Qingdao, a German concession taken in 1897 and ceded for a total of 99 years, retains much of its colonial architecture and charm. The city has changed hands many times since then. The Japanese took the port in 1914, formerly ceded to them by the Treaty of Versailles in 1921. The city was returned to China in 1922 and in 1938, it was then taken back by the Japanese and finally returned to China during World War II, 1945. However, the dislocations of these changes have left little mark upon the city proper. The German influence in Qingdao extends beyond impressive architecture to many other areas; from town planning, creating lush wooded avenues and some of China's best parks, to local customs.
