I have a picture of Zhang Shaozhou's calligraphy and painting: Flying Dragon in Heaven: How much can it be worth?

Zhang Shaozhou, born in 1954, is of scholarly family. My ancestral home is Luoyang, Henan Province. Member of China Calligraphy Association, a famous calligrapher with strong strength. He is currently the vice president of China International Painting and Calligraphy Institute, the art consultant of China Communication University, and the special calligraphy consultant of China Electric Power Bidding and Purchasing Network. He lives in Beijing now. As a modern painter's work, Zhang Shaozhou's paintings are works of art, but not antiques. If it is genuine, it depends on how many square feet there are and the quality of the painting. The market price is about 5,000-8,000/sq. ft., of course, it refers to fine products.
