the text, also known as Classic of Changes, excavated in 1977 from the Shuanggudui archeological site is called what?
Shuanggudui Shuanggudui () is an archeological site located near Fuyang in China's Anhui province. Shuanggudui grave no. 1, which belongs to Xiahou Zao (), the second marquis of Ruyin (), was sealed in 165 BCE in the early Han dynasty (206 BCE – 220 CE). Excavated in 1977, it was found to contain a large number of texts written on bamboo strips, including fragments of the "Classic of Poetry" and the "Songs of the South", a text on breathing exercises, a "year table" () recounting historical events, a manual on dogs, a version of the "I Ching" ("Yijing") that differs from the received one, and artifacts including the oldest known cosmic board, a divinatory instrument. Like Mawangdui and Guodian, two other tombs from the area of the old state of Chu, the Shuanggudui find has shed great light on the culture and practices of the early Han dynasty.
Sushui Jiwen The Sushui Jiwen (涑水記聞; "Records of Rumours from Sushui") is a book written by the Song Dynasty historian Sima Guang (1019–1086) in imperial China. While working with (劉道原) and others to compile a never-published "Zizhi Tongjian Houji" (資治通鑑後記), a book on the Song Dynasty history, Sima Guang collected many miscellaneous anecdotes. While he might have intended to include them in "Tongjian Changbian", the "weird" stories became "Sushui Jiwen" in 1180 after his death. The Sushui (涑水; "Su Water") is a small tributary of the Yellow River, and Sima Guang was nicknamed Mr. Sushui (涑水先生) as his hometown of Xia County is on the Sushui. Because the book was compiled by later editors, the number of chapters vary according to the edition: one has 10 chapters, another has 2, and the one in "Siku Quanshu" has 16 — although many repetitions occur in ch. 9–13.
