I just learned today: Why can't two identical words in calligraphy appear at the same time?
When writing two identical words in Chinese calligraphy at the same time, why should the following word be replaced by a word that looks like 2?
That's an ellipsis. Calligraphy pays attention to beauty. In a word, pay attention to "swallows don't fly together" (the wave painting in official script can't appear twice at the same time). In a work, we should also try to avoid the repetition of a glyph. The purpose is to reduce similarities, enrich changes and increase aesthetic feeling.
