The spirit of a weak person is bright; Top strength, gently pull up the inner strength, and let Yang Qingzhi rise; Sinking aura means that human energy is hidden in the field list during exercise. The specific methods are as follows: take back your chin to find your throat, and the throat will look for the jade pillow backwards and upwards, and the jade pillow will look for Baihui upwards, and Baihui will be suspended, so that the whole body will be connected into a whole. "thirteen potential exercises" says: "if the spirit can bear it, there is no fear of delay, so-called head hanging." Head hanging should focus on the word "hanging", starting with the word "top". "Hanging" refers to the virtual collar, which belongs to softness, and "top" refers to the slight contraction of the rectus cervicalis, which belongs to rigidity, and it should be combined with rigidity and softness everywhere. The top strength of virtual spirit is by no means hard top, hard top is hard strength, not real top strength. Try not to push your neck too hard. If the neck is forced too hard, the healthy qi will rush to the head, and the blood pressure will rise, the head will be heavy, the feet will be unstable, the torsion will be ineffective, the pulse will be blocked, and the chest will be full of gas, which is harmful to the body. You can't be too strong. If you don't do this, you will be listless and prone to other ideas. Therefore, the theory of Taiji Zhuan points out: "If qi is lifted, if it is intentional, if it is unintentional, it is neither light nor heavy. There seems to be something, nothing is nothing, that is, a discount. "
