The purpose of this study is to approach the organization and activity of a group called Jaegyeong Yulgokmyeon Hyangwuhui (a friendship group of people who are from the same hometown) in a township unit as a research case from the perspective of "hometown." In detail, the study is to find out how people who left their hometown and moved to Seoul as the city of their main livelihood have organized, operated, and communicated in interchanges and against which background. Meanwhile, the study intends to review their thoughts about their hometown, the kind of activities their hyangwuhui has performed for the advancement of their hometown, and what are the expectations of local residents who reside in the hometown and social organizations of people who left their hometowns from an anthropological perspective. The results include the following. The Jaegyeong Yulgokmyeon Hyangwuhui mentioned in this study was established in 1983. The founding of this organization did not stem from the need for a psychological exit through which people who left their hometown desired to be freed from any sense of alienation, loneliness, or complexes that they had felt in urban life. That is, the need for establishing a hyangwuhui was proposed as some figures from a specific hometown became representatives of their region and country, and, meanwhile, such hyangwuhui was founded centering on school ties, namely an alumni reunion. The interpersonal combination of members is not continued only by any thought about the villages from which they come or the hometown of each individual. The hyangwuhui can be a sustainable meeting only when the vertical relationship between juniors and seniors in age from the same hometown and the horizontal relationship between alumni is in harmony, and it may be an alumni reunion that provides its foundation. The formation of interpersonal relationships that highly regard the reinforcement of friendship and bonding of a hyangwuhui makes the members feel nostalgia for their hometown even while in a city and functions as a locomotive for the continuation of the meeting. In detail, not only formal meetings such as a regular general assembly or athletic meeting, but also informal meetings including participation in family events and alumni reunions by class year serve to deliver the customary practice of strong attachment in the lifestyle of their hometown to people who left their hometown to live in a city. Also, at the same time, it supports their gathering together; however, such cohesion of a hyangwuhui does not revert to an identity simply by the members being from the same hometown. That is, it can be identified that a hometown that they imagine as persons who left the hometown where they were born and grew up is not a simple conceptual hometown in which the village living of the past is idealized, but it is a field on which they can newly restructure their living and be rooted with their unification. The way of their involvement in hyangwuhui activities for the advancement of their hometown and in personal and social organizations in their hometown for the advancement of the hyangwuhui may be a transformed form of the mutual aid that may be seen in today`s society, although it is not of the same kind in terms of contents. In other words, it may be seen to be for the promotion of friendship between members while everything is converged superficially under the name of "for the advancement of hometown" however, it can be in a strained relationship in which they agree on the principle of mutual benefit in an implicit manner in depth. From the perspective of research history, the organization and activity of the Jaegyeong Yulgokmyeon Hyangwuhui introduced in this paper may offer a view that people who left their hometown are building a new group while maintaining and developing the relationship from the "hometown" even in a city; however, according to the researcher, the link that binds them is not a past memory but various relationships that are formed through opportunities for gathering together, such as diverse meetings or events.
