Xinxu(新序) was published in Korea by 1492. Among the existing editions, the editions that can confirm the realities are the collections of Keimyung University, the Korean Studies Central Research Institute, Kyonggi University, Hujodang(後彫堂), and the National Assembly Library of Japan. The Keimyung University’s precious book is the 'first published book', and the old book is the 'later published book' which covers pages 69-70 and 71-72 of the first published book. It is the 'later published book' that has the same side inscribed. The second books, the Central Research Institute of Korea Studies and the Kyonggi University Collection are the first published books, and the Hujodang and the National Assembly Library of Japan are on pages 9-10, 63-64, 87-88, 107-108. The corresponding side is the 'later published book'. Comparing the editions, it can be concluded that the existing editions of the previous editions have been withdrawn two times, and in the latter editions, the existing editions of four editions can also be confirmed to have been edited three times.
In this paper, the literature based on the existing editions was studied and features of the Korean edition were presented. First, we examine the types of paragraphs. In principle, the text is composed of '11 lines and 18 characters', but on the actual version, the number of characters is shown in the table. In the Korean edition of the Joseon dynasty, a blank space appears in the original text. The erroneous letter in the Joseon book was identified the reason for the error was explained in detail.
