Haunted House of Cheonggyecheon

The entry 'Haunted House of Cheonggyecheon' appears in the research target but is not substantiated by the provided sources. The materials reviewed include a biographical page for cinematographer Hong Kyung-pyo (Alex Hong) and an urban design timeline diagram that references the Cheonggyecheon Stream in a planning context. Neither source identifies a specific building, provides coordinates, records historical information about a haunted house, documents witness accounts, nor describes any paranormal phenomena tied to a structure near Cheonggyecheon. Because the name links the alleged site to Cheonggyecheon, the stream itself is mentioned in one source as part of urban-design discourse; this reference does not connect the stream to supernatural activity or to a house. No entities, theories, or investigative findings relating to a haunted house at Cheonggyecheon are present in the supplied material. The existence, location, and nature of any such haunted house therefore remain unverified based on the provided documents.
