It is well known that there is a lack of basic historical materials in the study of the military system in the Song Dynasty,especially in the Northern Song Dynasty.The tower of Kaiyuan temple in Dingzhou,built in the fourth year of Xianping in the Northern Song Dynasty, keeps many inscriptions of the tower repairs which can make up for the deficiency in this aspect. Based on these stone carvings,and combined with relevant research and documentary records, this paper sorts out the military officers under the Zhihui(Battalion)of the Northern Song Dynasty.Some problems have not been studied in the academic field, such as the specific meaning,classification,setting of different arms,ranking of positions,etc.According to their nature,these officials can be divided into two categories.One is the dispatch system.Among them,those who are in charge of the battle are the Yuanliao,Juntou,Shijian,Jiangyuhou, Chengju and Yaguan. The Tongyinguan and Caosi were the officers in charge of the administration.The other is a class of titles expressing honor and rank,such as the Puye, Shangshu,Dianshi.The existence of Shangshu,Puye and other titles indicates that the j unior military officer system of the Northern Song Dynasty has the characteristics of the former military system.In the establishment of Du,except for those who have been proved to be clear in the academic circle,such as Junshi,Fubingmashi,and Dutou,Fudutou,there are also Yuanliao, Juntou,Shijiang,Jiangyuhou,Chengju and Yaguan.Among them,they are in one rank for Yaguan and Chengju,one rank for the general of Jiangyuhou and Shijiang for the general,and one rank for the Fubingmashi and Junshi and for the general.A military officer of Yuanliao is below the Du level.Jieji refers to the general or general term of the lower rank officers such as Juntou,Shijiang,Jiangyuhou,Chengju andYaguan.Jieji is generally under Du,and each Du has several sections, thus confirming and supplementing the existing research conclusions. According to the specific situation,Yuanliao is not only set up in Imperial Guard,but also in the Militiaman.It is believed that Yuanliao in the Militiaman should be a real position,and is a general name of a certain level of officers,not a specific military officer name.The Juntou is set up below the Du of the Imperial Guard and the Du of the Xiang army.One head of the army is set up in each Du.Shijiang has been set under Du,and included no less than three people.The Jiangyuhou is not only set up in the Imperial Guard and Xiang army,but also in the Militiaman. As far as the setting up of Xiang army in Hebei Road is concerned,it is common to place Jiangyuhou under the command of Xiang army.The Chengju is set up under Du,and has left and right divisions.The number of employees in each Du may be at least four.Yaguan is set in the Imperial Guard,Xiang army and the Militiaman.In the Militiaman one officer has twenty-five men. The Tongyinguan and Caosi should be set up in the j unior military system,borrowing the name of administrative officials but serving the military.Judging from the inscription,the number ofJianjiao-shangshu is quite large.Dianshi is set under the Du.
