In kung-fu as well as other martial arts styles, you root yourself to the ground on both feet and twist your hips and punch. Say if I’m in a 50/50 stance (50% of weight on one leg and 50% of the other) I can’t feel the root on my legs and feet. I feel that the root is more right down between my legs and feet. Same thing applies to the bow stance and horse stance.
In contrast, in boxing, where you root on one leg only and pivot the other, you can feel the connection to the ground on that one leg.
But in kung-fu with two legs trying to root, you can’t feel the root. It’s more down the center between your legs and feet.
