Fine Needles also known as small needles (Xiao zhen), are the most widely used in acupuncture treatment, penetrating internal organs and external meridians, with 365 acupoints suitable for various conditions. Historical records state: Qin Yue ren used it to revive Prince Guo from fainting. Hua Tuo used it to stop Emperor Wei’s headache. Zhang Zhongjing treated typhoid with Xiao chai hu (小柴胡) and it was ineffective without needling Qi men (期门). Emperor Gao’s heart disease was not cured until Li Tan used it at Ju que (巨阙). Xu Wenbo needled He gu and San yin jiao to diagnose the twin pregnancy of the Song prince. Zhen Quan needled Jian jing (肩井) and Qu chi (曲池) to stop arm pain and restore function. Qiu fu needled Yao yu (腰俞) to relieve chronic illness. Wang Zuan needled at the intersection to drive away evil spirits. Needling Gan yu (肝俞) and Ming men (命门) can restore sight to the blind. Needle Shao yang (少阳) and Jiao bie (交别) to help the deaf hear the sound of summer insects. These are miraculous achievements of the predecessors, left for future generations to reference and continue to develop. Building on the achievements of predecessors, through repeated exploration and research, combined with clinical practice, new experiences have been created, such as using the five organ points and diaphragm point to treat deficiencies and labor injuries while also addressing menstrual issues. The three points: Qi hai (气海), Zhang men (章门), Tian shun (天枢), Nei guan (内关), and Zu san li (足三里) can strengthen the spleen and harmonize gastrointestinal function. Tian tu (天突) and Dan zhong (膻中) can descend phlegm, stabilize asthma, and open the chest to smooth qi. Da zhui (大椎) and Shen zhu (身柱) treat epilepsy in adults and children. For wind in the meridians: effective points include Bai hui, Feng fu (风府), Qu chi, He gu, Nei guan, Zu san li, Yang ling quan (阳陵泉), and San yin jiao. For wind in the organs: needle Lian quan (廉泉), Tian tu, Ju que, Zhong wan (中脘), Xia wan (下脘), Qi hai, Guan yuan (关元), Zhong ji (中极), Tian shun, and Zhang men for light treatment. Zhong wan and Zu san li have effects similar to those of stomach tonics and harmonizers. Tian shun and Qi hai have effects similar to those of kidney tonics. Da zhui and Nei guan correspond with Zhang Zhongjing’s Qing long ling gui decoction. Yu ji (鱼际) and Tai xi (太溪) are similar to the method of clearing dryness to rescue the lungs. Zu san li and the upper and lower Ju xu (巨虚) have effects similar to those of the Golden Cabinet’s major and minor purging formulas. Yin bai (隐白), Da du (大都), and Tai bai (太白) correspond with Dong yuan’s method of tonifying the middle and regulating the center. Zu san li can be compared to Bu zhong yi qi (补中益气). San yin jiao contends for merit with Ba zhen (八珍) and kidney qi. Zhang men, Zu san li, Nei guan, and Zhong wan are similar to the symptoms treated by Shen, Shu, Ling, and Si jun zi (四君子). San yin jiao, Qu chi, Tai chong (太冲), and Guan yuan have effects similar to those of Gui, Xiong, and Shao (四物). He gu connects with Wei qi, similar to Huang qi’s effects in stopping sweating and inducing sweating. Yang ling quan moves the blood and is similar to Rou gui’s effects in relieving stiffness and relaxing the muscles. The above ten points roughly correspond to the effects of the Ten Complete Great Tonics, merely representing my initial observations and creations, hoping for corrections and further exploration from my peers.3.

Large Needles refer to fire needles (Huo zhen), also known as burning needles. They are primarily used in internal medicine, often needling at acupoints, for example, for hard-to-dissolve masses, cold diseases, or wind-cold invading the stomach, which can lead to cold obstruction, pain, and water-fire imbalance, resulting in edema that cannot pass through joints, or wind-cold causing muscle spasms and pain, numbness, etc. The needle should be slowly withdrawn while rotating to expel impurities. In surgery, they are often used at the affected area, for example, for abscesses, carbuncles, scrofula, and unnamed swellings, or in thick flesh areas that have already formed pus, the needle should be used to allow the pus to drain without pressing on the needle hole. There is also a type of fire needle shaped like a nail cap, used to treat liver deficiency causing blurred vision, wind-heat generating membranes, stubborn tears, or virtual labor rising, causing membranes to form in the eyes leading to blindness. A flat-headed needle is heated red and then pressed against the membrane to burn it, after which the membrane breaks, and a medicinal ointment is applied to help the eye recover. Fire needles are contraindicated for conditions on the head and face, during summer, for those with damp-heat descending to the legs, and for febrile diseases.
