In Chapter 7 of The Smiling Proud Wanderer, the dying Liu Zhengfeng and Qu Yang bequeathed the zither-and-flute score of the "Xiao Ao Jiang Hu" Song to Linghu Chong, with a wish that it be passed down to future generations. According to Liu Zhengfeng and Qu Yang, a significant portion of the zither score was adapted from "Guang Ling San", a zither melody attributed to Ji Kang of the Western Jin Dynasty (265-316AD).
The earliest written notation of "Guang Ling San"
dates back to 1425AD, when it was found inside the Tai Gu Shen Pin (Amazing Ancient Works), the first half of the two-volume Shen Qi Mi Pu (Amazing Treasured Books) by Zhu Quan. Whether these books were dug out from an ancient tomb, as Qu Yang claimed, or not, cannot be confirmed at this point. However, since the story of the Smiling Proud Wanderer set in the Ming Dynasty (1368-1644AD), the date of the historical discovery of "Guang Ling San" lends a measure of credibility to the re-appearance of the work in the realm of wuxia.
