It is not known when Consort Yang became Emperor Wenzong's
concubine, but it is known that as of 837, she was an imperial consort with the rank of
Zhaorong (昭容), the sixth highest rank possible for imperial consorts. In 837, she was promoted to the rank of
Xianfei (賢妃), the fourth highest rank for imperial consorts, while fellow imperial consort Consort Wang, the mother of Emperor Wenzong's oldest son
Li Yong, was promoted from the rank of
Zhaoyi (昭儀) (fifth highest rank) to
Defei (德妃) (third highest rank). There was no indication as to whether she was involved in Yang Sifu's becoming chancellor in 838. After Li Yong's death, Consort Yang repeatedly recommended Emperor Wenzong's younger brother
Li Rong the Prince of An as the new crown prince. (As Emperor Wuzong later would allege, he believed that Li Rong flattered Consort Yang in order to receive her favor.) When Emperor Wenzong asked for the chancellors' opinions, however,
Li Jue opposed this, so Emperor Wenzong instead created
Li Chengmei, the Prince of Chen, the son of his older brother
Emperor Jingzong, as Crown Prince. == Death ==
