Daeseong Seojeom is a bookstore at the entrances of Gwangyang Rotary and Daehak-ro in Jeju City. Staff locate the book you are looking for, and if another bookstore does not have it, they order it directly from the mainland. The store is small in appearance but holds a large number of books. It sits in an area with the Jeju City Hall, Venture Building, and financial institutions, so office workers and residents also come here.
