董其昌是明代书学大家，也是传统帖学的集大成者。其书法成就达到很高的艺术水平，对后世的影响也极为深远。董其昌一生力追自然天成、冲逸简淡的书法风格，为我的老师邓宝剑评为：“文敏如玉、香光如烟” ——所评颇为恰当。对董其昌行书取法做更深入的研究，将有助于我们更深刻地解读其书法风格的形成过程，或许对我们自己的学习也不无启发。 本文将对董其昌行书的取法做出相应的阐述，相应集中在对其取法苏、米、赵的论述，笔者将尽力对相关问题做出合理的解释与评判。

Dong Qichang is a famous calligrapher in the Ming Dynasty, Synthesizer of the traditional hardwood calligraphy. His style of calligraphy attained rather a high artistic level and tremendously influenced the following generations. Dong Qichang spared no efforts to achieve the aesthetic qualities of naturalness and “blandness” (dan) lifetime which was evaluated by one of my professors , Deng Baojian，he says :“ like jades Wenmin’s (Zhao Mengfu) style is and like smoke Xiangguang’s (Dong Qichang)”, and I think he said exactly the point. To study Dong Qichang’s assimilation of his running script will help us understand the process of the mature of his style, maybe to enlighten ourselves as well. This paper will discoursed at great length on Dong’s study accordingly; focus on his assimilation of Su, Mi, and Zhao relatively. I will try my best to interpret or evaluate relevant contents reasonably.
