1, Liu E became the third queen of Zhao Heng, Song Zhenzong. In the second year of Ming Dow (1033), in March, Liu E died of illness, and posthumous title was named "Queen Su of Xianming Zhang".

2. Liu E was the first woman who was called the imperial concubine in Song Dynasty. She was often referred to as Lv Hou in the Han Dynasty and Wu Zhi in the Tang Dynasty, and later called her "a talented woman without the evil of Lu Wu".

3. Liu E is in the DPRK, which is "a sublime world". In the second year of Tiansheng (1024), Liu E wore royal robes and attended the conferring ceremony in the Song Dynasty. A courtier wrote a letter asking Liu E to "imitate the story of the marquis of Wu", and Cheng Lin also presented "Meeting the Emperor after Wu", all implying that Liu E proclaimed himself. Liu E tore up the memorial to encourage her to be emperor and threw it on the ground, saying, "I won't do such a thing that I'm sorry for my ancestors in the Song Dynasty!"

4. Liu E loved to wear royal clothes all his life, and refused to return to Song Renzong until his death, which led to criticism from the ruling and opposition parties. After the Song Dynasty, with the wide spread of literary works such as "Civet cats for princes", Liu E was framed as narrow-minded and jealous among the people, which undermined loyalty and even tried to capture the image of "a generation of traitors" in the Song Dynasty.
