What is the price of Xie's calligraphy works in Henan?

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, they are valuable and worthless, expensive and relatively cheap. The price of a painting and calligraphy will be different in different places, different times and different auctioneers. So it's hard to judge.
