Ancient calligraphers did not say black cloth, but white cloth, which meant that when writing, attention should be paid to the connection between words and lines, that is, the composition of calligraphy works, so that the works written in this way are black and white and natural and harmonious. This is white cloth. Cloth means spread out. It depends on how a writer arranges the gaps in the text, and these gaps are in contrast and correlation with the black handwriting.
