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.
