During the Spring and Autumn Period and the Warring States Period, were there any grades for princes and concubines?
Roughly as follows:
Spring and Autumn Period: Wife: Madam, Princess Yuan, country name+surname ()
Concubines: upper concubines, second concubines, lower concubines, second concubines (all of which are called by different countries), concubines (said to exist), country name+surname (such as Qi Jiang), ranking+surname (such as,), country name+female (such as Qin, Yan and Wei).
Warring States period: wife: there were wives in use in the early days. Kings of all countries are kings and naturally queens;
Concubine room: such as madam (it is said that there are), a certain lady (at this time, a certain surname), beauty, country name+surname, country name+female.
So Mrs. So-and-so is not common. It should be your respectful name. Some girl is a little more complicated. A word can be a country name, a father's surname or a husband's surname. Ji can refer to her surname or simply to a woman.
If there are differences in grades, it is impossible to know each other's names because there are few records in this period. At that time, it was a time of war, and bamboo slips were also used to record national military and political events, or to pass books between monarch and minister, so it was impossible to record the harem.
In the Han Dynasty, the parallel system of counties and countries was implemented (county+enfeoffment system), the supreme ruler was the emperor, and only the Han Dynasty had princes; In addition, concubines in this period refer to concubines below the level of beauty, and also refer to women.
