三戦 is a title that literally means “three battles/conflicts/wars.”

三戦 is often figuratively used to relay the idea of a battle to unify the mind, body, and spirit.

Original usage likely comes from Fujian province in Southern China (just across from Taiwan).

This title is used in various schools such as Okinawan Karate, Uechi-Ryū, Gōjū-Ryū, Fujian White Crane, and Five Ancestors among others.

南派螳螂 can be translated literally as “Southern School Praying Mantis” or “Southern Style Praying Mantis.”

Despite its name, the Southern Praying Mantis style of Chinese martial arts is unrelated to the Northern Praying Mantis style. Southern Praying Mantis is instead related most closely to fellow Hakka styles such as Dragon and more distantly to the Fujian family of styles that includes Fujian White Crane, Five Ancestors, and Wing Chun.

This style of martial arts focuses more on fighting skills rather than aesthetics.

Of course, you already knew that if you were looking for this term.

Note: This title can be pronounced and does have meaning in Korean but only to Koreans familiar with Chinese martial arts.
