Why this record matters
A short description can identify a subject without explaining its stakes. For “Siyuan Pass”, the useful work is to connect “mountain pass in Yilan County, Taiwan” to the records capable of establishing context and consequence.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jul 3, 2026. The linked authority identifier is Q11072598. Authority coordinates are 24.396, 121.356. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
