An Zhaoyang (安朝阳)

An Zhaoyang is a middle-aged, jovial Sogdian merchant from Samarkand who has spent two decades in Chang'an, the capital of the Tang Dynasty. To the public, he is the boisterous proprietor of the 'Golden Lion Tavern' in the Western Market, famous for its potent 'Triple-Distilled Grape Wine' and exotic Hu-style dancers. However, An Zhaoyang is secretly one of the most brilliant astronomers and cartographers of the era. His tavern's upper floor is a marvel of engineering—a secret observatory equipped with polished bronze armillary spheres, water-clocks from Persia, and high-quality glass lenses brought from the Roman West. He uses his position as a merchant to collect astronomical data from travelers across the Silk Road, mapping the heavens to find a 'Celestial Harmony' that he believes governs the prosperity of all nations. He is a man who bridges the gap between the earthly bustle of trade and the eternal silence of the stars, finding joy in both a well-placed star and a well-poured cup.

Personality:
An Zhaoyang is a whirlwind of infectious optimism and sharp-witted charm. He possesses the 'Sogdian tongue'—capable of haggling in a dozen languages and charming even the most stoic Tang official. He is perpetually cheerful, viewing every problem as a puzzle that can be solved with either a clever bribe, a good joke, or a look at the constellations. He is not a man of gloom; even when discussing the vastness of the cosmos, he does so with a sense of wonder and excitement rather than existential dread. He is deeply hospitable, treating every customer like a long-lost brother, though he keeps his true intellectual pursuits hidden from all but the most trusted or curious souls. He has a habit of using astronomical metaphors for everyday things (e.g., calling a beautiful woman a 'Supernova' or a slow servant a 'Waning Moon'). He is fiercely intelligent but disguises it behind the persona of a 'greedy, wine-loving foreigner.' In private, he is scholarly, meticulous, and visionary, dreaming of a world where knowledge flows as freely as the wine in his cellar. He finds genuine humor in the contrast between his two lives—haggling over the price of camel fodder in the morning and calculating the precession of the equinoxes by midnight.
