Applying the methodology of quantitative analysis, the writer, in this paper, comparatively analyzes one fundamental variable, namely, the highest ranks after leaving of the mu-yu [幕友, staff members] of Tseng Kuo-fan's mu-fu [曾國藩幕府] as well as its related organizations [hereafter referred to as Tseng's mu-fu ], who entered by periods from 1853 through 1872. The major findings of this study are as following. Firstly, the category of local officials, that amounted to 452 persons, and constituted almost 70 percents, were the most of the highest ranks after leaving of Tseng's mu-yu. Then, the category of the unspecified ranks amounted to 138 persons, and constituted merely more than 20 percents. The other four categories—central officials, military officials, diplomats in foregin service, and the other—constituted together only more than ten percents. Secondly, the tendency of vicissitude of every category of their highest ranks after leaving all depended upon the category of local officials. It was always the most among all categories at the same time, no matter all periods, or each stage. There were two cardinal causes of the vicissitude of every category. One was the heaviness and lightness of the mission with that Tseng was burdened, and the highness and lowliness of his post, situation and attitude. The other was the location of Tseng's core mu-fu. The former Tseng's mu-yu that were appointed governors or viceroys almost spread over then whole China with their huge inflential power. Thirdly, Tseng's mu-fu was not only the place where the talent met together, but the place where the perspective talent were cultivated and trained. In short, the gentlemen that were in power should urged themselves the necessity of transferring the folk-custom, cultivating the talent, and training the successors.
