[4] Emperor Wen was forced to agree, and he sent Yuan Fu (元孚) the Prince of Fufeng to Rouran to invite her to be his empress.
Yujiulü Anagui gave Western Wei 700 carts full of goods as dowry, along with 10,000 horses and 2,000 camels.
As her train encountered that of Yuan Fu's, Yuan Fu requested that she turn her face from facing east (the honored direction pursuant to Rouran customs) to south (the honored direction pursuant to Chinese customs).
In spring 540, she was pregnant when Rouran launched a major attack on Western Wei — causing the Western Wei officials to believe that the attack was launched because she was jealous of the former Empress Yifu, who was by then a Buddhist nun.
Emperor Wen, under pressure, ordered Empress Yifu to commit suicide.
