In those days, as the renown of King Khosrow Anushirvan's justice and authority resonated across every realm, the wise Khaqan of China observed the shifting balance of the world. Understanding that tranquility lay in alliance rather than confrontation with the Iranian throne, he convened a grand council of his ministers, sages, and noble advisers.
Together they deliberated upon how best to win the favor of the Sasanian emperor. The Khaqan commanded his royal treasurer to unseal the high vaults and assemble a tribute beyond measure, worthy of so august a monarch. A magnificent caravan was prepared, laden with fine Chinese steeds of pure lineage, shimmering brocades of silk, ornate imperial thrones, jeweled crowns, razor-sharp blades, and signet rings set with precious gems. To this marvel of riches, he added thirty thousand gold dinars, packed carefully in brocade pouches upon swiftest dromedaries.
To bear these treasures, the Khaqan selected an envoy from among his highest lords—an eloquent diplomat seasoned by travel across the known world. He then summoned an elite scribe to compose a royal letter upon pure silk. The craftsman rendered the document with such luminous artistry that it resembled the legendary Arzhang of China, filling the silk with a hundred thousand blessings and praises dedicated to the Great King Kasra Anushirvan.
