In the Ly dynasty (1009-1225), the country was divided into a total of 24 “ lo” in addition to “ phu” and “ chau”. A number of administrative divisions under “ lo” such as “ phu” Do Ho and Thai Binh, and “ chau” Ai, Thai Nguyen, Hoan Duong, Thach Ha, Do Luong and Thien Lieu were mentioned in this period.

Yet, under the Early Le dynasty (980-1009), according to “ Dai Viet Su Ky Toan Thu” (The Complete History of the Great Viet), in March 1002, King Le Dai Hanh renamed “ dao” into “ lo”, including “ lo” Bac Giang, Quoc Oai, Hai Dong, Hoan, Ai, Lam Tay, Dai Hoang, Dang, Thai Nguyen and Phong.

Although documents on these 10 specific “ dao” have not yet been found so far, the records about the Dinh and Early Le dynasties have helped guess the names of “ dao” in this period, including Bac Giang, Quoc Oai, Hai Dong, Hoan, Ai, Lam Tay, Dai Hoang, Dang, Thai Nguyen and Phong. Under the Dinh dynasty (968-980), the country was divided into 10 “ dao” (similar to provinces), which, in turn, were divided into “ chau” or “ dong” (districts). The formation of administrative divisions from the Dinh dynasty to Nguyen dynasty witnessed many changes in the ways of division and naming.
