The Yongle Emperor's successor (the short-lived Hongxi Emperor (r. 1424–25), or, more likely, the Xuande Emperor (r. 1425–35)) continued the Yongle era's policy toward the "Wild Jurchens". In 1425, the Liaodong regional commissioner, Liu Qing, was ordered to build ships for another expedition down the river, and in 1426 Yishiha sailed again.
