According to Taoism, the Yellow Sutra refers to the center of the human body, which is also called the Yellow Sutra, the Middle Path, the Zodiac, the Yellow Sutra, the Yellow Vein, the True Yellow and the True. That is, the midvein in Tibetan Buddhism. Midrib is the most important pulse of Zhuoding Fire. This pulse is invisible and has no phase, and it runs up and down with qi, and runs on Sunday. As long as Zhuo's true qi and shining point can get through the five chakras, he can achieve immortality in this life.
