Introduction to the second floor of Xinhai Plaza: The architectural design of Xinhai Plaza is creatively implemented by the Australian Porto Group, one of the five largest design companies in the world. The exterior of the square adopts an 88-meter streamlined glass curtain wall, which fully demonstrates the post-modernist characteristics of the building; the interior of the mall adopts a simple European architectural style, focusing on the smoothness and layering of the shape. On the second-floor platform of Xinhai Plaza, there is the largest sea view platform among Qingdao’s commercial complexes, allowing visitors to enjoy the endless charm of Qingdao’s coastline at a 270° angle.
