In the past, rarely could a charming high-class lady of a famous person's calligraphy be seen. Things that were 'miraculous' have lost their meaning and their dazzle.

People have similar values and similar ways of thinking.
In the end, all our faces will become the same colour with the same noses, eyes and mouths. However, inside each window, a few differences should remain, even if only minute.
