At the end of the third year of Yitai, Ning Taizu died, and the later crown prince Yu Wenrui ascended the throne. The crown prince Helian was the successor, and the reign name was changed to Xiyuan. In the same year, King An concurrently served as the guardian of Anxi Prefecture and went to Xinjiang. From then on, the royal power in the imperial capital increased day by day. In the early years of Duanxi's reign, the Helian family's son Xuanyou passed away, and the Zhaoyi Zhen family was promoted to a concubine, and became the associate administrator of the Sixth Palace. The Zhen family had no children but gave birth to two daughters, the eldest daughter Yurong and the second daughter Wanxi. In this way, time is like water, always flowing without waves.
