Ryū Ryū Ko, also known as Liu Long Gong, was a Chinese martial artist who most likely practiced the Fujian White Crane style of Kung Fu. His most notable students included many of the founders of different Okinawan martial arts which later produced Karate. These students included Higaonna Kanryō who founded Naha-te which became Gōjū-ryū. The kata Sanchin, taught in Gōjū-ryū and many other Naha-te based styles of Karate, was originally taught by Ryū Ryū Ko.

Karate (空手), also karate-do , is a martial art developed in the Ryukyu Kingdom. It developed from the indigenous Ryukyuan martial arts under the influence of Chinese martial arts. While modern karate is primarily a striking art that uses punches and kicks, traditional karate also employs throwing and joint locking techniques. A karate practitioner is called a karate-ka (空手家).
