The same and different calligraphy have different prices in different people's eyes, but no matter whose calligraphy is good or bad, there are valuable and worthless, expensive and relatively cheap, so we can't generally say whose calligraphy is valuable, mainly by our own judgment and understanding of his calligraphy and 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.
