Why did Gege have no children after she got married in the Qing Dynasty?

Looking through the medical records and history books of the Qing Dynasty, we can find a phenomenon that Gege seldom gave birth to children, and nine times out of ten she died of lovesickness. Gege, Manchu, means miss. As a unified address for the daughters of the Qing royal family, it is also used to address other distinguished women. The junior concubine of the prince of the Qing Dynasty is sometimes called Gege. After the birth of Gege girls in Qing Dynasty, they were generally cared for by wet nurses, and rarely saw their biological mothers. From birth to marriage, mother and daughter meet only a handful of times. A phenomenon can be found in the history books of the Qing Dynasty: Gege in the Qing Dynasty rarely gave birth to children, and nine out of ten died of lovesickness, because it was difficult for them to see their husband and wife on weekdays. According to the royal rules, when the princess got married, she was given a house to live outside the palace, accompanied by a maid. The nurse is usually a close friend of the Queen's family. But you can't live with Xu's brothers and sisters. Because, although married, Gege is still Gege, and respect cannot be chaotic. Therefore, husbands can only live in the outbuilding of Gege House, not as close as folk couples. When parents-in-law want to see Gege's daughter-in-law, they should kneel three times and knock nine times. At the same time, because of the noble status of the princess, I believe that "getting drunk and hitting the golden branch" has been heard. Xu can't stay away from the princess every day and visit her. It costs a lot of money for the princess to meet Xu because the power is in the hands of the wet nurse. If the princess doesn't bribe the nurse, the nurse will stop her and even call the princess shameless. Gege grew up under the control of these wet nurses, most of whom were timid and shy. How dare they argue with each other? They are dominated by others. When I had the opportunity to face my mother, I felt very distant and embarrassed to ask. So many gege are depressed and lovesick. If Gege doesn't bribe the wet nurse, even if Gege makes a phone call, the wet nurse will find an excuse to stop it in many ways and even blame the ridicule. As a young woman in feudal society, Gege was weak and shy, and dared to fight for it, so she had to be at the mercy of her wet nurse. Even if they went to visit their mother in the palace, that is, their imperial mother, Gege was ashamed to say so. Because I can't reunite with Xu for a long time, not only the chances of having children are few, but many Gege also died young because of long-term illness.
