This literature develops in the context of the country's construction and protection of independence and autonomy, with the parallel of two main components, Chinese literature and Nom literature. The works of this period were deeply influenced by ideologies such as Buddhism, Confucianism, and Taoism, creating distinct characteristics in terms of content and art. Since Vietnam implemented the Doi Moi, our country has constantly exchanged economic, political and cultural exchanges with countries in the East Asian cultural region, thereby forming a generation of East Asian literary researchers. The work of Assoc. Prof. Dr. Doan Le Giang was born in that context.
