Eight strange meridians are the general names of Du meridian, Ren meridian, Chong pulse, Dai pulse, Yin meridian, Yang meridian, Yin qiao pulse and Yang qiao pulse. 1. The circulation of Du meridian: ① it starts from the lower abdomen and descends from the perineum, ② it retrogrades in the spine, ③ it goes up to the neck and then enters the brain, ④ it goes up to the top, and ⑤ it goes down to the nasal column along the forehead. 2.

Pulse-taking: ① Starting from the lower part of the costal region, descending obliquely to the acupoints with veins, five axes and Wei Dao, and ② traversing the whole body. 5. Yin-Wei pulse circulation: ① it starts from the inner side of the lower abdomen, ② it goes up to the abdomen along the inner thigh, ③ it meets the Taiyin meridian of the foot, ④ it passes through the chest, and ⑤ it meets Ren pulse at the neck. 6. Yang-Wei pulse circulation: ① it starts from the lateral heel, ② it goes up through the lateral ankle, ③ it goes up through the hip joint along the foot shaoyang, ④ it goes up through the dorsal rib, ⑤ it goes up through the armpit and back shoulder, ⑤ it goes up to the forehead, 7. Yin-webbed pulse circulation: ① starts from the dorsal scaphoid of the foot, ② goes up above the medial malleolus, ③ goes straight along the medial thigh, ④ passes through the vulva, ⑤ goes up along the medial thorax, ⑧ enters the supraclavicular fossa, ⑧ passes through the zygomatic part, ⑨ reaches the medial canthus of the eye, and meets the Sun Meridian of the foot and the Yang-webbed pulse. 8. The circulation of yang collaterals: ① it starts from the lateral heel, ② it goes up to the posterior edge of fibula through the lateral ankle, not through the lateral thigh and the upper shoulder behind the intercostal space, passes through the neck, enters the corner of the eye, meets with the yin collaterals, and then passes through the forehead along the foot sun, ③ it cooperates with the foot with yang deficiency in the wind pool. Ren Du Er mai: It starts from Yin Hui point between the legs just below the human body, and runs from the front of the body along the center to the pith-containing point under the lip. This meridian is ren mai; The Du Meridian, on the other hand, goes backwards along the spine from the point (some say Changqiang point), reaches the top of the head and goes forward between the eyes, reaching the gingival point of the oral maxilla. Ren meridian governs blood and Du meridian governs qi, which is the main meridian of human body. If Ren Du's two veins are connected, then the eight veins are connected; Eight veins are connected with hundreds of veins, which can further enhance physical fitness, strengthen tendons and bones and promote circulation. Ren-Du pulse is very important in TCM pulse diagnosis and Taoist health guidance. At the same time, because there are exaggerated descriptions in martial arts novels, for example, people with high martial arts can get through their own second pulse of Ren Du, and once the second pulse of Ren Du is opened, martial arts will advance by leaps and bounds, so it has become the most familiar name of one pulse.
