Culture Architecture There are a large number of German-style buildings in Qingdao's city center, a remarkable fact considering the German leased-territory period only lasted 16 years (1898–1914). The unique combination of German and Chinese architecture therein, combined with German demographic roots and a large Korean expatriate population, gives Qingdao a rather distinct atmosphere. An old saying described Qingdao as a city of "red tiles green trees, blue sky, and blue sea." This saying indeed gives a picture of a bird view of Qingdao. A larger number of areas in former foreign styles are well preserved. Although the new city area is under large-scale reconstruction, the old city area (especially the western part of Shinan District) still retains many traditional buildings.
