Ruan Zhenqi is an author about whom public information is limited. The identity details currently available are mainly connected with the documentary work Panda Qizai. Classified as documentary literature, the book suggests that the author tends to base writing on real subjects and to develop the narrative through observation and recording rather than fictional imagination. The title refers to an individual giant panda, giving the work a clear natural and animal-documentary character and indicating the author's interest in wildlife protection and the lives of individual animals. At present, Ruan Zhenqi's nationality, dates of birth and death, education, and other writing experience cannot be confirmed, and only this one work is included in the library. A fuller understanding of the author therefore depends on further public information, yet the documentary approach and animal subject of this work already offer readers a concrete point of entry for observing the relationship between humans and nature.
