Yujin Sanga is a shopping complex along Hongjecheon in Hongje 3-dong, Seodaemun-gu, Seoul, where fruit, dried seafood, clothing, and household goods are sold. Samsung Electronics, a jewelry shop, Lotte Super, and restaurants are all located in the same building. Built in 1970, the complex carries more than 50 years of age in its structure. When the Naebu Expressway overpass was built, sections of the fourth and fifth floors of Building B were demolished, so the original left-right symmetry no longer remains.
