However, the price of artworks is determined by the market, some buy high-end products and some buy low-end products. 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. Long Ge has no clear purpose, but only a reference, mainly depending on his own judgment and understanding of his paintings and calligraphy, 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. For example, the paintings and calligraphy of the same person are worth 10 yuan or 20 yuan square, 100 yuan square, 1000 yuan square, 2,000 yuan square, 3,000 square, or even1000 million or tens of thousands. Moreover, changing to another auctioneer or intermediary is another situation, which is not easy to judge and is not an 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. What is special here is that Runge is an unreliable reference, mainly depending on the market and my own understanding of the work, as I said above. There are also imitations, printed matter and line drawings that are worthless. Besides the famous works with a long history, celebrity imitations are worth a little money. I'm sorry, but I still have to make up my mind. What others say can only be used as a reference. My own opinion, please forgive my mistake.
