Shuanggudui is an archeological site located near Fuyang in China's Anhui province. Shuanggudui grave no. 1, which belongs to Xiahou Zao (夏侯灶), the second marquis of Ruyin (汝陰侯), was sealed in 165 BCE in the early Han dynasty. 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" (年表) 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.

Fuyang is a prefecture-level city in northwestern Anhui province, China. It is bordered by Henan province to the west and the cities of Bozhou to the northeast, Huainan to the southeast, and Lu'an to the south.
