Small problem here. “Kung fu” (功夫) doesn’t mean what you seem to think it means. It doesn’t mean “martial arts”. It is applicable to any skill that takes dedication and practice, so applies equally to things like making tea, musical performance, or even gardening.

Which kind of makes the rest of that site risible since there is no “Crane Style” of tea-making, no “Tiger Style” of gardening, etc.
