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.
Classic of Mountains and Seas The Classic of Mountains and Seas or Shan Hai Jing, formerly romanized as the Shan-hai Ching, is a Chinese classic text and a compilation of mythic geography and myth. Versions of the text have existed since the 4th century BC, but the present form was not reached until the early Han dynasty a few centuries later. It is largely a fabulous geographical and cultural account of pre-Qin China as well as a collection of Chinese mythology. The book is divided into eighteen sections; it describes over 550 mountains and 300 channels.
