新五代史
Li Cunxu was killed in a mutiny at the capital Luoyang in 926, and Li Siyuan subsequently claimed imperial title. Either that year (as stated by the "New History of the Five Dynasties") or later, in 928 (as stated in the annals of Li Siyuan's reign in the "History of the Five Dynasties", which otherwise lacked biographical information for her in its biographies for Later Tang empresses), she was given the imperial consort title "Shufei" (淑妃). (According to the "History of the Five Dynasties", Lady Wang, who then carried the title of the Lady of Han, was given the lesser consort title of "Defei" (德妃) at the same time.)
