After studying the 1500 years of painting history from the beginning of Gu Kaizhi's discussion of painting in the Eastern Jin Dynasty to the end of the discussion of painting by many people of insight such as Kang Youwei,Chen Shizeng and Xu Beihong in the late Qing Dynasty and the early Republic of China,we find that the aesthetic character of Chinese literati painting is not unchangeable.It has experienced a change from"emphasizing Qi"to"advocating Rhyme".And at the key turning point of the aesthetic character of Chinese literati painting,Gu Kaizhi,Xie He,Zhang Yanyuan,Jing Hao,Guo Ruoxu,Su Shi,Mi Fu,Zhao Mengfu and Dong Qichang,all of them have shouldered the sacred responsibility and glorious mission given by history.Especially in the late Ming Dynasty,Dong Qichang praised the painting style language of"Dong and Ju",and made a comprehensive,profound and systematic summary of the theory of"advocating rhyme"in Chinese literati painting.Therefore,to some extent,the theory of"advocating rhyme"in Chinese literati painting began with Su Shi and matured with Dong Qichang.
