The verse states: The Yin hour corresponds to the Sanjiao (Triple Burner) meridian and the Hand Shaoyang meridian; the Mao hour corresponds to the Large Intestine meridian and the Hand Yangming meridian; the Chen hour corresponds to the Small Intestine meridian and the Hand Taiyang meridian (belonging to Fire); the Si hour corresponds to the Pericardium meridian and the Hand Jueyin meridian; the Wu hour corresponds to the Heart meridian and the Hand Shaoyin meridian (belonging to Fire); the Wei hour corresponds to the Lung meridian and the Hand Taiyin meridian (belonging to Metal); the Shen hour corresponds to the Gallbladder meridian and the Foot Shaoyang meridian (belonging to Wood); the You hour corresponds to the Stomach meridian and the Foot Yangming meridian (belonging to Earth); the Xu hour corresponds to the Bladder meridian and the Foot Taiyang meridian (belonging to Water); the Hai hour corresponds to the Liver meridian and the Foot Jueyin meridian (belonging to Wood); the Zi hour corresponds to the Kidney meridian and the Foot Shaoyin meridian (belonging to Water); the Chou hour corresponds to the Spleen meridian and the Foot Taiyin meridian (belonging to Earth).

When the Foot Shaoyin Kidney meridian and the Foot Taiyang Bladder meridian are simultaneously affected, it is called "Foot Lianggan" (Double Contraction of the Foot meridians). When the Hand Shaoyin Heart meridian and the Hand Taiyang Small Intestine meridian are simultaneously affected, it is called "Hand Lianggan". When the Foot Taiyin Spleen meridian and the Foot Yangming Stomach meridian are simultaneously affected, it is called "Foot Lianggan". When the Hand Taiyin Lung meridian and the Hand Yangming Large Intestine meridian are simultaneously affected, it is called "Hand Lianggan". When the Foot Jueyin Liver meridian and the Foot Shaoyang Gallbladder meridian are simultaneously affected, it is called "Foot Lianggan". When the Hand Jueyin Pericardium meridian and the Hand Shaoyang Sanjiao meridian are simultaneously affected, it is called "Hand Lianggan". "Lianggan" refers to the simultaneous disease of exterior and interior meridians, where both internal and external aspects are afflicted by pathogens. In cases of superimposed pathogenic influence at different stages, one must address the root cause of the disease. The *Suwen* (Basic Questions) states: Why does Shanghan (Cold Damage) lead to death between the sixth and seventh days? It is because of the affliction caused by Lianggan. (Newly added content) Juyang (Great Yang, i.e., Taiyang) is the leader among all Yang meridians; its vessels connect to the Fengfu acupoint (GV16), thus serving as the master Qi of all Yang meridians. When humans are injured by Cold, they develop a Heat disease. Even if the Heat is severe, it will not be fatal. However, those who suffer from Lianggan due to Cold will inevitably die.

On the first day of Shanghan, the Juyang meridian is affected, resulting in headache, stiffness of the neck and back, and rigidity of the lumbar spine. On the second day, the Yangming meridian is affected. Yangming governs the flesh; its vessels run along the nose and connect to the eyes. Thus, there is fever, eye pain, dryness of the nose, and inability to sleep. On the third day, the Shaoyang meridian is affected. Shaoyang governs the Gallbladder; its vessels follow the costal region and connect to the ears. Thus, there is pain in the chest and hypochondrium, and deafness. If the channels of the Three Yang meridians are all diseased but the pathogen has not yet entered the Zang organs, it can be cured by inducing sweating. On the fourth day, the Taiyin meridian is affected. The Taiyin vessels distribute in the stomach and connect to the throat. Thus, there is abdominal fullness and dryness of the throat. On the fifth day, the Shaoyin meridian is affected. The Shaoyin vessels pass through the Kidneys and connect to the Lungs. Thus, there is dryness of the mouth, dry tongue, and thirst. On the sixth day, the Jueyin meridian is affected. The Jueyin vessels circulate around the genitalia and connect to the Liver. Thus, there is vexation, fullness, and retraction of the scrotum. In cases of Lianggan with Cold, the Three Yin and Three Yang meridians, as well as the Five Zang and Six Fu organs, are all diseased. Ying and Wei (Nutritive and Defensive Qi) cease to circulate, and the Five Zang organs become obstructed, leading to death. In cases not involving Lianggan, on the seventh day, the Juyang disease declines, and the headache lessens. On the eighth day, the Yangming disease declines, and the body heat subsides slightly. On the ninth day, the Shaoyang disease declines, and hearing improves slightly. On the tenth day, the Taiyin disease declines; abdominal fullness resolves, and appetite returns. On the eleventh day, the Shaoyin disease declines; thirst stops, abdominal distension ceases, the tongue dries up recovers, and sneezing occurs. On the twelfth day, the Jueyin disease declines; the scrotum relaxes, the lower abdomen feels slightly heavy, the major pathogenic factors have departed, and the illness gradually heals.

In cases of Lianggan with Cold: On the first day, Juyang and Shaoyin are simultaneously diseased, causing headache, dry mouth, and vexation/fullness. On the second day, Yangming and Taiyin are simultaneously diseased, causing abdominal fullness, fever, anorexia, and delirious speech. On the third day, Shaoyang and Jueyin are simultaneously diseased, causing deafness, scrotal retraction, cold extremities, unconsciousness, and inability to take in fluids or food. Death occurs on the sixth day because the Five Zang organs are already damaged.

There follows a method of disease transmission, found at the end of the volume, which expounds upon the "Sanjia Formula." This is not a statement from the *Suwen*, hence it is recorded here.
