How much is the calligraphy and painting of Dong Yuncheng, a calligrapher in Juxian County? Do any friends know? thank you

Dong Yuncheng's calligraphy works are household names in Juxian County. Although he is a member of Shandong Calligraphy Association, he has a profound knowledge of calligraphy, which is not comparable to that of ordinary China Calligraphy Association members. He may be a little old and doesn't care much about some titles. As for the price, there is no specific standard. The key is your love and appreciation of calligraphy.
