海河

海河水系汇华北诸流北入渤海，塑造京津一带的现代河流故事：运河、港口与城市排水，把「北方」写成沿海的、可治理的水网。

The Hai system gathers north-China streams toward the Bohai, shaping Beijing and Tianjin’s modern water story—canals, ports, and urban drainage writing the north as a coastal, managed network.

与黄河摇篮叙事互补：华北也有入海之河。读海河，是读都城与口岸如何共享同一套治水与航运记忆。

Complements Yellow River cradle narrative: north China also has a sea-bound river. Capitals and ports share one memory of control and shipping.
