雍城 / Yongcheng (Qin)
雍城 / Yongcheng (Qin) enters the wiki through 《资治通鉴·秦纪》108-1｜历史敢当面顶撞秦始皇第一人 as the Qin ancestral-temple setting where 嬴政 / 秦始皇 stays for his crown ceremony in 238 BCE. The episode explains the rite as the transition into adulthood and personal rule.
Yongcheng also becomes the crisis geography for the 嫪毐 rebellion and its aftermath. Lao Ai aims at the palace setting there, and after the rebellion is suppressed, Ying Zheng moves 赵姬 to Yongcheng’s Fuyang Palace before 茅焦 persuades him to bring her back to 咸阳.
《资治通鉴·秦纪》121｜嬴政造世界最早高速公路 2200年荒草不生 adds a post-unification ritual role. The episode reads Qin Shi Huang’s first westward departure from 咸阳 through 陇西郡 and 北地郡 as likely movement toward Yongcheng for 高庙礼, a report of imperial achievement to Qin ancestors in the old capital region.
