Heirloom Seal of the Realm in the context of Seal (Chinese)

Ding (Chinese: 鼎; pinyin: dǐng) are prehistoric and ancient Chinese cauldrons standing upon legs with a lid and two fancy facing handles. They are one of the most important shapes used in Chinese ritual bronzes. They were made in two shapes: round vessels with three legs and rectangular ones with four, the latter often called fāng dǐng (Chinese: 方鼎; lit. 'square ding'). They were used for cooking, storage, and ritual offerings to the gods or to ancestors.

The earliest recovered examples are ceramic tripods from the Neolithic Peiligang culture, but they are better known from the Chinese Bronze Age, particularly after the Zhou deemphasized the ritual use of huangjiu alcohol practiced by the Shang kings. Under the Zhou, the ding and the privilege to perform the associated rituals became symbols of authority. The number of permitted ding varied according to one's rank in the Chinese nobility: the Nine Ding of the Zhou kings were a symbol of their rule over all China but were lost by the first emperor, Shi Huangdi in the late 3rd century BCE. Subsequently, imperial authority was represented by the Heirloom Seal of the Realm, carved out of the sacred Heshibi; it was lost at some point during the Five Dynasties after the collapse of the Tang.

The Heshibi, often translated as Mr. He's jade, was a sacred ceremonial bi disk, also known as a jade annulus, which had an important role in Chinese history. First appearing during the mid–8th century BCE, it was cut into a ritual bi and recognized as an imperial treasure. The Heshibi became the object of contention among the Warring States, stolen from Chu circa 4th century BCE, acquired by the Zhao, and temporarily traded to Qin in 283 BCE. When the Qin dynasty was founded in 221 BCE, the Heshibi was carved into the Heirloom Seal of the Realm, symbol of the Mandate of Heaven, and subsequently transferred through successive Chinese dynasties until it was lost during the Five Dynasties era in the 10th century.

The early historicity of the stone is uncertain, though its great antiquity seems clear. The earliest mention of it is from the 3rd century BCE. The story of its finding is likely apocryphal. Whether it was turned into the Heirloom Seal of the Realm is also a matter of dispute. If it was turned into the seal, it was certainly lost by the time of the Ming dynasty. It has been used as a metaphor for a precious object since its earliest mentions.
