In " The Return of the Condor Heroes ", Xiao Longnu lied to Valley Master Gongsun that her surname was " Liu " because this plot was to better shape Xiao Longnu's image. Xiao Longnu was originally surnamed Yang, but because of her beauty and legendary experience, Mr. Jin Yong changed her surname to "Long". The image of Xiao Longnu in the novel was very mysterious, proud, and independent. Therefore, her name was also very unique. The name "Xiao Longnu" could make people think of a noble, mysterious, and independent female image. The reason why his surname was Liu was because the name Liu in the novel was a very cultural name. In traditional Chinese culture,"Liu" had the characteristics of "gentle, beautiful, tactful" and so on. Therefore, using "Liu" to describe Xiao Longnu's character and image was also in line with the setting. At the same time, by lying that her surname was "Liu", it could also add some mystery and complexity to the image of Xiao Longnu, making her more elusive and fascinating.
