Black dialogue, inside and outside. From high to low, from coarse to fine.
From far to near, from ancient times to the present. From dawn to dusk, from morning till night.
There is right and wrong, there is in and out. Width and narrowness, buying and selling.
From south to north, head to tail. From west to east, from beginning to end.
Dry to wet, public to private. Beauty is ugly, and thinness is thick.
Salt to light, sweet to sweet. Heaven and earth, thick and thin.
