What accomplishments does Wang Duo have in painting and calligraphy?

Wang Duo is a scholar as famous as Huang Daozhou and Ni, and he is the best among the three masters of painting and calligraphy. However, due to his defection, people's evaluation of his calligraphy art is somewhat derogatory. But as far as art itself is concerned, Wang Duo's calligraphy attainments are indeed the highest among the three, and his achievements are comparable to that of Dong Qichang. From Liu, Chu and Yu in the Tang Dynasty to Mi Fei in the Song Dynasty, he learned from others. According to records, because the name of his calligraphy is more important than time, he once decided to take a calligraphy class, asking for one a day, and so he took turns until his death, which was not easy for life.
