甲申永樂二年四月。冊立世子御名高熾為皇太子。郡王高煦為漢王。高燧為趙王　擢在善世道衍為太子少師。始復姓姚賜名廣孝。上自是稱為姚少師。而不名亦終不蓄髮娶妻。居止多在僧寺。甞賜二宮人亦不近。上乃召還之。

In the jiashen year, the second year of the Yongle reign (1404), in the fourth month, the imperial eldest son, whose taboo name was Gaochi, was invested as Crown Prince; Commandery Prince Gaoxu was invested as Prince of Han, and Gaosui as Prince of Zhao. The Left Exalter of the World Daoyan was promoted to Junior Preceptor to the Crown Prince; he was first restored to the surname Yao and granted the personal name Guangxiao. From then on, His Majesty addressed him as "Junior Preceptor Yao" without using his personal name. He still never grew his hair nor took a wife, and lived mostly in Buddhist monasteries. Once, two palace ladies were bestowed upon him, but he would not approach them, so His Majesty recalled them.
