The verity of Shuangqing,who was recorded in Xi Qing San Ji,has been controversial for a long time.In recent years,the view that she was a real historical figure became mainstream gradually.By analyzing the text of Xi Qing San Ji itself and external documents further,it can be seen that historical materials recording Shuangqing are unreliable,as the author Shi Zhenlin didn't have the spirit of chronicle during his writing process,and the fictionality of Shuangqing not only conforms to logic and the stylistic rules and layout but also is based on historical precedents.One of the motives of fabrication with which Shi Zhenlin portrayed the fictional image was the tradition of indication called"men make the boudoir sounds"by the background of the same structure of the clan and country,while the other was the request to cover up his intention of indication to seek safety at the specific historical background.
