Abstract：Low back pain involves a wide range of diseases and has complex disease locations. ZHANG Zhongjing advocated in his book Shang Han Za Bing Lun (Treatise on Cold Damage and Miscellaneous Diseases) that all six meridians have manifestations， including low back pain. Low back pain involves the pathogenesis of the three yin manifestations， which is mainly about the stagnation of yin and cold in muscles， fascia， and joints， and the main treatment method is warming yang and dispersing cold. According to the location of the disease，it can be classified into four categories and four methods：in the treatment of Taiyin，warming the spleen and dispelling cold，and resolving dampness and relieving pain；in the treatment of Shaoyin，warming the kidney and dispelling cold，and resolving dampness and unblocking meridians； in the treatment of Jueyin， warming the liver and nourishing blood， and warming meridians and unblocking collaterals； and in the treatment of multiple meridians， promoting yang and diffusing impediments，and dispelling cold and resolving dampness.
