Just wondering where qi came from and why the amount of games you play were called "qi". I always thought it was iq backwards but I'm just wondering about the legitimate reason

probably its QI because the ammount of games you play you can get better(high belts don't mean high skill) because of experience you got playing,you increase you experience.

i.q.: Intelligence quotient,maybe they putted it backward to others don't think QI is the same as i.q .

take a look at this page on wikipedia.

Pretty sure it has to do with Ki
