Qingdao.

Qingdao is located in the North Temperate Zone and has a temperate monsoon climate. The city has a significant maritime climate due to the direct regulation of the marine environment. Qingdao is a coastal hilly city with a high east and low west, and the north and south sides are uplifted and the middle is low. Jiaozhou Bay has been an important port in the north since the Tang and Song Dynasties. In 1891, the garrison was established in Jiaoao. In 1897, Germany leased and built ports and railways, and it prospered because of "one port and one road". In 1930, it was renamed Qingdao. After the liberation of Qingdao, it was changed to a provincial city in Shandong Province.
