Abstract: This paper analyses the Tai Chan g temple (known as the administrative department of Central Government in the Han Dynasty) in a organizational way, pointing out that the departments in the Nine -Temple administrative system in the Han Dynasty were cross-functioned. In the whole organization existed the problems of indefinite purposes, redundance and separation of each department. The Tai Chang Temple had set up official positions very early and stood above all other temple s because of its bulky organization. But the Temple was later reduced to Qingshui yamen (Governmental Department which is of minor importance and usually slack) owing to its separate administrative functions and its not assum ing important government responsibility.
