How much is Ji Minyong's six-foot calligraphy worth?

There is no uniform standard price for the works of any calligrapher or painter. Because each painter's works and paintings have different levels, of course, the price of each painting is naturally different. Every painter's works are big and small, beautiful and ugly, good and bad, fine and bad, and the transaction price of each painting and calligraphy by each painter is different.
