《资治通鉴·齐纪·齐纪七》
孝文帝以元丕曾经在诏令中被许以不死，就免他一死，黜为平民，让他的后妻和两个儿子陪伴他居住在太原，而杀了元隆、元超及其同胞兄弟元乙升，其他的儿子流放敦煌。
帝以丕当受诏许以不死，所免死为民，留其后妻、二子，与居于太原，杀隆、超、同产乙升，馀子徙敦煌。
Xiao Wendi pardoned Yuan Pi from death because he had been promised not to be killed in the edict. He was demoted to a commoner and his second wife and two sons accompanied him to live in Taiyuan, while Yuan Long, Yuan Chao, and his half-brother Yuan Yisheng were killed, and the remaining sons were exiled to Dunhuang.
