Ancient Chinese literature was not only literature, but also philosophy, history, music, and play. Moreover, ancient Chinese literature did not only belong to Chinese people, but also belong to Korean, Mongolian, and even Japanese people. Nevertheless, many people including scholars and researchers still regard ancient Chinese literature as only Chinese literature, apart from ancient Korean, Mongolian, and Japanese literature. However, everything changes like river flows incessantly. So does Chinese literature. That is why we have to look ancient Chinese literature as East Asian studies.
From this point of view, Chinese myths such as Pangu盤古 myth and Magu麻姑 myth have been shared among East Asian people througout thousands of years. Likewise, Confucian scriptures like 『Yi Jing 易經』, 『Shi Jing 詩經』, 『Shu Jing 書經』, 『Li Ji 禮記』have been important classical books among East Asian intellectuals. Besides, Changwen唱文, a sort of voice performance as well as Jiyuewu伎樂舞, a type of traditional mask play have been enjoyed by East Asian people. Therefore, we should regard ancient Chinese literature as East Asian studies.
