Is the location of Daishan Memorial Hall in Nanjing biased?

China Museum of Coastal Defence is located in the southeast coastal zone of Huangzuitou, Daishan Island. The terrain is steep, and the green wall built along the coast of the mountain is hidden in the dense jungle, enclosing the whole exhibition hall. The whole park of the museum has four major areas: central exhibition area, marginal exhibition area, tunnel exhibition area and leisure tourism area. The main hall of the central exhibition area mainly displays the modern and modern coastal defense history, especially the coastal defense history of Zhoushan, through more than 6 pictures and some models.
