The chances of having a normal birth of a dragon and phoenix child are around 1 per thousand to 5 per thousand. The term “dragon and phoenix” refers to twins of different sexes, which are dizygotic twins with a probability of around 1 per 1,000 to 5 per 1,000. Twins consist of two eggs that combine with sperm at the same time to form two fertilized eggs, which implant in the uterus and mature separately. These twins may have their own placentas, which are in their own sacs, and the blood circulation between the two placentas is not connected, and the sex and blood type of the fetuses can be different. The chances of having twins by natural conception are small, but for those suffering from infertility, IVF can be used to increase the probability of having twins. Women are advised to go to the hospital regularly for maternity checkups and ensure enough rest. Pay attention to a balanced diet and eat more foods containing protein and vitamins such as milk, fish, spinach and oranges under the guidance of a nutritionist.
