Gong said that in Gong Dou, what is the generation (mistake) of the prince and the princess, that is, the prince and the princess are arranged separately (that is, the eldest prince, the second prince, and then big princess)

Generally speaking, the rank of princes is determined according to their age and birth order. For example, the eldest son of the emperor will be named "eldest son", the second son will be named "second son", and so on. If there are multiple princes and princesses at the same time, they are sorted by age and birth order. The oldest prince will be named "the eldest son of the Emperor" and the oldest princess will be named "big princess".

However, in some cases, the qualifications of a prince and a princess may be calculated separately. For example, in the Qing dynasty, the rank of a prince was determined according to his father's identity. If the prince's father is an emperor, he will be named "Prince"; if his father is a prince or a county king, he will be named "Prince". The rank of princesses is determined according to their mother's status. If the mother of a princess is a queen or a concubine, she will be named "Princess", while if her mother is a concubine or a maid-in-waiting, she will be named "Princess".

In a word, in the palace fight, the ranks of princes and princesses are determined according to their status, and the specific sorting methods and rules may change with the changes of the times and dynasties.
