Empress Cao
In 930, Li Siyuan was preparing to create Consort Cao empress. She stated to Consort Wang, "I have always despised minute matters, and I do not want to be involved in ceremonies. You, sister, should substitute for me." Consort Wang responded, "The Central Palace [(i.e., the empress's palace, and therefore an alternate way to refer to the empress)] matches the Supreme One [(i.e., the emperor)]. Who would dare to step in?" Li Siyuan subsequently created Consort Cao empress, and later promoted Consort Wang to the rank of "Shufei". Consort Wang served both Li Siyuan and Empress Cao carefully, such that Empress Cao and Consort Wang became very close. However, it was said that because of this, Consort Wang effectively controlled what occurred in the palace.
