Some people say that painting with calligraphy skills will be good. Is it true?/You don't say.

"A short slip makes a long regret" calligraphy requires a very high pen, and calligraphy pays attention to strokes! There is no room for revision! There is relatively room for slight modification in painting! Learning calligraphy well will get twice the result with half the effort! People with calligraphy skills will understand it well when they learn to draw!
