The household register of Yeongi-gun, Chungcheongnam-do Province, created in 1904, missed many populations like that of the Joseon Dynasty. The land registry of Yeongi-gun created in 1900 reflected the characteristics of the duty policy of the Joseon Dynasty in detail. That land register in the Great Han Empire period had faithfully inherited the tradition could be predicted to some degree by a study of the new household register. It is very unlikely that among the population census and the land survey that were conducted during the same period, only one is traditional and the other is modern. What the people in the Great Han Empire period were thinking of can be guessed through a comparison of the household and land registers of Yeongi-gun. They thought that there was no need to connect the household register with the land register. The connectivity between the household register and the land register was even lower in the Great Han Empire period than in the 1720s. Why did this phenomenon happen? It seems to have been influenced by Neo-Confucianism. Zhu Xi thought that all creatures have their own unique reason. That thought can be considered as emphasizing the uniqueness of all creatures. The Great Han Empire bureaucrats, who were immersed in Neo- Confucianism, may have thought that it was natural not to connect the household register with the land register because both of them had their own unique reason. This does not mean, however, that the two books were not connected because of Neo-Confucianism. That is, the people of the Joseon Dynasty did not think that the household register and the land register should be necessarily connected. In the 1720s, the household register was not completely connected with the land register, either.
