九月初一，征召天下能够驯养鹰的人，全部到东京集中，一万多人来到。初八，彗星从五车出现，扫过文昌，到房宿而灭。
冬十月丙午，诏曰： 先师尼父，圣德在躬，诞发天纵之姿，宪章文武之道；命世膺期，蕴兹素王。
On September 1, all the people in the world who were able to train falcons were summoned to gather in Tokyo, and more than 10,000 people came. On the 8th, a comet emerged from Wuche, swept across Wenchang, and disappeared into Fangsu.
