褅袷（上蹄帝反鄭注禮記云褅大祭也下咸甲反白虎通曰三年一袷五年一褅說文並從衣帝合皆聲）。

"Imperial grand sacrifices" (褅袷): The first character [褅 has the fanqie] ti + di (ti). Zheng [Xuan]'s commentary on the Book of Rites says: 'The di (褅) is a grand imperial sacrifice.' The second character [袷 has the fanqie] xian + jia (xia). The Baihu tong says: 'Once every three years is the xia-sacrifice; once every five years is the di-sacrifice.' The Shuowen jiezi says: 'Both have the clothing radical (衣), with di (帝) and he (合) acting as phonetics.'
