《新序》 / Xin Xu
《新序》 / Xin Xu enters the wiki through 《资治通鉴·秦纪》119-2｜咱们都冤枉了背负2000多年黑锅的“叶公好龙” as the 刘向-compiled Western Han story collection that preserves the 叶公好龙 anecdote. The episode describes the work as drawing on transmitted stories from Zhou through Western Han and using them to promote humane governance.
In this ingest, Xin Xu matters as a source layer rather than as a neutral container of fact. The host treats the Ye Gong story as a moralizing anecdote whose later idiom life damaged 叶公’s reputation, so the page belongs with the wiki’s source-critical treatment of memorable but suspect origin stories.
