Emperor Gaozu of Han
This Qin dynasty jade seal came to symbolize the Mandate of Heaven, and beginning when the last Qin ruler Ziying handed it over to Emperor Gaozu of Han in 206 BCE, it was successively passed on to later dynastic emperors signifying the right to govern the Chinese world. The Heirloom Seal of the Realm was lost sometime between the Tang and Ming dynasties.
