Xingyiquan Pi Quan | Detailed Explanation Part Three 

To develop the elastic body, you have to fix the feet. Knees should not be fixed. The whole body twist.

Thanks a lot. I was missing this. My legs moved after my body, compensating and interfering with the development of body elasticity. Your video helped me understand this. We'll have to go back to the beginning and, having fixed the lower body, go through a better path of development. Thank you for this term "elastic force" He helped me understand the difference between shenfa based on structure and shenfa that emphasizes the connection between dantian and consciousness. Does this mean that in santishi the lower body, due to the compression of the kua, is strictly directed with the dantian forward, and the upper body tries to twist as much as possible, pushing the shoulder and leading arm forward, fixing this twisted position for the entire time of standing?

You’re welcome! Yes, you have to compress toward the center. Regarding twisting, don’t over twist.

Thank you. It became much clearer. Rely more on the Dan Tien movement than on the rotation of the lower back.
