Introduction to the used book market: There are many used bookstores on the first floor of Dongdaemun Peace Market. The used book street has become another shopping attraction in Dongdaemun in the past 30 years. In the small second-hand bookstore built along the Cheonggyecheon Stream, you can often see customers burying themselves in piles of used books as high as a person and searching for treasures. We sell everything from old novels, essays, poetry collections to new books, various professional books, foreign books, and rare books, and the prices are about 30-40% lower than the market price.
