Bi syndrome is classified into five categories. Based on the syndrome differentiation of meridians and collaterals and zangfu theories, Professor WU Zhongchao proposed the fire needling therapy at the lower he-sea points for five types of bi syndromes. Professor WU stresses on the flexible application of fire needling therapy for bi syndrome at the lower he-sea points and innovated the unique five techniques of fire needling therapy, named lifting and threating needle of small amplitude at the lower he-sea points, the stimulation along the relevant meri-dians before fire needling, detecting the sensitive sites by gentle pressing the relevant lower he-sea points, combining the movement of affected upper limb or joint during fire needling, or combining with contralateral needling technique, and controlling the depth of fire needling based on the duration of sickness and depth of affected site. He pointed out that Shangjuxu (ST 37) is for skin bi syndrome, Zusanli (ST 36) for muscle bi syndrome, Yanglingquan (GB 34) for tendon bi syndrome, Weizhong (BL 40) for bone bi syndrome and Xiajuxu (ST 39) for vessel bi syndrome.
