Do you accept Dong's calligraphy and painting?

Dong's calligraphy and painting are collected here. Is Dong's calligraphy worth 3,000-5,000 yuan per square foot? . Dong, born in 1964, was born in Wen 'an, Hebei. I like calligraphy since I was a child. I studied under Wang Baocheng and graduated from Haidian University for the Aged. He is currently a member of Hebei Maoti Calligraphy Association, an academician of Beijing Huaxia Lanting Painting and Calligraphy Institute, a member of China Contemporary Artists Research Association of the Folk Cultural Relics and Arts Chamber of Commerce of the All-China Federation of Industry and Commerce, and a member of Langfang Hard Pen Calligraphy Association of Hebei Province.
