Han Dekun has a profound foundation in the field of calligraphy. He loved calligraphy since childhood, systematically studied calligraphy theory in military life, absorbed the essence of ancient and modern calligraphy, and combined with his own understanding, formed a unique calligraphy style. His works have been included in large-scale albums such as "Collection of Paintings and Calligraphy of China Diplomats" and exhibited in many exhibitions.
However, it should be noted that the collection and evaluation of calligraphy works is a relatively complicated process, which requires comprehensive consideration of multiple factors. In addition to the artistic value of the work, it also includes the author's popularity, the historical background of the work, the preservation state and many other factors. So if you want to know the specific value of Han Dekun's calligraphy, I suggest consulting a professional calligraphy art critic or an art appraisal agency.
