author
Known today mainly through the classic Chinese novel Guigu Siyou Zhi, this little-documented writer is an elusive figure whose work helped keep popular historical storytelling alive. Even the surviving records are fragmentary, which gives the book an added sense of mystery.

by active 18th century-19th century Jingchang Yang
Very little firm biographical information appears to survive about Jingchang Yang, who is listed in modern library records as an author active in the late 18th to early 19th century. Project Gutenberg also records alternate forms of the name, including Yang Danyou and Yang Tan-yu, suggesting that the author has come down to us through variant transliterations and incomplete source material.
Jingchang Yang is credited with Guigu Siyou Zhi (The Four Friends of Guigu), a Chinese historical narrative centered on the legendary disciples Sun Bin, Pang Juan, Su Qin, and Zhang Yi under the master Guiguzi. The novel belongs to the long tradition of Chinese popular fiction that blends history, legend, strategy, and moral drama for a broad reading audience.
Because so little personal detail is securely documented, the author is best approached through the work itself rather than through a full life story. That makes Jingchang Yang one of those intriguing literary figures whose voice survives more clearly than the record of the life behind it.
