However, the price of works of art is determined by the market, some buy high-grade and some buy low-grade. In addition, the same and different calligraphy and paintings have different prices in different people's eyes, but no matter whose calligraphy and paintings are good or bad, there are valuable and worthless, expensive and relatively cheap, so we can't talk about the square in general, we can only say how much a painting costs.
Mainly depends on the judgment and understanding of calligraphy and painting, as well as the hype in the market at that time. The price of a painting and calligraphy will be different in different places, different times and different auctioneers.
The paintings and calligraphy of the same person have a value of 10 yuan or 20 yuan square, a value of 100 yuan per square 50 yuan, a value of 1000 yuan per square, a value of 2,000 yuan per square, a value of 3,000 square, or even1000 million or tens of thousands of square meters.
Expanding information and changing to another auctioneer or intermediary is another situation, which is difficult to judge and not absolute price. Any personal evaluation is only one-sided and personal. Unique, celebrity and favorite buyers all want it, which may make the price higher.
However, if the price of calligraphy and painting is high just because someone has a job now, or simply because of hype; Then when he retires, or no one is speculating, the price will soon come down, even worthless. The same is true of any other works of art, as long as there is no problem, they are all collectible.
Mainly depends on the market and my own understanding of the work, as mentioned above. Imitations, printed matter and line drawings are all worthless, except those famous works and celebrity imitations for a long time.
