The *Zhubing Yuanhou Lun* (Treatise on the Pathogenesis and Manifestations of All Diseases) states: "Nishi" (breech or malpresentation birth) refers to a situation where the mother first feels abdominal pain, but the time for delivery has not yet arrived. Due to fright and disturbance, she exerts force prematurely. Since the fetus has not yet completed its rotation in the uterus, forcing delivery at this stage results in malpresentation. This may also be caused by violating taboos.
The *Jiyan Fang* (Collected Proven Prescriptions) states: For prescriptions treating breech presentation or transverse lie where the fetus cannot be delivered:
Write the child's name on the father's foot sole; then delivery will proceed smoothly.
Another prescription: Apply salt to the soles of the infant's feet. Alternatively, quickly scratch the infant's feet.
