The mascot is named "Haibao". It takes the Chinese character "ren" (meaning "person") as the core concept. The anthropomorphic Haibao cleverly interprets the theme of the Shanghai World Expo 2010 - "Better City, Better Life". After all, people are the main characters of city life. Meanwhile, "Haibao" also integrates the element of "sea". It is water-like in its main form, with a hairdo styled like sea waves. Its color is chosen as sea blue. Moreover, its name "Haibao" itself implies "the treasure of four seas".
