The reform initiated by Khuc Hao was the first reform in the history of Vietnam carried out in the context that the country had just gained autonomy from the Duong Dynasty (China). With the positive contents of the reform program, it has made many important contributions to the solid construction of the nation's autonomous government after a period of arduous struggle. Accordingly, the land issue has had certain adjustments compared to the Chinese domination period, which has had a strong impact on the economic and social changes of the country. The paper focuses on studying the basic issues of land ownership in Khuc Hao's reform program, through which it outlines the basic characteristics of Vietnam's land ownership in the early days of gaining autonomy. The research results will contribute to adding useful references on land issues in the history of the Vietnamese nation in the early 10th century.
