A Chinese Biographical Dictionary/Chu Chan-chi
432 Chu Chan-chi 朱瞻基. A.D. 1398-1435. Eldest son of Chu Kao-chih, whom he succeeded in 1425 as fifth Emperor of the Ming dynasty. His reign was marked by the rebellion of his uncle, Chu Kao-hsü, and by a revolt of the Kuangsi aborigines. Annam was left to itself, and the north-western frontier which he occasionally visited was withdrawn to a point in 宣化 Hsüan-hua in Chihli. A well-meaning monarch, he lightened the grain tribute, allowed commutation in rice for all penalties, and in 1429 established custom-houses at important centres. By organising within the palace a school for youthful eunuchs, he fostered their growing power. His favourite concubine, who palmed off on the childless monarch a supposititious son, succeeded in displacing the Empress. Canonised as 宣宗章皇帝.
