The tourism logo is in a square shape with round corners, resembling a seal. The round design comes from the English letter "Q" in capital; the three wave shaped lines stand for Qingdao's status as a tourist city, a seaside city and a harbor city; the corresponding wave-shaped lines on Qingdao strengthen the romantic beauty of the whole design. The main colors of the badge are gold and green because gold has the meaning of brightness and hope, which is the color of sun-rising on the sea, and green, meaning Qing in Chinese, implies the meaning of "Qingdao" (Green Island). Green also symbolizes life, vigor, and the spring.
