The fineness, age and technology of jade are all factors that determine its value. The standards of calligraphy, painting and Wan Wen are similar to those of jade. We often see a calligraphy and painting being successfully auctioned at a sky-high price. In fact, if you only look at a calligraphy and painting from a physical point of view, it is nothing more than a piece of paper and some pigments or ink. But the criteria for judging the value of painting and calligraphy are not only the quality of paper or ink pigments, but also the level of painting and calligraphy works, the production age of painting and calligraphy and the name of the author.
So calligraphy and painting are expensive because it is artistic and irreplaceable. Does an artist need to practice polishing skills for a long time to be an artist? Home? Yes It is difficult to measure this decades-long effort with a unified standard. A piece of gold can be exchanged for another piece of gold with the same weight, just like industrial products produced by assembly line machines in factories, all of which have the same price, can be copied countless times and can be replaced indefinitely.
Calligraphy and painting works are all created by people themselves. Once they are manufactured, there is no possibility of being replaced. Even calligraphers or painters can't draw exactly the same two works. In a painting and calligraphy work, the skill displayed by the author, the connotation of the work and the year of the work are incalculable.
