Small jade, a person who does not exist in history, is a person in literary works, and her identity is Dourgen's wife. Although Small jade is not a real person, she didn't appear out of thin air. There are prototypes of her in history. This person is one of Dourgen's wives, and the other is Mongolian.
Small jade always knew that Dourgen liked his sister, but you never knew that the two of them were forced to separate and were used by Khan to marry Dourgen. But she doesn't care whether she is used or not, because it is her wish to marry Dourgen.
Later generations, through historical records and other evidence, believe that Small jade's prototype is the Mongolian daughter adopted by Huang Taiji, who later became the wife of Dourgen. Because the prototype of Small jade came from the grassland, people shaped this character into a little strong sister, which highlighted the ups and downs of the plot and attracted more audiences.
