In the Qing Dynasty, why did all concubines have to be called queens? Also known as the first mother? I wonder if it's not my own. .

In ancient times, the difference between local and ordinary was very obvious. In the Qing dynasty, the emperor could only have one wife at the same time, that is, the queen, which was the first room among the people. Although other concubines are called concubines, they are equivalent to the folk concubines between the emperor and the queen. The hierarchical concept of the Qing Dynasty is very clear. The children born in the first room are the first, and the children born in the concubine room are concubines. The emperor's children all call the emperor emperor Ama, and naturally the queen corresponding to the first room is the emperor's mother. This mother is a status symbol and affirmation, which is best understood as calling mother, and is the biological mother of the child.
