福寿沟,一条修建于北宋时期的下水道直至今日依然承载着一座城市近10万老城区居民的排污、防涝和抗洪功能。东依贡水,西傍章江的江西赣州历史上曾常年饱受水患,居民苦不堪言。为使古城免遭内涝之灾,福寿沟应运而生。2016年8月,国务院总理李克强在考察福寿沟时,称赞其为造福百姓、延寿千秋的城市良心工程。那么,究竟是谁主持修建了这套精密而成熟的古代排水系统?是刘彝,千年之前北宋时期的一个普通官员。 Fu Shou ditch, a sewer constructed in the Northern Song Dynasty, still bears the sewage, waterlogging and flood fighting functions of nearly 100,000 old urban residents in an urban city today. East according to tribute water, west of Zhangjiang Jiangxi Ganzhou had suffered perennial floods in history, residents miserable. To make the ancient city from waterlogging disaster, Fushou ditch came into being. In August 2016, Li Keqiang, premier of the State Council, praised it as an urban conscience project that benefits the common people and prolongs their lives. So who exactly presided over the construction of this sophisticated and mature ancient drainage system? It was Liu Yi, a common official of the Northern Song Dynasty a thousand years ago.
