Xuanji (CV21) is located in the depression one cun below Tiantu (CV22). It should be accessed with the patient in a supine position. The needle insertion depth is 0.3 cun, and moxibustion consists of five moxa cones.
Indications include fullness in the chest and hypochondrium, cough with rebellious Qi, asthma so severe that speech is impossible, throat obstruction with swelling, and difficulty swallowing fluids.
The *Yulong Fu* states: When combined with Qihai (CV6), it treats emaciation and rapid panting.

The *Baizheng Fu* states: When combined with Shencang (BL45), it effectively treats fullness in the diaphragm and stiffness of the neck.

Tiantu (CV22), also known as Yuhu, is located in the depression three cun below the laryngeal prominence. It is the meeting point of the Yin Linking Vessel (Yinwei Mai) and the Conception Vessel (Ren Mai). The needle insertion depth is 0.5 cun; retain the needle for three breaths, and apply three moxa cones. The *Jia Yi Jing* states: Access the point with the head lowered, inserting the needle one cun deep.
Indications include rebellious Qi, asthma, cough, throat obstruction, the "Five Chokes" (Wuye), lung abscess with expectoration of pus and blood, acute sore throat with loss of voice, alternating chills and fever, dry throat with tension under the tongue, and inability to eat.
The *Shennong Jing* states: It treats asthma and cough; seven moxa cones may be applied.
The *Yulong Fu* states: When combined with Danzhong (CV17), it treats cough.
The *Lingguang Fu* states: It treats asthma with phlegm.
The *Baizheng Fu* states: When combined with Feishu (BL13), it treats continuous coughing.

Lianquan (CV23), also known as Benchi or Sheben, is located in the center above the laryngeal prominence and below the root of the tongue on the mandible. It should be accessed with the patient in a supine position. It is the meeting point of the Yin Linking Vessel (Yinwei Mai) and the Conception Vessel (Ren Mai). According to the *Cinema Pian* chapter on Malaria Needling: "The vessels on both sides under the tongue" refer to Lianquan. The *Qifu Lun* states: "One acupoint on each side under the tongue belonging to the Foot-Shaoyin Kidney Meridian." The *Weiqi Pian* states: "The biao (marking) of the Foot-Shaoyin lies in the back and the vessels on both sides under the tongue." Therefore, Lianquan is not a single point but refers to the left and right vessel points at the base of the tongue, which are also the meeting points of the Foot-Shaoyin Kidney Meridian. The needle insertion depth is 0.3 cun; retain the needle for three breaths, and apply three moxa cones.
Indications include cough, wheezing, and rebellious Qi; spitting saliva; flaccid or protruding tongue; swollen tongue making speech difficult; retracted tongue root leading to anorexia; and mouth ulcers resulting from the retreat of saliva.
The *Baizheng Fu* states: When combined with Zhongchong (PC9), it can treat swelling and pain under the tongue.

Chengjiang (CV24), also known as Tianchi or Xuanjiang, is located in the depression anterior to the chin and below the lower lip ridge. It is the meeting point of the Foot-Yangming Stomach Meridian and the Conception Vessel (Ren Mai). The needle insertion depth is 0.2 cun; retain the needle for five breaths, and apply three moxa cones.
Indications include hemiplegia due to wind-stroke, deviation of the mouth and eye, trismus (lockjaw), acute loss of voice. Insert the needle 0.3 cun and slowly guide the Qi outwards. It also treats diseases of the Conception Vessel, characterized by internal knotting of suffering: in men, it manifests as the Seven Hernias (Qishi); in women, as masses (Jiaju). Another view holds that it treats facial swelling from wind-stroke deviation, excessive thirst and drinking in Xiao-ke (wasting-thirst syndrome), and mouth/tooth canker sores. Moxibustion is also beneficial: seven cones daily up to forty-nine cones will promote blood and vessel circulation, causing the wind pathogen to disperse immediately. The moxa cone need not be large; as long as it targets the vessel, the disease will be cured.
The *Qianjin Fang* states: For infants with tight lips, apply three moxa cones. It further states: For hiccups causing distress, apply seven moxa cones the size of a wheat grain. Additionally, in the Thirteen Ghost Acupoints system, this point is named Guishi (Ghost Market) and treats various pathogens causing mania and epilepsy; it should be needled during the eighth step.
The *Baizheng Fu* states: Reducing this point relieves toothache and shifts the pathological process.
The *Tongxuan Fu* states: It treats stiffness of the head and neck.
