There were many calligraphers in the Ming Dynasty, and the one who achieved the greatest achievement was Dong Qichang in the late period.
Dong Qichang’s calligraphy is easily found online due to its outstanding achievements.
Let me introduce to you the situation of Chinese calligraphy and painting in the Ming Dynasty:
Early Ming Dynasty: Calligraphy only followed the tradition of the Yuan Dynasty and had not yet formed its own characteristics. The famous calligraphers at that time included Song Ke, Song Can and Song Guang, as well as Zhan Xiyuan, Du Huan and others. The calligraphy of the Three Song Dynasty and Zhan Xiyuan and others paved the way for Taige style.
Mid-Ming Dynasty: Literary calligraphy revived, and calligraphers turned their interest to ancient calligraphy. For example, Li Dongyang studied Yan Zhenqing and Li Yangbing, Wu Kuan studied Su Shi, Shen Zhou studied Huang Tingjian, Zhang Bi and Zhang Jun studied Zhang Xu and Huai Su, etc. On the basis of inheriting the excellent tradition, their calligraphy pays more attention to the beauty of form and the expression of personal feelings. Finally, Wu School calligraphy appeared in Suzhou, whose representatives are Zhu Yunming, Wen Zhengming, Wang Chong, etc.
Late Ming Dynasty: Many calligraphers with unique styles and outstanding achievements appeared. Such as Xu Wei, Xing Dong, Zhang Ruitu, Dong Qichang, Mi Wanzhong, Huang Daozhou, Ni Yuanlu, Wang Duo, Fu Shan, etc. Xu Wei expressed his anger in his cursive writing. Then came four people including Xing Dong, Zhang Ruitu, Dong Qichang, and Mi Wanzhong. Xing Dongguang studied calligraphy from famous calligraphy masters in Jin, Tang and Song Dynasties, and left many works that copied ancient calligraphy. His calligraphy is vigorous, calm and round. Zhang Rui's calligraphy style is unique and unique, taking a different approach from the calligraphy of the Jin and Tang Dynasties. He uses various styles of writing, giving people a strange and unique feeling. Mi Wanzhong is from the same clan as Mi Fu in the Song Dynasty. He specializes in rice calligraphy and his calligraphy is calm and vigorous. He has been famous for his calligraphy in the north for 40 years. In addition, there are Zhao Huanguang, who created grass seal script, and Song Jue, who specialized in official script. But in the calligraphy circle of the late Ming Dynasty, Dong Qichang had the greatest influence. The person who created a generation of calligraphy style should be Dong Qichang.
Dong Qichang also worked in regular script, running script and cursive script, forming a calligraphy style that is raw, clumsy and elegant. In the theory of calligraphy, he emphasized that calligraphy has ancient meanings, and believed that calligraphy must be practiced before it can be proficient, that is, using a clumsy attitude to cover up the proficiency of the technique, so as to express the "morale" of calligraphy. He attached great importance to the cultural and artistic cultivation of calligraphers, advocated reading more and more authentic works of ancients, and emphasized reading thousands of books and traveling thousands of miles to improve artistic understanding. These are consistent with the northern and southern sects he proposed in painting theory. Dong Qichang created an elegant style that seems to be otherworldly. In addition, Huang Daozhou's stubbornness in the late Ming Dynasty, Ni Yuanlu's idiosyncratic new attitude, and Wang Duo and Fu Shan's calmness and profundity all reflected the great changes in the calligraphy world in the 10 to 20 years before the fall of the Ming Dynasty. These changes continued until Early Qing Dynasty.
