Why is Amar's wife not the Empress and her husband the Empress?

First of all: Ama is the title of Manchu people for their father. In the Qing Dynasty, only one father (grandmother) could be emperor in each generation, and other ordinary grandmother's wives could only be ordinary nuns, and they could not take the word "emperor". Secondly, if this grandmother is the emperor, she is called the emperor's grandmother by the emperor and his daughters, but the feudal hierarchy stipulates that only the queen of the palace can be called the emperor's queen by all emperors and daughters, and other concubines can only be called queens by their own children, but not by their own children. If this woman's status is not high, even her own children can only call her mother when no one is around (because she is not even qualified to raise children). Therefore, as a prince or an emperor's daughter who is not from an official palace, her own mother-in-law is not an emperor's mother, and her husband is an emperor's mother. As for your question, "Why is grandma's wife not her mother?" Well ... you have many wives of Ama, which one are you talking about?
