A nodule appearing first in the left breast indicates a male child. A nodule appearing first in the right breast indicates a female child.
Another method: Have the pregnant woman walk facing south, and call her from behind. If she turns back to the left, a male will be born; if she turns back to the right, a female will be born.
If there is continuous vaginal bleeding accompanied by a dry uterus (Baogong), the fetus will die, and the mother's life will also be endangered.
If there is acute pain in the heart and abdomen, cyanosis of the face and eyes, spontaneous cold sweat, and breath nearly failing, death will occur.
If there is continuous vaginal bleeding, fetal Qi rushing upward, and coldness and numbness in the four limbs, death will occur.
If heavy lifting or falling causes the fetus to die in the womb without being expelled, and vaginal bleeding continues with blood rushing to the heart causing chest tightness and severe pain, death will occur.
If chills and fever occur frequently, the veins under the tongue are blue-black, the tongue curls up and feels cold, both mother and child will die.
If the lips and mouth are cyanotic, and phlegm-foam is vomited out, both mother and child will die.
If the face is red and the tongue is cyanotic, the mother survives while the fetus dies.
If both the face and tongue are cyanotic, and phlegm-foam is frequently discharged, the fetus survives while the mother dies.
If the face is cyanotic and the tongue is red, with saliva flowing from the mouth, the mother dies while the fetus survives.
For children aged three to five years, diagnosis primarily relies on observing physical signs. For children over five years old, pulse diagnosis gradually becomes feasible. A normal pulse rate is eight beats per respiration cycle. Nine beats indicate illness. Ten beats indicate critical condition. (Xu believed that using the thumb to palpate the Cun, Guan, and Chi positions on all three positions, ten beats indicate fever, and five beats indicate internal distension.)
A floating and rapid pulse in children indicates diseases such as nursing epilepsy and wind-heat.
A floating and rapid pulse in children indicates stagnation of the Five Zang organs (caused by overheated milk or excessive cotton clothing).
A deficient and choppy pulse in children indicates convulsions due to fright. (Furthermore, a floating pulse indicates wind pathogen, and a hurried and urgent pulse indicates deficiency-induced fright.)
A tight pulse in children indicates wind epilepsy.
A tight and wiry pulse in children indicates abdominal pain and restlessness.
A wiry and urgent pulse in children indicates disordered Qi circulation.
A deep, firm, and excess pulse in children indicates constipation of the Large Intestine.
A deep and rapid pulse in children indicates cold in the bones. (This rapid pulse is due to deficiency; deficiency leads to insufficient marrow, hence cold in the bones.)
A deep and thin pulse in children indicates cold syndrome.
An irregular pulse in children, varying in size from large to small, suggests misfortune or evil influences.
A small, slow, or deep pulse in children indicates indigestion.
During the period of "Bian Zheng" (developmental changes) in infants, symptoms include body heat, chaotic pulse, sweating, refusal to nurse, and vomiting after feeding. Medical intervention should be avoided as it will self-heal. (Signs include body heat, confusion, vomiting milk, passing yellow foam, excessive crying without joy, and white bead-like formations on the upper lip. There is a change every 32 days, and a combined change at 64 days. Changes may also occur at 28 or 30 days without fixed regularity, ceasing around 25 months. After cessation, the infant's spirit and demeanor will differ from before.)
