Even if the transaction price of a work is known, it cannot represent the price of all works. Because no matter whose handwriting is good or not, there are valuable and worthless, expensive and relatively cheap, so we can't say how much money in general. 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. At the same time, the price of celebrities is higher than that of ordinary people. As long as there is no problem, it is collectible. My own opinion, please forgive my mistake!
