In 1990s the endless legal and libel battle began among three men - Kim Jeong-ho and Na Han-il, the founder of handing gumdo, and Kim Chang-sik of "Shim Gum Do". Meanwhile, the history and truth of haidong gumdo, which were hidden, were coming out gradually.
After all, the court of Korea revealed the history of haidong gumdo. Let us see its history appeared in court step by step.

Q: Does the deponent(Na Han-il) know the fact which the word of "haidong gumdo" used in 1982 for the first time?
A: Yes.

Q: Who invented this name?
A: Choe Tae-min, the priest invented it. He is a third person.

Q: Did the deponent close your "Shim Gum Do" gymnasium when you ran it with Kim Jeong-ho in 1983?
A: I just replaced a nameboard, and continued to run it.

Q: Does the deponent(Na Han-il) understand that "Shim Gum Do" and handing gumdo differ in content?
A: They don't differ but have relevance to each other.

Kim Chang-sik, the founder of "Shim Gum Do", also claims "Shim Gum Do" is not haidong gumdo. Kim Chang-sik clarified the reasons why he sought a provisional injunction in the application form to prohibit the release　and distribution of the books and others. He wrote "'Shim Gum Do' has the characteristic to manipulate sword in one hand. In the others' sword two hands are used". Now in haidong gumdo, the method of two hands is mainstream, Unlike 'Shim Gum Do'.
When our magazine interviewed Kim Chang-sik, he surely confessed that he taught Na Han-il and Kim Jeong-ho directory. Then he also explained why "Shim Gum Do" and haidong gumdo differ, and the founders of haidong gumdo have never gone to "Ki Chun Moon" when they learn "Ki Chun Moon". The facts are simple.

Kim Jeong-ho, the president have learned Ki Chun Moon, and it is no wonder that he changed the narrative of Ki Chun Moon to the narrative of haidong gumdo. Still, some of the people, who learned Ki Chun Moon, have once met to learn discipline in the small house at Mt. Gwanak. This clarifies the rationale for Kim Jeong-ho's claim that master Baek Du-san taught him haidong gumdo at Mt.Gwanak.

In the result, master Baek Du-san was Pak Dae-yang of Ki Chun Moon.
And according to the evidence of Kim Chang-sik, who is the founder of Shim Gum Do, Mr. Son created Pungcha geombeop(風車剣法), giving the 100 days' invocation at Mt.Gwanak where the founders of haidong gumdo also learned this sword. Such various facts formed the basis to giving a concrete shape to master Baek Du-san, a fictional character, who taught haidong gumdo at Mt.Gwanak. It seemed Kim Jeong-ho's idea that Pak Dae-yang and Son promoted to master Baek Du-san.
