(The arterial pulse on both sides of the laryngeal prominence) belongs to the Foot-Yangming Stomach Meridian. Renying (ST9), located on both sides of the laryngeal prominence, is palpable as an arterial pulse, also known as Tianwuhui. The *Ling Shu* states: "The arterial pulse on the side of the neck is called Renying. Renying belongs to the Foot-Yangming Meridian and is located anterior to the sternocleidomastoid muscle." It further states: "Renying is the site where stomach qi branches off to the Yangming meridian; therefore, the pulsations in the Yin and Yang regions above and below should be consistent. Thus, if a Yang disease presents with a small Yang pulse, it is a counterflow (ni); if a Yin disease presents with a large Yin pulse, it is a counterflow (ni). If both Yin and Yang pulses are either both weak or both excessive, resembling a taut rope tilting to one side, the disease is severe." It also states: "In cases of high fever throughout the body, accompanied by mania, hallucinations of sight, hearing, and speech, one should observe the Foot-Yangming Meridian and its major collaterals for treatment. Let the patient lie supine, situate oneself before the head, use four fingers of both hands to clamp and press the cervical artery, hold it for a long time, then curl the fingers to cut and push downwards to the Quepen (ST12) area, stop as before, until the heat dissipates. This is what is referred to as 'pushing and dispersing'." Wang Qixuan said: "The Yang qi of the stomach cavity is the qi of Renying. As the Stomach is the Sea of Water and Grain, observing its qi allows one to know the location of pain. The pulsation of the Renying pulse is usually smaller on the left and larger on the right. A smaller left pulse typically diagnoses Zang organ diseases, while a larger right pulse typically diagnoses Fu organ diseases." Pang Anchang said: "The key to pulse diagnosis lies most urgently in Renying and Qikou; these two pulses correspond to each other like two parallel ropes. What is Renying? It is taken at the side of the throat, which the *Nei Jing* calls 'distinguishing from Yang'. Qin Yue-ren (Bian Que) only took the point 1.9 cun posterior to the Yuji (LU10) of the Hand-Taiyin Lung Meridian to match the numbers of Yin and Yang, thereby obtaining the Guan-Ge pulse pattern. However, without comprehensively selecting various acupoints and first seeking the meaning of the throat and hand pulses corresponding like a taut rope, one would remain ignorant of the origins of Cun-Cun pulses, Yin-Yang, and Guan-Ge." Furthermore, Renying collectively governs the Six Yang Meridians of the Hand and Foot. The *Ling Shu* states: "If the Renying pulse is one-fold greater than the Cunkou pulse, the disease is in the Foot-Shaoyang Gallbladder Meridian; if one-fold greater and restless, the disease is in the Hand-Shaoyang Sanjiao Meridian. If the Renying pulse is two-fold greater, the disease is in the Foot-Taiyang Bladder Meridian; if two-fold greater and restless, the disease is in the Hand-Taiyang Small Intestine Meridian. If the Renying pulse is three-fold greater, the disease is in the Foot-Yangming Stomach Meridian; if three-fold greater and restless, the disease is in the Hand-Yangming Large Intestine Meridian. If the Renying pulse is four-fold greater, and both large and rapid, it is named Yi Yang (Overflowing Yang). Yi Yang constitutes Wai Ge (External Gridlock), which is a death case difficult to treat." It also states: "Cunkou primarily reflects internal conditions, while Renying primarily reflects external conditions. They should correspond to each other, coming and going together, with equal magnitude. In spring and summer, the Renying pulse is slightly larger than the Cunkou pulse; in autumn and winter, the Cunkou pulse is slightly larger than the Renying pulse. Such a person is considered a Ping Ren (healthy person). When a person is ill, if the Cunkou pulse and the Renying pulse are equal in magnitude and floating/sinking depth, the disease is difficult to cure."
