How much is the value of a pair of 4 square feet in Yuan Min's calligraphy? It was written in 1991.

However, the market has to decide whether the price of artworks is high or low. Some people buy high-grade artworks and some buy low-grade artworks. In addition, the prices of the same and different calligraphy and paintings are different in different people's eyes, but no matter who's calligraphy and paintings are good or bad, there are valuable and worthless, expensive and relatively cheap, so we can't generally talk about square feet, we can only say how much a piece is. Runge has no definite aim, but is just a reference, which mainly depends on his own judgment and understanding of his paintings and calligraphy, as well as the speculation in the market at that time. The price of a calligraphy and painting will be different in different places, different times and different auctioneers. For example, some paintings and calligraphy of the same person are worth a level in 1 yuan or 2 yuan, some are worth a level in 5 yuan or 1 yuan, some are worth 1 yuan/level, some are 2 yuan level, some may be 3 level, or even 1, or tens of thousands level; Moreover, it is a different situation to change to another auctioneer or intermediary, so it is difficult to judge, and it is not an absolute price. Any individual's evaluation is only one-sided and personal. Characteristic, celebrity, and favorite buyers want it, which may make the price higher. However, if the price of painting and calligraphy is high only because someone has a job now, or simply because of hype; Then when he retires, or no one speculates, the price will soon come down, even worthless. This is true of any other work of art. As long as it's okay, it's collectible. What's special here is that Runge is an unreliable reference, mainly depending on the market and my own understanding of the works, as I said above. There are also imitations, printed matter and line paintings that are worthless, except for long-standing celebrity works and celebrity imitations that are worth some money. Sorry, you still have to take your own ideas. What others say can only be used as reference. My own opinion, please forgive me for being wrong.
