Zhou Xiao is younger than Da Zhou 14 years old. Zhou Xiao was only five years old when he married Li Yu in Da Zhou. Because of his relatives, he often went in and out of the inner palace, which won the favor of Queen Zhong. In the second year of Germany (964), he died a week later and the palace was vacant; In September of the following year, Empress Zhong passed away, and Li Yu mourned according to the system. In the first year of Kaibao (968), Li Yu lost his mother. Because the position of queen has been vacant for four years, he negotiated to establish Zhou Xiao as the queen of the country. Li Yu ordered Chen Zhiyong, a doctor in Taichang, to organize the wedding ceremony according to the ancient and modern etiquette system, and also ordered Xu Xuan, a bachelor, and Pan You, a historian, to participate in the compilation, and Xu You, a duke of Wen 'an County, commented on the similarities and differences. Xu You was satisfied with Pan You's opinion, so Li Yu ordered him to do it according to his ceremony. 1 1 month, Li Yuli became the queen of China after Zhou Xiao.

According to historical records, the illness worsened after the big week, which was related to the secret affairs in the palace after the small week. Zhou Xiao is the second daughter of Zhou Zong. After Zhou Ehuang fell ill, Zhou Xiao often went to the palace in the name of visiting the sick. Zhou Xiao was beautiful, quiet, alert and intelligent. Her late master loved her beauty and secretly took her as his concubine. After E Huang found out, he was so angry that he lay flat on the ground and didn't look back at Zhou Xiao until he died. This theory is recorded in detail in Ma Ling's Book of Southern Tang Dynasty and Zhou Long's Book of Southern unofficial history, and Lu You's Book of Southern Tang Dynasty is also included as an anecdote.
