Label copy
The froms of the bi (circle) and cong (square) date back to the stone age in China but their original meaning, function, and names are unknown. In the succeeding Bronze Age cultures of the Shang (ca. 1600-1050 BCE) and early Zhou dynasty, cong and bi are rarely found. Unearthed in greater numbers in later Zhou sites, they gained importance in the following Han dynasty, where they were at the core of the earliest Chinese books on philosophy, cosmology, and metaphysics. The Zhou Li (Book of Rites), an ancient Chinese book, compiled by the Zhou dynasty and amended during the Han dynasty (206 BCE- 220 CE), describes the cong as a symbol of earth (square) and the bi as the symbol of heaven (circle).
