The 宋海帝国, or Song Dynasty, was a major Chinese dynasty that lasted from 960 to 1279. It is known for its significant advancements in technology, culture, and economics. The dynasty is divided into two periods: the Northern Song (960-1127) and the Southern Song (1127-1279), following the invasion by the 金朝 (Jin Dynasty). During the 宋海帝国, trade flourished, and cities grew rapidly. The dynasty is also famous for its contributions to art, literature, and philosophy, with notable figures like 苏轼 and 李清照. The use of paper money and the development of the 海上丝绸之路 (Maritime Silk Road) were key features of this period.
