In 9 CE, after Wang Mang usurped the Han throne and declared himself the emperor of the Xin Dynasty, Lady Wang was created empress. Of her two surviving sons, the younger Wang Lin was considered more capable, so Wang Mang created him crown prince, while Wang An was created the Lord of Xinjia. Due to Empress Wang's blindness, Wang Mang asked Crown Prince Lin to move into the palace to attend to her.
