But at present, the human reproductive process is increasingly restricted by human factors, and caesarean section is the most common one. In order to reduce the pain of childbirth, people increasingly like to cut a knife in the abdomen and take out the baby. When to take the baby out of the mother's womb is completely artificial, so the birth time of caesarean section has lost its natural significance and can no longer objectively reflect the time of the baby's birth and the movement law of the gas field, so it is impossible for a caesarean section person to predict his life with the eight-character method.
Except for caesarean section, the life expectancy of all people born by human intervention in the process of fertility cannot be predicted by the eight-character method. For example, induced labor, induced abortion and other methods will change the time of birth, and the life span of people born through these methods cannot be calculated by the eight-character method.
