What is the difference between "internal strength" and "mental method" in traditional Wushu?

In fact, my friend's internal strength consists of two parts, one is Wushu Qigong, and the other is Wushu internal strength. Together, these two parts are a complete internal skill, but no matter which one is practiced, it can be called internal qigong. Internal strength is to improve the strength and penetration of kung fu, adjust one's internal organs system, make the kinetic energy of physical strength flow completely, and send out strength through reasonable skeletal guidance posture. I have made it very clear.

Mind method is the practical experience of predecessors, my friend.
