Historical accounts about Cui and his fellow coup leaders generally referred to them as the "five princes". As their titles were restored after Emperor Ruizong's ascension, they were generally considered to have been restored to their princely ranks. Because Cui's biography in the Old Book of Tang quoted an edict of Emperor Xuanzong's honoring him as the Duke of Boling, it is not completely clear whether Cui, posthumously, was formally referred to as a duke or a prince.

Cui Xuanwei's biographies in the Old Book of Tang and the New Book of Tang both indicated that this change occurred "during the time of Empress Wu," which could mean either during her reign as "emperor" or the first reigns of her sons Emperor Zhongzong and Emperor Ruizong.

The Old Book of Tang further implied that the ancestor in question was Empress Wu's grandfather, but as Empress Wu's grandfather was named Wu Hua (武華) (see New Book of Tang, vol. 74, part 1 "唐書 表 第十四". Archived from the original on 2007-10-11. Retrieved 2008-01-20.), and "Hua" did not appear to have any real resemblance to the character "Chu", it is unclear which ancestor was actually involved.
