About
About Sui Xingjin (Xing Jin) Canal — Zhengzhou Segment
Best-preserved western reach of the Sui Grand Canal (Tongji Canal) excavated 605 CE under Emperor Yang of Sui, linking Luoyang to Kaifeng via Zhengzhou. The Xingjin segment near Xingyang shows the 40-m wide canal prism with rammed-earthen banks 4 m high, Song–Yuan wharf revetments in brick, and the Huiluo Barn granary transfer harbour. Sui conscripted 1 million labourers per Sui Shu; the 12-km Xingjin excavated reach retains water and 7-m stratigraphy exposing Sui rammed layer, Tang brick patch, and Ming dredge spoil, making it the Grand Canal archaeological type section. UNESCO Grand Canal element 1443-02 Tongji with Tang-period bridge pier reuse.
Why it mattersType section for Grand Canal stratigraphy documenting 1400-year maintenance and north–south imperial economy.
