Xianshisheng is the author of the book Guyi of Constitutional Law (Xianfa Guyi). The author's real name, nationality, and dates of birth and death are not clearly recorded, and publicly available information is very limited. What can be confirmed is that the library holds one work by this author, namely Guyi of Constitutional Law, which is generally classified under law. Judging from the title, the book centers on the theme of constitutional law and adds the phrase "gu yi" (ancient meanings), suggesting that the author may focus on the historical origins and traditional interpretations of constitutional ideas, attempting to trace their original meaning within the context of Chinese and foreign constitutional thought, or to explain the fundamental spirit of constitutional law through traditional scholarly approaches. Because direct materials on the author's life and the background of the book are lacking, it is difficult to determine the author's motives or scholarly stance, and excessive speculation about the book's views is inadvisable. For readers studying constitutional doctrine, the book may serve as a textual clue for understanding related issues, while its specific content and influence remain to be further verified.
