永楽帝
In 1424, Zheng He traveled to Palembang in Sumatra to confer an official seal and letter of appointment upon Shi Jisun, who was placed in the office of Pacification Commissioner. The "Taizong Shilu" 27 February 1424 entry reports that Shi Jisun had sent Qiu Yancheng as envoy to petition the approval of the succession from his father Shi Jinqing, who was the Pacification Commissioner of Palembang, and was given permission from the Yongle Emperor. On 7 September 1424, Zhu Gaozhi had inherited the throne as the Hongxi Emperor after the death of the Yongle Emperor on 12 August 1424. When Zheng He returned from Palembang, he found that the Yongle Emperor had died during his absence.
