Imperial records did not explain why there was a difference of 24 hours between the times when the Empress Niohuru and Noble Consort Yi were elevated from their original statuses to the same position of empress dowager. According to Tony Teng, Noble Consort Yi and Sushun had a quarrel over the granting of honours after the Xianfeng Emperor's death. It is believed that the Empress, as the primary wife of the recently deceased emperor, had supported Noble Consort Yi, thus forcing Sushun to yield.
