The antique documents and the old books handed down since the late Chosun Period are collected in the house of Kim, Ki-Hong. To classify them into certain types, old documents (243 sheets of 174 pieces) are biography, household registers, kings" order papers, Kim, Heui-Jeong s own poetry and prose, a congratulatory poem for ones 60th birthday; and ancient books (4,514 sheets of 40pieces) are a collection of literary works and journal by Kim, Heui-Jeong, all sorts of materials for the preparation for Guageo (the civil service examination) and books related to oriental medicine. Their production years is thought to be mostly from 1758 to 1930s and only 9 pieces are those after 1950s.
Although these materials have been passed down and housed over 8 generations of Kim, Ki-Hong"s ancestors, a considerable number of them were produced, acquired or collected by Kim, Heui-Jeong, the great grandfather of Kim, Ki-Hong (1844~19l6), not a little was added by Kim, Heui-Jeong"s sons, Hang-You (1874~1908) and Hang-Gak (1876ㅡ1946)，and also his grandson, Pil-Won (1900?1950). For such an accumulation of collection, not only his family"s background but also his academic devotion and the consequential socio-political status played a great role.
From these materials, it is revealed that Kim, Heui-Jeong"s pedigree belonged to an influential class in the country village of Jocheon-ri as petty functionaries since the late 18th century and in this relation, his family led his village. Also, since his presence, successful candidates for Kuageo, the classical examination system for the government service in old time, came out from his lineage and advanced to the offices of the central government, while, vigorously making mutual exchanges of opinions with the masters in the central Confucian circle, thereby securing his firm position as members of confucian scholars, accepted as the Jejus representative Confucians in both the national and local confucian circles.
In addition, through a review of these, one can get a sense of the change in the caste system, corvee labor and the practices and the procedures over the economic transactions such as trades of land and slaves. In particular, one can get a taste of the ways to prepare for the government examination system and the style of writing qualifying for the government examination system respected by the Confucian scholars in the late Chosun period. Meanwhile, leading figures in the Confucian circle in the Jeju society from the late 19th century to the early 20th century and their social network can be clearly seen from them. Besides, an aspect of the conflicts between Chosun and Japan over Jeju region can be grasped from here.
