Angampora (Sinhalese: අංගම්පොර , is a form of martial art from Sri Lanka that combines combat techniques, self-defense, sport, exercise, and meditation.
 A key component of angampora is the namesake "angam", which incorporates hand-to-hand fighting, and "illangam", involving the use of indigenous weapons such as the ethunu kaduwa, staves, knives and swords.
 Another component known as "maya angam", which uses spells and incantations for combat, is also said to have existed.
 Angampora's distinct feature lies in the use of pressure point attacks to inflict pain or permanently paralyze the opponent.
 Fighters usually make use of both striking and grappling techniques, and fight until the opponent is caught in a submission lock that they cannot escape.
 Usage of weapons is discretionary.
 Perimeters of fighting are defined in advance, and in some of the cases is a pit.
 With the advent of colonialism over the entirety of the island in 1815, Angampora fell into disuse and was very nearly lost as a part of the country's heritage.
 The British administration prohibited its practice due to the dangers posed by a civilian populace versed in a martial art, burning down any "angan madu" (practice huts devoted to the martial art) found: flouting of the law was punished by a gunshot to the knee, effectively crippling practitioners; Angampora nevertheless survived within a few families, allowing it to emerge into mainstream Sri Lankan culture post-independence.

Kung Fu San Soo (功夫散手) is a martial art based on techniques from all over China, both Northern and Southern Chinese martial arts systems.
 The 5 Family Fist (五家拳) is an important part of San Soo, and is commonly practiced in the Taishan region of the Guangdong province.
 Kung Fu San Soo as taught in China has many traditional forms and isometric exercises in its training regimen.
 Chin Siu Dek (Jimmy H. Woo), the man responsible for bringing Kung Fu San Soo to America, did not believe in the animal styles and hence taught only the 5 family styles (蔡李何佛雄).
 His words were, "We fight like men, not animals."
 The name "Kung Fu San Soo" itself was chosen by Woo to simplify the pronunciation and meaning for American students, rather than using the complete names of the 5 families.
 Kung Fu San Soo originated for use in military combat and uses techniques designed to swiftly disable an attacker.
 Due to the fact San Soo is a practical martial art for self-defense and the techniques are intended for real fight scenarios, there are no competitions or tournaments for San Soo Kung Fu.
