Timeline

1. 1011–1016Dingzhou · HebeiUnder Zhenzong, forts, stockades, and beacon towers were built along the Liao border in Hebei's prefectures, with imperial cavalry and infantry garrisoned. Dingzhou, Zhenxiong, and Xiongzhou formed mutually supporting defensive positions linked by ditches, beacon towers, and stockades against Liao cavalry raids. Works were supervised by transport commissioners with prefectural laborers and soldiers building in sections.
2. 1015–1020Huanzhou · GansuShaanxi border circuits simultaneously reinforced forts against Western Xia; Huanzhou, Qingzhou, and other places repaired old cities, added stockades, and stored grain and weapons. Although Song-Xia relations were generally peaceful under Li Deming, the Song court maintained border works as precaution, making frontier expenditure a regular fiscal item.
