Dui, serenity, southeast, white and grey, metal, reflecting surfaces. The lake. Water is referred to in two of the chapters. If you look at it from a pier or from a boat, it looks black. But if you see the surface in a landscape, it shines and reflects. Plants and trees appear as silhouettes, insects dance as black dots over it. Also facades with many windows have this reflecting surface and thus belonge to the same symbol group. And this is the plan. The colors seem to be chosen roughly, but I cannot change the plan, it is part of Chinese medicine and oracles. Just the idea about "all" is my own.
