The price of Bao Guoan's calligraphy works

No matter whose handwriting is good or not, there are valuable and worthless, expensive and relatively cheap, so we can't say in square terms, we can only say how many squares a piece is. 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. My own opinion, please forgive my mistake!
