Abstract：This paper introduces the clinical experience of MO Xiaofeng in the treatment of Hashimoto thyroiditis at hypothyroidism stage from the perspective of qi. Based on HUANG Yuanyu's theory of circulation of qi movement in body，MO Xiaofeng believes that the pathogenesis of Hashimoto thyroiditis should be attributed to emotional factors. As the disease develops into the hypothyroidism stage，the liver qi is stagnated for a long time， spleen earth in the middle energizer is deeply effected， qi movement is depressed and stagnated，and the normal movements of qi，blood and body fluid are impeded. Therefore， the treatment should be based on the perspective of qi in clinical practice. The liver-soothing three needles of QI's umbilical needle should be given as the main treatment，and the middle-qi-upraising three needles or yin-nourishing three needles can also be applied accordingly；combining the concept of hole and layer in JIN's acupuncture theory， local shallow encircling needling is also given to activate the normal blood and fluid transportation， and the purposes of curing the disease and guarding against pathogens can be achieved.
