active 18th century Xuan Wu

Very little biographical information is easy to confirm about this author beyond the basics. Project Gutenberg lists him as Wu, Xuan, active in the 18th century, and gives several alternate forms of the name, including Wu Hsüan, Wu Hengzhang, Dongyuyishi, and 吳璿.

He is chiefly associated with Fei long quan zhuan (Flying Dragon Complete Tale), a Chinese historical novel. A reliable catalog record attributes the work to "Dongyuyishi," while other library and book sources connect that name with Wu Xuan/吳璿, suggesting it was one of the names under which he was known.

Sources describing the novel say it was produced in the Qing dynasty, during the Qianlong period, and that Wu Xuan expanded and adapted an earlier version of the story. The book follows Zhao Kuangyin through adventure, warfare, and eventual accession to the throne, blending heroic legend with historical storytelling in a style that kept older popular narrative traditions alive.
