Whenever the body's blood and qi are weak, and the zang-fu organs are deficient and emaciated, one is invaded by "ghost qi" (pathogenic factors causing consumptive diseases), thereby contracting this evil and developing *Chuan Shi* (a contagious, consumptive disease). The manifestations include incessant coughing, chest and diaphragm distension and oppression, limb pain, emaciation of the skin and flesh, inability to ingest food, irregular vomiting and diarrhea, expectoration of pus and blood, craving for water or beverages, a tendency to sing or chant, a predisposition to sadness and sorrow, intermittent episodes of wind-stroke or epilepsy, or difficulty in urination and defecation. Some contract it due to alcohol and food intake, some due to exposure to wind and rain, some through visiting the sick or attending funerals, some through casual wandering day and night, some due to qi stagnation, some due to blood stasis; some sleep exposed in fields, some meet casually in gardens, absorbing the miasma of death and disease from these sources, thus becoming ill. Hence it is called *Chuan Shi*.

The Liver and Gallbladder are exterior-interiorly related, with the Foot-Jueyin Liver Channel and Foot-Shaoyang Gallbladder Channel being their respective meridians. The Liver governs Spring, which is the beginning of all things' growth; its qi is tender, soft, empty, and expansive. Therefore, its pulse is wiry and soft. Sweating therapy should not be used at this time; if the pulse is weak, purgative therapy should not be used. A wiry and long pulse indicates normality (Ping); deviation from this indicates pathology. A pulse that is deficient and wiry indicates excessiveness, with the disease located externally; excessiveness causes forgetfulness and sudden dizziness or vertigo. A pulse that is solid but faint indicates deficiency, with the disease located internally; deficiency causes distension and fullness in the chest and hypochondrium. Generally, Liver Excess draws pain to both hypochondriac regions; with rebellious qi, it causes headache, deafness, and redness of the cheeks, with a deep and rapid pulse. A floating and rapid pulse presents similarly, primarily manifesting as flank support-fullness, difficult urination, headache, and vertigo. If the pulse is extremely rapid, the patient dislikes speaking; if slightly rapid, qi stagnates under the flanks; if extremely slow/relaxed, there is vomiting and reflux; if slightly relaxed, it primarily involves the Spleen; if extremely wiry, internal abscesses and hematemesis occur; if extremely excessive, tendon bi-syndrome occurs; if extremely small, there is polydipsia; if minute, Xiao Bi (wasting-thirst bi) occurs; if extremely slippery, Tui Shan (scrotal hernia) occurs; if slightly slippery, enuresis occurs; if extremely choppy, fluid retention flows freely; if slightly choppy, muscle cramping occurs. Furthermore, accumulated Qi in the Liver lingering in the hypochondrium for a long time will trigger coughing and reflux or become malaria. When the Liver is Deficient, one dreams of lush grass and flowers; when Solid, one dreams of flourishing mountains and forests. Additionally, Liver disease manifesting as headache, vertigo, limb fullness, retraction of the scrotum, and urinary obstruction leads to death within ten days. Another presentation includes fever with aversion to cold, immobility of the four limbs; the pulse should be wiry, long, and rapid, but instead is short and choppy, indicating Metal overcoming Wood, leading to death within ten days, untreatable. Cold invading the Liver causes inability to raise both arms, dryness of the tongue root, frequent sighing, chest pain preventing turning of the body, with a slow and choppy pulse at the left Guan position. Heat invading the Liver causes panting and fullness, irritability, eye pain, abdominal distension, anorexia, erratic behavior, nocturnal fright, red eyes, and blurred vision, with a Yin-Solid pulse at the left Guan position. Cold-Deficiency of the Liver causes hardness and pain in the hypochondrium, blindness, arm pain, chills resembling malaria, anorexia, amenorrhea in women, and急促 breathing, with a deep and weak pulse at the left Guan position.
