development of internal energy (Qi or Chi).

In addition to physical techniques, Yau Kung Mun training emphasizes the development of mental discipline, concentration, and character. Diverse schools throughout the world teach Yau Kung Mun, each with its own lineage and interpretation of the discipline.

The art is frequently transmitted orally and through hands-on instruction, wherein educators place significant importance on safeguarding its extensive historical and cultural legacy. .
