Gen. Yu In-gwe, who had been left in charge of the Chinese troops before P‘yŭng-yang when the Emperor ordered the retreat, now sent word to the Chinese capital that as his soldiers had been in the peninsula two years without seeing home he feared they might mutiny. He received orders to return to China with his men but he decided to wait till the grain that his men had sown should ripen. The Emperor then appointed Pu-yŭ Yung the brother of the last king of Păk-je to the position of governor of all the territory formerly embraced in Păk-je. He received the title of Tă-do-dok of Ung-jin, and was urged by the Emperor to govern well. This was in 664. Sil-la took advantage of the timely cessation of hostilities to send to the Chinese camp in Păk-je and have some of her men take lessons in music from the musicians there. They also took copies of the dishes, clothes and customs of the Chinese. All these were imitated by the king and his court. Buddhism received a sudden check in Sil-la at this time for the king took the surest way to crush it out, namely, by forbidding any one to give the monks either money or rice. In 665 Gen. Yu In-wŭn received orders from China to return to that country but before doing so he performed a significant act. He made the king of Sil-la and the new Tă-do-dok of Ung-jin take an oath in the blood of a white horse that they would fight no more. This was done at the fortress of Ch‘wi-ri San and the slaughtered animal was buried there under the oath altar. A written copy of the oath was placed in the ancestral temple of the kings of Sil-la. After Gen. Yu’s return to China he was followed by Gen. Yu In-gwe who took with him envoys from Sil-la, Păk-je, T‘am-na and Japan. To render the compact of peace more binding still the Emperor sacrificed to heaven in the presence of these envoys. It is said, however, that the new ruler in Păk-je stood in such fear of Sil-la that he fled back to China soon after this. [Illustration: _SILLA BOUNDARY STONE._]
