After World War II, vernacular architecture appeared in Northern Europe. Aalto of Finland is considered as a representative of the Nordic region. Aalto believes that "the task of architects is to give life to structures". It is emphasized that architecture should have a real human flavor, and architecture should follow regional and national characteristics. For example, his masterpieces between the two world wars were the Newburgh Municipal Library and the Pameo Long Sanatorium. In the early 1940s, he designed the main building in the center of the town of Shannat Ciro. Since the mid-1950s, Japan has also made many attempts to explore its own territory, many of which have certain national traditional characteristics. For example, the design of the Kagawa Hall in Jianshan, Danxia, absorbed the factors of local Japanese folk architecture and embodied the local tendency.
