The Western Xia people systematically organized knowledge during the process of creating characters and compiling books,which is an important manifestation of Chinese culture taking root and flourishing in border areas.The Western Xia phonetic and semantic enlightenment books laid the foundation for the formation of the knowledge system.By finding the common points of characters with unified concepts such as phonology,form,and meaning,and then classifying or extending them into interpretations or sentences,a network of various characters and knowledge points is formed through the comparison of similarities and differences,further enabling the knowledge system to expand effectively in a certain direction.The Western Xia text Sheng Li Yi Hai is a localized encyclopedia written by the Western Xia people, integrating various types of knowledge.Its knowledge classification is more mature than that of the phonetic and semantic enlightenment books.The connection between knowledge,the introduction of foreign knowledge,and the shaping of local knowledge are all beneficial for guiding the people to face the ocean of knowledge purposefully,efficiently,and appropriately.In addition, taking the stories of Daji and He Yan as examples can fully reflect the mutual supplementation between the encyclopedia and folk knowledge.The encyclopedia provides an important reference for production and life,and at the same time,folk knowledge is carried forward in the form of poems and proverbs along with the editing of books.During the process of exchanges and integration among multiple ethnic groups,the Western Xia encyclopedia combines practicality,entertainment, and speculation, enabling knowledge to be effectively disseminated and preserving human wisdom in a systematized form.
