Cixi is the empress dowager of Emperor Xianfeng. Why was she buried in his east after her death?

As we all know, Ci 'an and Cixi were two Empresses of Xianfeng Emperor in Qing Dynasty. In history, Ci 'an was called Dong Taihou, and Cixi was called Empress Dowager, and the two palaces were revered together. After their death, they were buried together in Qingling Mausoleum in zunhua city, Hebei. Since ancient times, there has been a saying in China that Higashionishi is small and Dongda is expensive. As the real queen of Emperor Xianfeng, Ci 'an was named Empress Dowager on the day of Emperor Xianfeng's death, while Cixi was named Empress Dowager on the day after Emperor Xianfeng's death. In the hierarchical concept of feudal society in China, Cixi's status and position are second only to Ci 'an, so she should be buried in the west. But why are their tombs in the opposite position?

For this phenomenon, the researchers put forward three views. The first statement is: Cixi secretly designed to seize the mausoleum. According to legend, Empress Ci 'an is kind and weak, and endures Cixi everywhere. Cixi, on the other hand, is ruthless and has a strong desire for power. She is unwilling to give in to Queen Cian. Therefore, before he died, Ci 'an set a trap of "playing chess on the tomb", took the original tomb of Empress Dowager Dong as his own, and finally designed and killed Empress Dowager Dong.

The second statement is: Cixi has a strong desire for power and a tough personality. She didn't want Ci 'an to decide her burial position, so she designed to kill Ci 'an's queen. After Ci 'an's death, she monopolized the power, regardless of the ancestral system and birthright, and forced the Empress Dowager Ci 'an to be buried in the West. Although there was remonstrance in the DPRK, Cixi was too strong and eventually failed. In this way, she just took the tomb of the East.

However, the third view is that Empress Dowager Cixi cannot seize the Ci 'an Mausoleum with tricks or tricks. First of all, China attached great importance to funeral in ancient times. Even if Empress Dowager Cixi is overbearing, it is impossible to modify the burial place without authorization. Second, the names of the Eastern Empress Dowager and the Western Empress Dowager are not determined by the location of the mausoleum, but by the location where they lived before their death. Empress Ci 'an lived in Zhongcui Palace, one of the six eastern palaces in the Forbidden City, so she was called Dong Taihou. Empress Dowager Cixi lives in Palace of Gathered Elegance and Changchun Palace, so she is called the Empress Dowager, which has nothing to do with the location of the mausoleum. But which of the above three statements is true? At present, everyone is still arguing.
