The short text is an enlarged edition of an earlier version called Xishi xianwen 昔時賢文 "Writings of worthies from old times" or Gujin xianwen 古今賢文 "Writings of worthies from ancient and modern times". When the original version and the enlarged text were compiled, and by whom, is unknown.

The Zengguang xianwen was circulating in different versions and different texts, but in all editions the text is written in rhymed pairs of sentences. The quality and structure of the various paragraphs differs widely and makes it a very heterogeneous book, but it was nevertheless widely circulating during the late Qing period 清 (1644-1911). During the Tongzhi reign-period 同治 (1862-1874), Zhou Xitao 周希陶 rearranged the book and ameliorated the textual quality. The most important edition was published by the Shanghai Putong Shuju 上海普通書局.
