Pei Taiping's calligraphy price per square foot

No matter whose paintings and calligraphy are good or bad, there are valuable and worthless, expensive and relatively cheap, so generally we can't talk about it in square feet, we can only say how much it costs per square foot. 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. If you are a celebrity, you may have higher value. If you are not a celebrity, it depends on the quality of calligraphy and painting, whether there are features and so on. And you can't generalize. My own opinion, please forgive my mistake!
