The Blue Dragon, chosen as a title for this story, is the national emblem of China, adopted as such by a desire to flatter and propitiate that spirit of evil considered to be the most powerful. As the dragon is believed to be big enough and strong enough to overcome and devour all the other wicked genii who continually vex Chinese life, the wise men of the "Black-haired People" thought it best to have him on their side, and consequently accorded him the highest honor in their power to bestow. As we of America chose the eagle, strongest of visible air spirits, for our national emblem, so the Chinese chose the most powerful of invisible spirits in whose existence they believe as firmly as we do in the existence of things that we can see, hear, or feel.
