About this time Sil-la discovered that it was useless to cultivate the friendship of the Chinese powers. The Chinese territory was divided into a number of petty kingdoms and more were on the eve of being founded. None of them had strength enough to hold her own against the others, much less to be of any avail in case of trouble in the peninsula. Perhaps it was for this reason that in 535 Sil-la rejected the Chinese calendar and named the year according to a plan of her own. In China the Liang dynasty, the Northern Wei, and the Eastern Wei were all in the field, while the Ch’en, the Northern Ch’i, the Northern Chu and the Sui dynasties were just about to make their appearance and all to pass away like summer clouds before the power of the mighty T’ang. About the year 540 Păk-je moved her capital again; this time it was to Sa-ja the site of the present prefecture of Pu-yŭ in the province of Ch’ung-ch’ŭng. She seems to have had some aspirations after better things, for in 541 she sent to the Liang court asking that books of poetry, teachers of literature, Buddhist books, artisans and picture painters be sent to help in creating a taste for literature and art in that country. The request was granted. The year 543 marks an important event in the life of Sil-la. The history of that country existed as yet only in the form of notes, but now the king ordered that a congress of the best scholars of the land set to work compiling a proper history under the leadership of the great scholar Kim-gŭ Ch’il-bu. We will notice that this was about two hundred years before the earliest date that is set for the publication of the Japanese work entitled the Kojiki. And it should be noticed likewise that this history of Sil-la was not a collection of myths and stories only, but a proper history, worked up from government records which a certain degree of knowledge of Chinese had rendered the officials capable of making and transmitting. One needs but to compare the Kojiki with the Sam-guk-sa or “History of the Three Kingdoms” founded on these records to see how immeasurably the latter excels the former as a source of accurate historical evidence. It was about this time that the wild tribes of the Mal-gal and Ye-măk began to realise that the continued progress of Păk-je and Sil-la meant extinction for themselves. So in 547 they joined Ko-gu-ryŭ in an attack upon Păk-je; but Sil-la and Ka-ya rendered aid to Păk-je and the northern allies were driven back. From this time on, during a period of several years, Ko-gu-ryŭ, Ye-măk and Mal-gal were allies, and Sil-la, Păk-je and Ka-ya were allies; a sort of dual arrangement, which preserved a nice equilibrium in the peninsula.
