《宋史·本纪·卷三十五》
二十日，在太庙附祭高宗神主，下诏说： 肤最近下诏要服丧三年，大臣多次请求免服上殿听政，所以肤穿素衣在内殿听政。
丙戌，祔高宗神主于太庙，诏曰： 朕比下令欲衰绖三年，群臣屡请御殿易服，故以布素视事内殿。
On the 20th day, after offering to the spirit table of Gaozong in the temple, it was decreed that: I recently decreed that I would mourn for three years, and the ministers have repeatedly requested that I be exempted from attending court, so I wear plain clothes and hear the reports in the inner palace.
