[红灯笼]唐宋大运河的繁荣（续）
北宋定都汴京（今河南开封），沿用了隋朝的运河体系。隋炀帝开凿的通济渠是支撑开封物资需求的重要运输干线，在宋代被称为“汴河”。这条运河的前身是战国时期魏惠王开凿的鸿沟。北宋将这条运河视为国家的生命线。当时的汴河得到了精心的维护，全河水位均衡，水势平缓。

[红灯笼]Prosperity of the Grand Canal in the Tang and Song Dynasties（To be continued）
The Northern Song Dynasty chose Bianjing (today's Kaifeng in Henan Province) as its capital and retained the canal system from the Sui Dynasty. The Tongji Canal, excavated by Emperor Yang of Sui, was the transportation artery supporting the needs of Kaifeng and was called the "Bianhe Canal" in the Song Dynasty. The predecessor of this canal was the Honggou Canal, excavated by King Hui of Wei during the Warring States Period. The Northern Song Dynasty regarded this canal as the lifeline of the country. The Bianhe Canal at that time was carefully maintained, with a well-proportioned water level and gentle water flow throughout.
