sentences:  Despite having ruled as an emperor, Wanyan Yongji was not posthumously honoured as an emperor.Instead, in 1216, his successor, Emperor Xuanzong, reverted his status back to "Prince of Wei" (衛王) – the title Wanyan Yongji held before he became emperor – and gave him the posthumous name "Shao" (紹), hence Wanyan Yongji is historically referred to as "Prince Shao of Wei" (or Wei Shao Wang).Wanyan Yongji's birth name was "Wanyan "Yun"ji" (完顏允濟); his given name was changed to ""Yong"ji" later to avoid naming taboo because Emperor Zhangzong's father was Wanyan "Yun"gong (完顏允恭).
