逝者如斯夫，不舍昼夜。运河的流水千年间昼夜不止，河上与河边人的生活经历了翻天覆地的变化。曾经通州运河上首尾相接的漕船，嚎唱着劳动号子的船夫早已不见踪影。货船变游船，村落变高楼，运河号子作为一种文艺表演被留存下来。

Introduction:Time and water go by forever, day and night. The canal flows day and night for thousands of years, and the lives of people on and near the river have undergone earth-shaking changes. Once on the Tongzhou Canal on the end of the cao ships, howling singing the work of the boatman has disappeared. Cargo ships turned into cruise ships, villages turned into high-rise buildings, and canal numbers were preserved as a kind of artistic performance.
