Dusty exploration is synonymous with history and ocean, which means exploring history. In the word "stone sea", "stone sea" refers to history, and "stone sea" comes from the Book of Changes: it is nothing more than a turtle to explore its hidden, hook its deep and far away, and decide whether the world is good or bad, and become the best in the world. (Interpretation: There is nothing greater than the "yarrow" and "tortoise shell" used in divination, to explore complex images, to seek mysterious things, to seek far-reaching Taoism, to make people have a far-reaching future, to determine the good or bad luck of the world, and to achieve the diligent work of the world. )
