Go to any forum on kung fu or martial arts and you are going to read the, “What is the difference between kung fu and gung fu?” The answer is…nothing. This is like saying what is the difference between pop and soda? The difference is dialect and what part of the country your are from. Kung fu comes from the Mandarin dialect; which is prominent in Northern China. Gung fu is Cantonese from Southern China. Both are translated to the same thing; “hard work” or “effort.”
Don’t let little things like dialect distract you from the true reason you train a martial art, because you like it.
