Dalian is known as the "oriental acacia city," as its flourishing acacia trees can be seen everywhere, alongside streets, in parks or among courtyards in every household. Every May, when acacias are in full bloom, even the air smells of their fragrance, not to mention the lantern-like beauty of the tree. Because of the acacia, spring has become something significant to Dalian citizens. They usually organize many activities, attracting many tourists as well as local people.
