Calligraphy is written on paper and on boards, generally according to the needs of the environment. Writing and collection have different values. Such as building plaques, colonnades, screens made of noble wood, furniture, etc., the words of famous calligraphers are carved on the boards, which has high appreciation value and collection value.
