Everyone's paintings and calligraphy are good and bad, valuable and valuable, expensive and relatively cheap, so you can't say in square terms, you can only say how much a piece 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. So it is difficult to judge, and it is not an absolute price; Besides, any personal evaluation is only one-sided and personal. Close-ups, celebrities and people who especially like them 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. Sorry, that's all I can say. Still have to make up your mind. What others say can only be used as a reference. My own opinion, please forgive my mistake.
