Is Mu Yongnian's calligraphy valuable? Can I auction it?

His ancestors have been officials for generations since the reign of Kangxi in the Qing Dynasty, and his grandfather has served in the national government for hundreds of years, which can be described as skillful and pure in family background. Since childhood, Mr Mu Yongnian has been following the instructions of his ancestors. In order to correct calligraphy, I consulted many famous scholars in Shanxi, Hebei, Shandong and Henan, and visited famous scholars such as Liu, Ou, Zhao and Erwang. Because of Mr. Mu Yongnian's integrity and rigorous style, his calligraphy is getting better and better, and he has become his own. Originally, I wanted to learn to be an excellent official and benefit the people, but I didn't expect the ink sea to go boating and winding, and my calligraphy accomplishments gradually became a generation of masters.
