Princess Jingning is a character in the original online version of "Nirvana in Fire", the youngest daughter of Emperor Liang; she appeared more in the first few chapters, but then disappeared. By the time the physical book was published, the role had been greatly reduced; in the TV series, this small role was simply deleted. The birth of each character has its own life trajectory, the only difference is whether anyone sees it. For example, the existence of Xiao Jingning does not play a key role in the main plot of the story, but it can make characters such as Mei Changsu and Prince Jing more full and three-dimensional. In this case, I take what others abandon.
