Shanghai has always been known as the Pearl of the East. The background colour is black, which not only expresses that Shanghai is a city that never sleeps but also highlights the element of white. At the same time, the red that can represent China is selected to outline a circle, which also shows the importance of Shanghai to China. Inside is the combination of the Shanghai flower Magnolia and pearl. In order to make the logo design less monotonous and common, coupled with the button design of Shanghai's traditional dress cheongsam, the background not only represents the night but also can be regarded as a part of the cheongsam.
