 Rulers of the Han dynasty (206 BCE–220 CE) were obsessed with building an eternal empire, a humanly-made system that not only mimicked the recurrent pattern of the universe but also responded proactively to the ebb and flow of cosmic forces (Pines 2009, 2012). This everlasting structure was stable and flexible, massive and specific, synchronizing human activities for the unfolding of the universe. Its goal was to merge the natural and human realms, such that the two became one and the same (Loewe 1994, 2005; Wang 2000).
