author
Known by the pen name Banyunyou, this writer survives in the record mainly through a single late-imperial Chinese novel, Yin feng xiao (引鳳蕭). The scarcity of firm biographical details gives the work an added air of mystery.

by Banyunyou
Banyunyou appears to be the pen name 半雲友, also given in some records as 楓江半雲友. Reliable catalog and archive listings connect that name with the Chinese novel 引鳳蕭 (Yin feng xiao), and Project Gutenberg currently lists this as the author's known work.
Beyond that, clear personal details are hard to verify. Available library, archive, and ebook records identify the author by pseudonym rather than a confirmed personal name, and they do not provide dependable information about birth, death, or life events.
That means Banyunyou is best approached through the surviving book itself: a writer from the world of classical Chinese fiction whose identity remains shadowy, but whose work has continued to circulate through modern library and public-domain editions.
