Tang Soo Do tradition has always held that Grandmaster Hwang Kee, founder of the Moo Duk Kwan, brought these forms to Korea from China where he had studied in his youth. Most Tang Soo Do Masters will tell you, "Hwang Kee bring Pyong Ahn Hyung back from China, " The Grandmaster' s son himself, Hwang Hyun Chul, Director of the United States Tang Soo Do Moo Duk Kwan Federation (Springfield, NJ), has stated, "My father bring the forms back from China."
As much as any of these masters may wish to convince you of this fact, they should not...because it is not true. The Pyong Ahn forms are not Chinese...they're Okinawan in origin. The fact that this is common knowledge to students of Japanese and Okinawan Karate had led to a good number of insults and more than one rumor that Hwang Kee had traveled to Japan or Okinawa and studied the forms. One myth even claim's Hwang Kee spent a few months on Okinawa studying Shorin-ryu and Goju-ryu Karate. Another states that the Pyong Ahn series were created by both Hwang Kee and Funakoshi Ginchen (the founder of Shoto Kan Karate).
The story goes 'Funakoshi and Hwang traveled to China where they studied Chinese martial arts. Together, they created the Pyong Ahn forms. Each then returned to his respective country and began teaching his own version'. Stories such as this bring mild amusement in their most benign form, and do a great deal of damage to the credibility of Tang Soo Do masters at their worst. A simple check of facts can quickly show how great a fallacy the story is.
While Hwang Kee did travel to China, there is no evidence he and Funakoshi were traveling companions. This is easily denounced by the fact Funakoshi never traveled to China. He was an Okinawan who relocated to Japan where he lived out his life. Lastly, Hwang and Funakoshi were not contemporaries in the sense the story implies. Funakoshi was born in 1868. In 1927, he relocated to Japan where he remained until his death in 1957 (Funakoshi, 1975). Hwang Kee was born in 1914 just north of Seoul, Korea. In 1935, following completion of High School, Hwang traveled to China as part of his job, and remained until 1937 (Hwang, 1995). If you do the math you will see that Funakoshi was 46 years old when Hwang was born. By the time Hwang left for China, Funakoshi was 67 years old, while Hwang was only 21. Unless the Japanese Empire regularly sent senior citizens into hostile occupied areas, it isn't at all likely Hwang and Funakoshi even ever shared the same train. Comtemporaries...not!
Nonetheless, some rumors have perpetuated that Hwang Kee studied from Funakoshi at the Shoto-Kan. However, no evidence has ever surfaced that Hwang and Funakoshi ever trained together, nor even ever met one another. Pyong Ahn is the Korean pronunciation for the Chinese characters associated with this series.The forms were first created in 1901 by Itosu Yasutsune, a Shorin-ryu Karate master on Okinawa. The Okinawan dialect pronounces these characters 'Pin An'.
The study of Karate was still a secret practice during Itosu's early life. Dojo (martial art schools) were no more than small groups of initiates who carried out their practice discretely and in private. The training was typically brutal and the curriculum focused on forms training and its application in prearranged sparring sequences . Itosu himself was a school teacher and he recognized in Karate a method by which Okinawan youth could strengthen their bodies while building good characters. Itosu, however, did not believe that young people should be taught the secrets of Karate with its potentially fatal uses until they had successfully proven themselves. Therefore, he set out to create a style of Karate that could be easily instructed and learned. His brainchildren were the Pinan Kata which were created by combination of two older forms, Kushanku (Korean: Kong Sang Koon) and Chiang Nan (Korean: Jae Nam) (or, at least, that is the oral his tory) .
A total of five forms were created and introduced into the Okinawan public schools as instruction for children at the elementary school level. From 1905 to 1909, one form was introduced each year. Itosu, in time, would teach his art to another Okinawan, Funakoshi Ginchen, who eventually would prove to be a significant figure in the migration and modernization of Karate. Funakoshi was destined to travel to Japan and teach a version of the Pinan forms and to eventually rename them Heian. Other former students of Itosu, such as Mabuni Kenwa (founder of Shi to- ryu ) , would also relocate to Japan and teach versions of the Pinan Kata. This series eventually would make its way into Korea through Koreans who studied in Japan, such as Lee Won Kuk (Chung Do Kwan), Choi Hong Hi (Oh Do Kwan), Yoon Byung In (Chang Moo Kwan), and Ho Byung Jik (Song Moo Kwan).
In 1978, Hwang Kee published Tang Soo Do (Soo Bahk Do). On page 372 of this book, Hwang elaborates on the Pyong Ahn Hyung as follows:
Originally, this form was called 'Jae Nam' Approximately 100 years ago an Okinawan Master, Mr. Idos, reorganized the Jae Nam form into a form closely resembling the present Pyong Ahn forms...
In his latest book, The History of Moo Duk Kwan (1995), which is available through the United States Soo Bahk Do Moo Duk Kwan Federation, Hwang Kee states on pages 15 and 16 that his knowledge and understanding of the majority of forms taught within Tang Soo Do, including the Pyong Ahn Hyung, came through reading and studying Japanese books on Okinawan Karate. Hwang discovered these books in the Library of the train station in Seoul where he worked in 1939 (Hwang, 1995). We can only speculate as to which books these were, but it is known that Funakoshi and others published books on Karate as far back as 1922.
While the above information was withheld for 50 years, the clue could always be found within the forms themselves. It has been known for many years that the Karate-Ka in Japan switched the order of the first two forms from their original. Hence, anyone who trains in a traditional Okinawan school have the original order, while those that trace lineage through a Japanese school have Pinan No. 2 as their version of Pinan No. 1, and vice versa. Tang Soo Do practitioners need to take note here as their order is the same as used by the Japanese schools.
