Emperors in ancient China always liked to add strange visions to their births to prove that they were the chosen ones. In the flood era when animals were "allowed" to become sperm, this legend was even more so.
Legend has it that Dayu's mother, after a week of labor, gave birth to a "stone fetus", and a baby popped out of the stone fetus, which was Dayu.
The level of knowledge of the ancients was limited, and if he knew what a "stone tire" was, he would regret making himself into such a thing.
The phenomenon of "stone tires" does exist in medicine. It is a special form of intra-abdominal pregnancy, accounting for about 1% of intra-abdominal pregnancy. Abdominal pregnancy is a special form of "ectopic pregnancy", which refers to the implantation of embryos in the abdominal cavity. It occurs in about 1 in 15,000 and tends to occur after a miscarriage or rupture of a tubal pregnancy (secondary intraperitoneal pregnancy).
Fetuses over 12 weeks of age, because the bones have formed, cannot be completely dissolved and absorbed by the mother after death. Over time, calcium in the ascites will be deposited on the surface of the fetus, eventually forming a stone fetus.
From this, we can see that stone tires are very rare. In fact, more than 300 cases have been reported in domestic and foreign literature so far. And with the development of society, there will be fewer and fewer women who have no money to do obstetric examinations/physical examinations, and there will be fewer and fewer stone fetuses.
Although the stone fetus may have been living peacefully with the mother for decades when it was found, it is still recommended to be removed once it is found. Because it still has the risk of damaging the surrounding tissues and organs or causing the organs to be reversed. If you happen to have an elderly person around you who has this condition, be sure to convince her to have surgery
