Yang Zaichun Mozi was born in August 1943 in Tangshan, Hebei province. He is currently a member of China Calligraphers Association, a director of Beijing Calligraphers Association, a lecturer of calligraphy series on CCTV, a professor at Correspondence University of Painting and Calligraphy in China, and the president and editor-in-chief of Beijing Sport University Press. He has held many personal calligraphy exhibitions and lectures in Japan, South Korea, Singapore, Hong Kong, the United States, Switzerland and other countries and regions, and published more than 30 monographs. Yang Zaichun, a calligrapher, had an indissoluble bond with ink for most of his life, and his artistic life was practiced between black and white of ink and paper. Because of his burly figure and dark skin, he is entangled with smoke and ink almost every day, so many friends call him "Ink Man". Over time, "Mo Ren" became his pen name. His works are not only praised by calligraphy circles, but also loved by ordinary people. At one time, he was invited to give a calligraphy lecture at CCTV. As a result, he spread the art of calligraphy to the whole world. This is one of his calligraphy works.
