春夏致一阴，用针深坑入皮五分，至肾肝之部，致阴气以和阴，浮入皮二分，至心肺之得气引持。
秋冬致一阳，用针浅，气以和，阴部得气，推内致阳。当补，从卫取气，得气推纳。当泻，从荣买气，得气引泻。
阳不足，阴有余，当先补阳而后泻阴。假令胆不足、肝有余，先补足少阳胆经，然后泻
大指出是补，呵是暖；大指入是泻，吸是凉。
急提慢按，自然凉泻；慢提急按，自然热补。
一飞二进，真气自至；一退三飞，邪气自微。
泻，气来实而牢牢实者，泻之；补，气来虚而濡者，补之。
疼痛即泻，先吸后呼之；痒麻即补，先呼后吸之。
凡补泻，先诊五脏脉，及用刺之穴。
未欲行针，先审晦晴，察其病源，论定何经络，已定穴窍分明，五行生克补泻于心。血
支血忌，莫犯人神，太乙在宫，切莫施针。寒热醉饱，劳弱风阴。春夏宜暖，秋冬大温。端心正
已，如待贵宾。左手按定，右手持针。秋冬三五二四，春夏气候已至。补阳泻阴，泻阳先呼
，泻阴吸存。循扪有穴，何病之因，疼痛已愈，随除起针。患者病未，补阴重分。合穴相引
，何患厥深。行针之士，当熟在心。先贤贵言，宝之如金，誓若漏言，祖考受刑。
《针微赋》说∶下针如龙投大海，起针似猛虎离山。针有劫病之功，药有拔山之力。江
河闭塞， 锄开之；气血凝滞，须用砭针刺之。针头如粟米，气出似云烟。
《黄帝内经》云∶人身有三百四十九道，单穴四十九道，双穴三百一十。
《铜人经》云∶六百四十四穴，所处不同。识得阴阳，辨得虚实，知其逆顺，是动所生
，方可行针。虚则补之，实则泻之，不虚不实，根据经取之。针之毫毛，隐显莫测，下针必在灵
验。一呼一吸，如江河滚滚而来；一按一提，似角弓展展而开。针之玄妙，至理难通。上察
周天缠度，奋然气引而来，下极黎庶残骸，却邪陶陶而去。针有孔穴，按天地人三才，涌泉
与璇玑、百会。把攒五岳，恒衡岱华嵩。人有五脏，心肝脾肺肾。针有五穴，井荥输经合。
沟渠闭塞，水在于内，经络不通，气血在中。开渠流水，引气而行。亘古至今，补虚泻实，
宜浅宜深。然虽手到处，人心巧巧，名传四海。虽不针枯骨重活，自然有起死回生。
览此斯言，神明佑之。
春夏季节要引导阴气，进针要深，刺入皮肤五分，到达肾和肝所在的部位，以引致阴气来调和阴分；然后浅提至皮下二分处，到达心肺所在之处，待得气后持针不动。
秋冬季节要引导阳气，进针宜浅，使气机调和，在阴部得气后，将针推入以引致阳气。应当补法时，从卫分取气，得气后将针向内推进；应当泻法时，从营分取气，得气后将针向外引拔。
阳气不足、阴气有余时，应当先补阳而后泻阴。例如胆气不足、肝气有余，先补足少阳胆经，然后再泻之。
大指向前捻转是补法，呵气（呼气）感觉温暖；大指向后捻转是泻法，吸气感觉清凉。
快速提针、缓慢按针，自然产生凉感以行泻法；缓慢提针、快速按针，自然产生热感以行补法。
一进针如飞一次，退针三次如飞，真气自然会到来；退针一次，进针如飞三次，邪气自然会减弱。
泻法：当针下感觉充实而坚实有力时，施行泻法；补法：当针下感觉虚弱而濡软时，施行补法。
疼痛症状即施泻法，操作顺序为先吸气后呼气；痒麻症状即施补法，操作顺序为先呼气后吸气。
凡是进行补泻操作，必须先诊察五脏的脉象，以及确定使用的针刺穴位。
尚未开始行针前，先观察天气阴晴，考察疾病的根源，论述清楚是哪条经络病变，已经确定的穴位要分明，心中要有五行生克补泻的道理。避开血支、血忌之日，不要触犯人神禁忌，太乙所在宫位时，切勿施针。寒热病、醉酒、饱食、劳累、体弱、风邪、阴证等情况需慎重。春夏季节适宜温和，秋冬季节尤其需要温补。端正心态，正己修身，对待患者如同等待贵宾一样恭敬。左手按压固定穴位，右手持针操作。秋冬季节进针深度为三寸或五寸、二寸或四寸（注：原文“三五二四”指代深浅或次数，此处依语境译为深浅或操作节奏），春夏季节顺应气候特点。补阳泻阴时，泻阳先让患者呼气，泻阴时让患者吸气留存。循按寻找穴位，明确病因，疼痛已愈，随即起针。如果患者病势未减，补阴时要分层操作。合穴相互牵引，何愁厥逆之症深沉。行针的医师，应当熟记于心。先贤宝贵的言论，应像金子一样珍视，发誓若泄露此秘，祖先将受刑罚。
《针微赋》说：下针如同龙投入大海，起针好似猛虎离开山峦。针刺有劫除病邪的功效，药物有拔起重物的力量。江河堵塞，用锄头疏通；气血凝滞，必须用砭石或针刺破它。针头细小如粟米，出气飘逸似云烟。
《黄帝内经》说：人身有三百四十九个穴位，单穴四十九个，双穴三百一十个。
《铜人经》说：共有六百四十四穴，位置各不相同。认识阴阳，辨别虚实，知道逆顺规律，了解经气变动所生的病症，才可以行针。虚证用补法，实证用泻法，不虚不实者，根据经脉理论选取穴位。针具细微如毫毛，隐显变化莫测，下针必须灵验有效。一呼一吸之间，气机如江河滚滚而来；一按一提之间，力道似角弓缓缓张开。针刺的玄妙之处，深奥的道理难以完全通晓。上观察周天度数，振奋地引导气机到来，下关怀百姓身体，驱除邪气使其陶然离去。针刺有关孔穴，对应天地人三才，如涌泉、璇玑、百会等穴。汇聚如五岳（恒山、衡山、泰山、华山、嵩山），人有五脏（心、肝、脾、肺、肾）。针刺有五类特定穴（井、荥、输、经、合）。沟渠堵塞，水积在内；经络不通，气血停滞其中。开通沟渠让水流淌，引导气机运行。从古至今，补虚泻实的原则，宜浅则浅，宜深则深。虽然手到之处，人心巧妙，名声传遍四海。虽然不能使枯骨重新复活，但自然有起死回生的功效。
阅览这些言语，神明会保佑你。
In spring and summer, to draw in Yin, insert the needle deeply into the skin by five fen, reaching the regions of the Kidney and Liver, to induce Yin Qi to harmonize the Yin aspect; then withdraw superficially to two fen below the skin, reaching the areas of the Heart and Lung, wait for Deqi (arrival of needle sensation), and hold the needle steady.
In autumn and winter, to draw in Yang, insert the needle shallowly to harmonize the Qi; upon obtaining Deqi in the Yin region, push the needle inward to induce Yang Qi. When tonification is indicated, take Qi from the Wei (Defensive) level, and upon Deqi, push the needle inward. When sedation is indicated, take Qi from the Ying (Nutritive) level, and upon Deqi, pull the needle outward.
When Yang is deficient and Yin is excessive, one should first tonify Yang and then sedate Yin. For example, if Gallbladder Qi is deficient and Liver Qi is excessive, first tonify the Shaoyang Gallbladder Meridian, and then sedate it.
Rotating the thumb forward constitutes tonification, accompanied by exhalation creating a warm sensation; rotating the thumb backward constitutes sedation, accompanied by inhalation creating a cool sensation.
Rapid lifting and slow pressing naturally produces a cool sensation for sedation; slow lifting and rapid pressing naturally produces a thermal sensation for tonification.
One flight forward (insertion) brings True Qi naturally; one retreat backward with three flights forward (insertion) causes Evil Qi to diminish naturally.
For sedation: when the needle sensation feels solid and firm, apply sedation. For tonification: when the needle sensation feels empty and soft, apply tonification.
For pain symptoms, apply sedation using the sequence of inhaling first then exhaling; for itching or numbness symptoms, apply tonification using the sequence of exhaling first then inhaling.
Generally, before performing tonification or sedation, diagnose the pulses of the Five Zang Organs and determine the acupoints to be used.
Before initiating needling, observe the weather conditions, investigate the source of the disease, identify the affected meridians, ensure the acupoints are clearly defined, and keep the principles of Five Elements generation/inter-restriction and tonification/sedation in mind. Avoid days of Blood Branch and Blood Taboo, do not offend the Ren Shen (Human Spirit), and do not needle when Tai Yi is in the palace. Be cautious with cold-heat disorders, drunkenness, fullness, fatigue, weakness, wind pathogens, and Yin syndromes. Spring and summer suit warmth; autumn and winter require significant warming. Maintain a centered mind and correct demeanor, treating patients as if awaiting distinguished guests. The left hand presses and fixes the point, while the right hand holds the needle. In autumn and winter, depths may vary (three-five, two-four); in spring and summer, follow the climate characteristics. To tonify Yang and sedate Yin, when sedating Yang, have the patient exhale first; when sedating Yin, have the patient retain their breath after inhalation. Palpate and press to find acupoints, understand the cause of the disease, and remove the needle once pain is relieved. If the patient's condition persists, tonify Yin in layers. He Gu points guide each other, alleviating deep Jue (cold extremities). Practitioners must memorize these principles. The words of sages are precious as gold; swear that if leaked, ancestors will suffer punishment.
The *Zhen Wei Fu* states: Inserting the needle is like a dragon diving into the sea; withdrawing it is like a fierce tiger leaving the mountain. Needling has the merit of劫病 (snatching away disease); medicine has the strength to move mountains. If rivers and lakes are blocked, use a hoe to clear them; if Qi and Blood are stagnant, use Bian stones or needles to pierce them. The needle head is small as millet grains, and the Qi flows out like clouds and smoke.
The *Huangdi Neijing* says: The human body has 349 acupoints, including 49 single points and 310 paired points.
The *Tongren Jing* says: There are 644 acupoints, located differently. Recognizing Yin and Yang, distinguishing deficiency and excess, knowing reversal and smoothness, and understanding the changes generated by meridian Qi allows for needling. Tonify deficiency, sedate excess, and for neither deficient nor excess conditions, select points according to the meridians. The needle is fine as hair, its effects hidden and unpredictable; needling must be effective. With each breath, Qi arrives like rolling rivers; with each press and lift, force opens like an unfolding crossbow. The mystery of needling is profound and difficult to fully comprehend. Observe the celestial cycles above, vigorously guiding Qi to arrive; care for the common people below, driving away Evil Qi joyfully. Acupoints correspond to Heaven, Earth, and Humanity (San Cai), such as Yongquan (KI1), Xuanji (CV15), and Baihui (GV20). Gather the Five Great Mountains (Heng, Heng, Tai, Hua, Song). Humans have Five Zang Organs: Heart, Liver, Spleen, Lung, Kidney. Needling utilizes Five Shu Points: Jing-Well, Ying-Spring, Shu-Stream, Jing-River, He-Sea. If ditches are blocked, water stays inside; if meridians are obstructed, Qi and Blood stagnate within. Open the ditches to let water flow, guiding Qi to move. From ancient times to now, tonifying deficiency and sedating excess, shallowing or deepening as appropriate. Though hands act skillfully, fame spreads across the four seas. Though one cannot revive dead bones, there is naturally the power to bring the dying back to life.
Reviewing these words, divine spirits will bless you.
