The Ren and Du Chakras are two different meridians, the Ren and the Du Chakras. The Directing Vessel is the sea of yang chakra, which regulates the yang meridians and qi of the whole body. The Ren is the sea of yin veins and regulates the yin meridians and qi of the whole body. The Directing Vessel starts at the lower end of the spine and ends at the face, mainly traveling in the back of the waist and back of the center line and the head, with acupuncture points including lumbar yangguan, vital gate, zhi yang, Baihui, shenting, shui gou, and daxi vertebrae. The Directing Vessel governs all yangs, and can be used to treat psychosomatic diseases, fever, and lumbosacral disorders. The Ren Vessel starts from the middle line of the abdomen and ends at the lower jaw. It mainly circulates in the front center line of the body, and it can take over the whole body’s yin meridians and qi, so it is the sea of yin meridians. The acupoints of the Ren vein can treat localized diseases of the chest, abdomen, head and face, as well as diseases of the internal organs, and some of the acupoints have a strong effect, such as Guanyuan and Qihai. The Ren and Dudu veins are part of the eight meridians of the human body, and by stimulating the acupoints along their routes, they can be used to treat diseases. If there is a need for treatment, it is recommended that acupuncture be performed under the guidance of a professional physician, not blindly.
