In fact, there have long been records about Kunlunnu, and even in the Eastern Jin Dynasty, there was a Kunlun nu named Li Lingrong, who also created a miracle. She eventually became a concubine of Sima Yu, the Jianwen Emperor of the Eastern Jin Dynasty, and gave birth to Sima Yao, the Emperor Xiaowu of the Jin Dynasty, who was later honored as "Empress Wen". According to reports, Li Lingrong's appearance is "long in shape and black in color", which is called "Kunlun".
From this account of the Eastern Jin Dynasty, it can be seen that Kunlun nu did not refer to black people. Because in ancient times, the word Kunlun generally referred to the black things outside the Kunlun Mountains, which was nothing more than a black skin color! Adding a slave means that the occupation is relatively low, such as Li Lingrong, who works "in the weaving mill".
However, in the Tang Dynasty period, due to the unprecedented strength of the Tang Dynasty, especially Chang'an City, which was the premier international metropolis at that time, attracted people from all over the world, naturally including some Nanyang people with African characteristics, etc., which formed the Tang Dynasty version, and the influence of kunlun nu to this day.
Therefore, to find out whether Kunlun nu are black or not (this question should refer specifically to very black people), we must first look at the profession they are engaged in. Because of the word "slave", it limits him to those occupations of relatively low status.
For example, mariners and other marine professions, in the "Pingzhou Can Talk", there is such a sentence: the ship suddenly leaks, that is, it cannot be treated, so that the ghost slave holds a knife to make up for it from the outside. Ghost slaves are good at swimming, and they are not blind to the water. That is, Kunlun Nu is not only good at repairing boats, but also good at swimming!
Therefore, this record proves that the possibility of being black is relatively small, because black people can swim and repair boats is too small, let alone during the Tang Dynasty. On the contrary, those races in Southeast Asia are good at doing this kind of work.
In addition to repairing boats and good water, Kunlun Nu is also a song and dance expert! This point is actually not illustrative, there are too many people who are good at singing and dancing, and during the Tang Dynasty, even Li Shimin had to jump up when he was happy. For example, in order to make the old man Li Yuan happy, Li Shimin danced with the TurkIc Khan. Therefore, this does not prove that Kunlun Nu is black.
And what other taming of animals, planting land for the landlord's family, and so on. Obviously, from a professional point of view, the possibility that Kunlun nu is black (African) is quite small.
