New History of the Five Dynasties
Nothing was said about Empress Liu's identity in the official histories of the Five Dynasties and Ten Kingdoms Period — the "History of the Five Dynasties" and the "New History of the Five Dynasties". What was mentioned was that after the destruction of the preceding Tang Dynasty, Li Maozhen continued to use Tang's era name to show refusal to submit to Later Liang and continued to use the Tang-bestowed title of Prince of Qi. However, he took on much of the trappings of an emperor, including creating an Office of the Prince of Qi that had a large staff and many offices that had imperial government-like titles and creating his wife (who was not named) empress. No other reference was made in his biography in the two official histories about his wife.
