Abstract：Professor ZHONG Weiquan believes that the pathogenesis of chronic insomnia involves disharmony of yin and yang，qi and blood，and zang-fu organs. Treatment can be enhanced through multi-technique synergy：first， the Renying-Cunkou pulse diagnosis method is used to determine the syndrome and guide yin-yang supplementation or drainage； then， the Qihuang acupuncture technique is applied to back-shu points to regulate the zang-fu organs； finally， filiform needles are used to drain the Baxie （EX-UE9） points to unblock qi and blood circulation， reduce excessive yang， and enable yang to enter yin. Based on this approach， the treatment of chronic insomnia is wellstructured， with clinically favorable outcomes.
