癸亥晦，日有食之，避正殿，寝兵，不听事5日。诏曰：吾德薄致灾，谪见日月，战栗恐惧，夫何言哉！其上书者，不得言圣。

In the day of Gui Hai, the last day of the month, there was a solar eclipse(the emperor) avoided the throne room, suspended all military activities and did not handle official business for five days. And he proclaimed,‘My poor character has caused this calamity, that the sun and the moon were veiled. I am fearful and trembling. What can I say?’...Anyone who presents a memorial is not allowed to mention the word ‘holy’.
