Tsao chen-yung(1755-1835)assumed a position of Grand Councilor for about fourteen years during the early years of Tao-Kuang. He was satirized as "mediocre" by his contemporaries, and blamed as "neither literary nor righteous" after his death, which was contrast to his posthumous name Wen-Cheng. However, according to my research based on such historical sources such as the Ch'ing Shih Lu and the Archives of the Palace Museum, this paper offers an attempt at proving his achievement in many respects during his official career as well as a reevaluation on him. .
