Guiding techniques, which originally came from the "Inner Canon of Huangdi," were meant to treat tendon diseases and symptoms of heaviness in the limbs. Over time, they were gradually incorporated into mainstream medicine and medical qigong. It was not until the emergence of the Eight Pieces of Brocade that guiding techniques truly began to flourish, proving to be quite effective in medicine, health preservation, and physical exercise.
Martial arts, especially Internal Fist, are also involved in health preservation and physical training, such as Xingyi's Bone and Muscle Strengthening. So when Wu started his Bone and Muscle Strengthening, he researched the Eight Pieces of Brocade. Seeing Xu Ming execute this set of movements, the first half of which included Tai Chi postures and some elements of the Eight Pieces of Brocade, piqued Wu's interest.
