Guanzhong

Guanzhong — "within the passes" — is the Wei River valley shielded by mountains on every side, and its farmland of yellow earth sustained more imperial capitals than any place on Earth. Xianyang served the Qin kings before 221 BCE unification, and Chang’an (modern Xi’an) anchored the Western Han and Tang empires at populations exceeding half a million, making it among the world’s largest cities of its age.

The valley’s soil preserves its grandest secret badly: in March 1974 farmers digging a well east of Xi’an struck a fragment of fired clay, beginning excavation of the Terracotta Army — roughly 8,000 life-size soldiers, chariots, and horses guarding Qin Shi Huang’s tomb, inscribed on the very first UNESCO list in 1987. Westward from Chang’an, Zhang Qian rode out in 138 BCE toward Central Asia, opening the route now called the Silk Road; his reports introduced alfalfa, grapes, and foreign diplomacy to Han courts. Guanzhong cuisine still mirrors the crossroads: hand-slapped biangbiang noodles, mutton soup with crumbled flatbread, and persimmon cakes sold beside Tang-dynasty city walls.
