900-year-old Sewer Still in UseA recent guided tour of historic Ganzhou in east China's Jiangxi Province led sightseers to one of the city's more unusual scenic spots: a 900-year-old sewer still in use.The sewer, built during the Northern Song Dynasty (960-1127), now serves 300,000 residents in the city. It lies about two meters below ground and covers three square kilometers. The ancient drainage system is able to handle heavy rains without backing up, said a local resident, adding that the secret of the system has never been determined. Ganzhou, a well-preserved city of the Song Dynasty (960-1279), has over 300 ancient structures, ruins and scenic spots. It has been called a "museum of the Song Dynasty." |
