Ku Ling is an author included in Chinese book reference materials, but public information about this author is limited. Their nationality, dates of birth and death, and English name are not clearly recorded, and only one work by this author is currently held in the collection. According to the available information, Ku Ling's representative work is A History of Shanghai (2 volumes). The book is classified as a historical reader and deals with the history of the city of Shanghai. It is presented in two volumes, making it easier for readers to follow the development of Shanghai over time or by theme. Because very little verifiable material about the author's life is available, it is difficult to determine their academic background or writing approach, and it is also impossible to confirm whether they have written other works. As far as this work is concerned, it is aimed at general readers interested in the local history of Shanghai and falls within the category of popular historical writing. It can serve as an introductory reader for understanding the historical development of Shanghai. Given the incomplete information about the author, readers may wish to rely mainly on the work itself and read it alongside relevant historical sources.
