The market has the final say on the price level, some buy high-end products and some buy low-end products. In addition, the same and different calligraphy and paintings have different prices in different people's eyes, but no matter whose calligraphy and paintings are good or bad, there are valuable and worthless, expensive and relatively cheap, so we can't talk about the square in general, we can only say how much a painting costs. His works have no specific price now, but they are collectible!
