Do you know Ma Haichu's calligraphy?

Ma Haichu, whose real name is Wanshan, is a national first-class calligrapher and calligraphy researcher. When I was young, I was engaged in cultural work in the army, and I studied under famous calligraphers such as Li Pinzhen and Zhou Zhengshan, as well as Chinese scholars. Currently, he is the director of the Painting and Calligraphy Professional Committee of Guangdong Federation of Industry Associations and the director of China Railway Bookstore Association. His work, Mao Zedong's poem Qinyuanchun Changsha, was collected by Diaoyutai State Guesthouse. To commemorate the 70th anniversary of the victory of the Anti-Japanese War, his works were edited and published by China Post as a commemorative album.
