乘车前来就诊的患者，让其躺下休息约一顿饭的时间，然后再进行针刺；步行前来就诊的患者，让其坐下休息相当于行走十里路所需的时间，然后再进行针刺。
如果因大惊大怒而误刺，患者五日后会死亡，其表现为呵欠；如果误刺脾脏，十五日后会死亡，其表现为吞咽动作异常；如果误刺肾脏，三日后会死亡，其表现为打喷嚏；如果误刺胆腑，一日半后会死亡，其表现为呕吐；如果误刺膈肌，会损伤中气，不超过一年必定死亡；如果误刺足背的大脉，出血不止会导致死亡，所谓“趺上大脉”，即动脉；如果误刺大腿内侧的大脉，出血不止会导致死亡；如果误刺面部流动之脉，会导致无辜失明（此处指非眼部病变导致的失明）；如果误刺头维穴且进针过深伤及脉络，会导致内部漏泄并耳聋；如果误刺项部脑户穴，针入脑部立即死亡；如果误刺膝盖髌骨处导致关节液流出，会导致跛行；如果误刺舌下大脉且出血不止，会导致失音；如果误刺手太阴肺经的经脉，出血过多会立即死亡，手太阴经的经渠穴不可出血，一旦出血立即死亡。按语：此处的臂部太阴脉总归是不能出血的；如果误刺足底分布的络脉中的血管，血液不出会导致肿胀，所谓的“布络”是足少阴肾经皮部的络脉；如果误刺足少阴肾经且患者本就虚损又见出血，会导致舌头僵硬难以言语，因为足少阴肾经连系到舌根，如果脉象先已虚弱再被刺出血，就称为双重虚损，所以导致言语困难；如果误刺腹部大脉，使人跌倒、面色苍白，针刺诸处穴位时应当避开空处直接刺入，不可刺中大络；如果误刺胸中且进针过深伤及肺脏，会导致气喘逆乱、仰卧呼吸，此穴又名中府，是肺的募穴；如果误刺腹股沟中的脉管，血液不出会导致鼠鼷部位肿胀。
如果误刺肘中且进针过深使气陷入其中，会导致手臂不能屈伸；如果误刺脊柱间隙伤及脊髓，会导致驼背；如果误刺大腿内侧下方三寸处且进针过深，会导致遗尿。

Sun Simiao stated: The medical classics record: "Needling Yunmen (Cloud Gate, LU-2) must not be deep." Currently, it is strictly taboo to needle this point; students of acupuncture should be thoroughly familiar with this.
One must not needle during extreme cold; one must not apply the reducing method when the moon is waxing; one must not apply the reinforcing method when the moon is full; one should not treat when the moon's light is waning and empty; one must not needle immediately after sexual intercourse; one must not engage in sexual intercourse immediately after needling; one must not needle when extremely angry; one must not become angry immediately after needling. One must not needle when hungry.
For patients who arrived by carriage, let them lie down and rest for the time it takes to finish a meal before needling; for patients who arrived on foot, let them sit and rest for the time equivalent to walking ten *li* before needling.

Commentary: The Taiyin vessels of the arm generally must not bleed; if the network vessels distributed under the sole are accidentally punctured and blood does not come out, swelling occurs; "Buluo" refers to the network vessels of the skin portion of the Foot Shaoyin Kidney Meridian; if the Foot Shaoyin Kidney Meridian is needled in a patient with pre-existing deficiency and bleeding occurs, it results in double deficiency, causing difficulty in speech, because the Foot Shaoyin Meridian connects to the root of the tongue; if the large vessel in the abdomen is accidentally punctured, the person falls and loses color; when needling various points, one should avoid empty spaces and not strike the large collaterals; if the chest is needled too deeply injuring the lung, panting, counterflow breathing, and orthopnea result; this point is also known as Zhongfu (LU-1), the Front-Mu point of the Lung; if the vessel in the groin area is accidentally punctured and blood does not come out, swelling of the inguinal region (rat groin) occurs.
If Qi enters deeply into the elbow due to accidental needling, flexion and extension of the limb become impossible; if the spinal marrow is accidentally punctured between the vertebrae, kyphosis results; if the area three *cun* below the medial thigh is needled too deeply, enuresis results.
