Wang Zhenfan's calligraphy value per square foot

unless you know it, and it's a specific one. Because no matter who's calligraphy is good or bad, there are valuable and worthless, expensive and relatively cheap, so we can't talk about it in square feet, we can only say how much a piece is. Runge has no definite aim, but is just a reference, which mainly depends on his own judgment and understanding of his paintings and calligraphy, as well as the speculation in the market at that time. At the same time, the price of celebrities is higher than that of ordinary people. As long as it's okay, it's collectible. My own opinion, please forgive me for being wrong!
