印璽 (The first character is correctly written as 印. The Shiming says: 'A seal means trust; it implies "according to"—sealing goods according to trust.' The second character has the fanqie si + shi. Cai Yong's Duduan says: 'The Son of Heaven's seal is carved from jade with a crouching tiger knob; in ancient times, the feudal lords shared this term.' The Yue ling says: 'Before the Qin, feudal lords and grand masters of townships all called them seals (xi); from that time onward, only the Son of Heaven was entitled to call it a xi, and feudal lords did not dare use it.' The Chuanguo xipu states: 'Ziying, King of Qin, presented the Imperial Heirloom Seal to Han Gaozu; it was engraved by Li Si with the inscription: "Having received the Mandate of Heaven, may the Emperor enjoy longevity and eternal prosperity."' [螘-豆+虫] has the fanqie chi + zhi).
