The pyong ahn hyeong are a series of five forms cognate in many ways to the pinan kata series of karate. They were developed by Itosu, an Okinawan practitioner of Te and mentor of Funakoshi Gichin. These forms were designed as training forms for Kong Sang Koon (Kusanku). For a more comprehensive description of these hyeong see Pinan K
Pyong Ahn Ee Dan
This hyeong is typically one count/technique longer than the other low-rank forms, due to one of its techniques, a side kick, which is performed in two counts, the first to set up and the second to deliver. It is also one of the few low-level hyeong to have a yell on the last move. The most-often used technique in this hyeong is the middle knife-hand block.
The phrase “pyong ahn” is often translated as “well-balanced” and “peaceful.” These forms are usually taught after the gicho hyeong. These forms were reorganized from their original style(called “Jae-Nam”) in approximately 1870 to their present style. These forms show the influence of the southern China martial art style.
The Pyung Ahn hyeong are often referred to as the “turtle forms”. The turtle is well balanced, calm, and peaceful (pyung) and with its shell as its major means of defence, the turtle likely feels safe, confident, and comfortable (ahn).
