↑ Emperor Xiaowu's posthumous name of "Xiaowu" was bestowed by Western Wei. Eastern Wei did not recognize it, and instead referred to him as Emperor Chu. The official history of Northern Wei, the Book of Wei, written during Eastern Wei's successor state Northern Qi, thus referred to him as Emperor Chu. However, Chinese historians, following the lead of the History of Northern Dynasties, generally refer to him as Emperor Xiaowu.
