The Yongle Emperor ordered his wife, Empress Xu, to care for and educate the young girl. In 1417, Sun was selected to be a consort to Zhu Zhanji (future Xuande Emperor), who was the imperial grandson-heir. In 1424, she gave birth to a daughter, the Princess Changde. When Zhu Zhanji ascended the throne in 1425, she became Noble Consort Sun (), which was the second-highest position after the empress.
