Lee's Joseon really played the Jurchen Cult to the extreme, and the king not only mistreated his own daughters, but also the mothers of their children were not worthy of pretending to be mothers in front of their children. Emperor Hyojong of Joseon had six daughters, five of whom were princesses from Queen Inseon and one from Ann. Every time Emperor Xiaozong rewarded him, he only gave five princesses, and did not have the share of the one who was the lord of the house. Or Empress Renxuan could not see it, and paid her own money to subsidize the reward of the concubine. It is said that Emperor Xiaozong's purpose in doing so was to make the lord thank his mother-in-law.
This is not the most bizarre, the most extreme one is that An Concubine once called her own daughter Shu Ning Weng "you", and When Emperor Xiaozong found out, he was furious and even planned to kill An Concubine. Because he felt that An Concubine was only a concubine, not a middle palace, and was not qualified to claim to be the mother of the lord. Later, it was Only after Empress Renxuan interceded that She spared Concubine An.
Emperor Xiaozong himself was harsh on his daughters, but he was very kind to his two younger brothers. It is precisely because of his statement that the princesses and palace people behind the concubines do not dare to talk about these two princes. The side also reflects how bad the Korean Consort Cult is, and even the princes of shu chu have been despised by the palace people.
