After the fall of the Tang dynasty, subsequent regimes paid little heed to Guanzhong when choosing their political centers or capitals. From that time on, no dynasty ever again established its capital in the region. Once hailed as a land of strategic and material abundance—“a terrestrial and celestial granary”—Guanzhong gradually declined and slipped from the national consciousness. This decline had already begun to manifest in the waning years of the Tang. The silting and obstruction of canal systems made it increasingly difficult to transport grain from the prosperous southeast to the northwest. At the same time, the region suffered repeated invasions from foreign powers and disruptions from unruly regional warlords, turning Guanzhong into a frequent battlefield. Its former prosperity naturally faded into memory. As the Tang dynasty drew to a close, even an episode of capital relocation took place: Zhu Wen, under the pretext of protecting Emperor Zhaozong, coerced the court into moving from Chang’an to Luoyang. This move laid bare the reality that the once-glorious Guanzhong—once praised as both “land and sea” and “heaven’s granary”—could no longer command the political loyalty or emotional attachment of the empire’s rulers.
