When she was working as a maid in the Yongyi Hou Mansion, she was made things difficult by the steward for visiting her mother, and unexpectedly she was favored by the old feudal lord of the Hou Mansion. In order to allow his legitimate grandson Wang Yan to continue his heirs, the old feudal lord insisted on marrying her to the prince. From a maid to the crown prince's concubine, she suffered all the neglect and difficulties, but she was always down-to-earth, gentle and forbearing, and gradually impressed the crown prince. After getting married, Agui became pregnant, and finally she and her son truly stayed together and successfully gave birth to their son, and the family of three lived a stable life.
