relocation of Chinese dwellers along the coast. With the completion of such series of mass construction projects such as wharves, the Tsingtao-Jinan Railway Line, Tsingtao Railway Station and locomotive works, a city was starting to take shape. The area had the highest school density and highest per capita student enrollment in all of China, with primary, secondary and vocational schools funded by the Berlin treasury as well as Protestant and Roman Catholic missions. In 1910, the Germans drew up for the second time the city planning of Tsingtao (Warner 2001, p. 33). The former urban area was extended four times highlighted by the emphasis on the development of commerce and trade. Sun Yat-sen (1866–1925), leader of the Chinese Revolution of 1911 and subsequently first president of the Republic of China, visited the Tsingtau area and stated in 1912, "I am impressed. The city is a true model for China's future". 1914–1922 The development of Tsingtao urban space continued during the first Japan-occupation period (1914–1922). In 1914, Tsingtao was taken over by the Japanese and served as a base for the exploitation of natural resources of Shandong and northern China. With the development of industry and commerce, a "New City District" was established to furnish the Japanese colonists with commercial sections and living quarters, which suggested a striking contrast to the shabby houses in the local Chinese zones (Li 2007, p. 133). In the meantime, several schools, hospitals, and public buildings were constructed, followed by urban streets and intercity highways as well. The urban spatial layout continued to expand northward along the east bay area. 1922–1938 The development of Tsingtao urban space during the ROC-ruled period (1922–1938). This period saw the substantial progress of the urban development of Tsingtao. The government engaged itself in mass construction that gave birth to villa districts at the beach and bank groups in CBD. Plenty of public buildings and facilities for entertainment and sports were completed. By the year 1937, the urban population numbered 385,000(Lu 2001, p. 327). Tsingtao consequently distinguished itself as a prominent holiday resort and summer retreat. 1938–1945 The development of Tsingtao urban space during the second Japan-occupied period (1938–1945). Japanese armed forces returned to Tsingtao in 1938 and started to strive for the construction of the Greater Tsingtao in the following June. Accordingly, they worked out the city planning of the Greater Tsingtao and the City Planning of the Mother Town
