沙丘 / Shaqiu
沙丘 / Shaqiu enters this ingest through Qinji 135 番外篇1 as the place where 秦始皇 dies after 许负 refuses his summons and predicts Qin’s collapse. In this source, the place functions as the payoff to the fate-reading branch: avoiding a meeting with the emperor becomes understandable once his death at Shaqiu confirms the danger of the late-Qin court.
This page is a place node, not the event node 沙丘之变. The older Shaqiu Crisis branch belongs to 赵武灵王 and Zhao succession politics; the Qinji 135 branch uses Shaqiu as the late-Qin death-site reference.
