The first two divinatory symbols of the sixty-four divinatory symbols in today's "Yi-ching" are the "Chain" and "Kuen", and the last two are the "Ji-Ji" and "Wei-Ji". The connection of the beginning and the end indicates a process of the universal constructing. As the beginning, "Chain" and "Kuen" represent the basis and start of everything in the world. As the ending, "Ji-Ji" and "Wei-Ji" represent the infinite of everything in the world. "Ji-Ji" followed by "Wei-Ji", indicates the changing in the universe is endless. So the arrangement from "Chain" ''Kuen'' to "Ji-Ji" "Wei-Ji" doesn't only mean the order of the divinatory symbols, but also represents the process of the the universal constructing and indicates the endless process in the universe.
