Ian-Tze was an outstanding Statesman and Thinker on the Spring & Autum Dynasty. In this essay an trying to research Ian-Tze’s Thought on how to administrate a Country. The main resource I used is “She-Che” (The Record of History, by She Ma-Cheng) which is an authentic Recored on Ian-Tze, Another Book I used is “Ian-Tze Chung-Chu” (The Spring & Autum of Ian-Tze): The speech and activities of Ian-Tze. I’ve found many points about his thinking in this research: To be economy and hard work, to understand and choice the Talent, to be humble to the Talent, to be kind and thoughtful to the people, everyone should be responsible to what his position, to be brave, to be honesty…… So, I think Ian-Tze had contributed to the thinking of administrating a Country very much both by his Actities and his words.
