So, an interesting tidbit of information: did you know that in the traditional Shaolin bow, the hands form the character which means "Bright" and refers to the Ming dynasty? The closed hand represents the character for "sun" and the open hand represents the "moon" which collectively mean "bright" or Ming. One who makes this sign signifies that he (1) calls for the return of the Ming dynasty and (2) is himself "bright", as in being an agent of justice (the light side, if you will).
