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.
Xunzi (book) The Xunzi ( ; ) is an ancient Chinese collection of philosophical writings attributed to Xun Kuang, a 3rd century BC philosopher usually associated with the Confucian tradition. The "Xunzi" is perhaps most famous for the emphasis it places on education and propriety, as well as its striking assertion that “human nature is detestable.” The text is furthermore an important source of early theories of ritual, cosmology, and governance. The ideas within the "Xunzi" are thought to have exerted a strong influence on Legalist thinkers, such as Han Fei, and laid the groundwork for much of Han Dynasty political ideology. The text criticizes a wide range of other prominent early Chinese thinkers, including Laozi, Zhuangzi, Mozi, and Mencius.
