 In the 1990s, karate instructor George Dillman developed a style that involves "kyūshojutsu", a term that he identifies with "dim mak".Dillman eventually went as far as claiming to have developed "qi"-based attacks that work without physical contact ("no-touch knockout" techniques), a claim that did not stand up to third-party investigation and was consequently denounced as fraudulent.A "Five Point Palm Exploding Heart Technique" appears in both the Shaw Brothers films "Clan of the White Lotus" (1980) and "Executioners of Shaolin" (1977).
