Abstract： This paper summarizes and introduces Professor LONG Xiangyu's clinical experience in treating postpartum low back pain with tendon-soothing tuina therapy. Professor LONG believes that postpartum low back pain falls within the category of spine-related disorders and proposes that the core pathogenesis is qi deficiency and blood stasis combined with liver and kidney deficiency. Accordingly， he establishes the treatment principle of "restore the balance of tendons and bones， giving priority to regulating the tendons" and the therapeutic method of "tonifying the liver and kidney， nourishing qi and blood， and activating qi and unblocking meridians." Professor LONG Xiangyu's self-made "Jianxiang Tendon-Soothing Tuina" manipulation has achieved certain clinical outcomes in treating postpartum low back pain.
