The market has the final say on price, some buy high-end products and some buy low-end products. In addition, the prices of the same and different calligraphy and paintings are different in the eyes of different people, but no matter who has good or bad calligraphy and painting, some are valuable and some are not valuable, some are expensive and some are relatively cheap, so it cannot be generalized. In terms of square feet, we can only say how much a square foot costs for a certain piece.
Runge has no accuracy, it is just a reference. It mainly depends on your own judgment and understanding of his calligraphy and painting, as well as the market hype at the time. A calligraphy and painting will have different prices in different places, at different times, and in the hands of different auctioneers. For example, some paintings and calligraphy by the same person are worth 1,000 yuan/square foot, some are worth 2,000 yuan/square foot, and some may be worth 3,000 yuan/square foot,..., or even 10,000 or tens of thousands/square foot... ····; And changing to another auctioneer or intermediary is a different situation...so it is difficult to judge, and there is no absolute price.
