There are some ancient and magical legends about the origin of mathematics. Legend has it that in very, very distant ancient times, one day, a "dragon horse" suddenly jumped out of the waves of the Yellow River. On the back of the horse, there is a picture with many mysterious mathematical symbols painted on it. Later, a "god turtle" climbed out of the calm waterinfo, with a book on its back, which explained the arrangement of numbers. The picture on horseback is called River Map, and the book on turtle's back is called Luo Shu. Mathematics was born as soon as the Book of Hutuluo appeared.
