But whence came the officials? Kao Tsu and his supporters, as farmers from eastern China, looked down upon the trading population to which farmers always regard themselves as superior. The merchants were ignored as potential officials although they had often enough held official appointments under the former dynasty. The second group from which officials had been drawn under the Ch'in was that of the army officers, but their military functions had now, of course, fallen to Kao Tsu's soldiers. The emperor had little faith, however, in the loyalty of officers, even of his own, and apart from that he would have had first to create a new administrative organization for them. Accordingly he turned to another class which had come into existence, the class later called the _gentry_, which in practice had the power already in its hands. The term "gentry" has no direct parallel in Chinese texts; the later terms "shen-shih" and "chin-shen" do not quite cover this concept. The basic unit of the gentry class are families, not individuals. Such families often derive their origin from branches of the Chou nobility. But other gentry families were of different and more recent origin in respect to land ownership. Some late Chou and Ch'in officials of non-noble origin had become wealthy and had acquired land; the same was true for wealthy merchants and finally, some non-noble farmers who were successful in one or another way, bought additional land reaching the size of large holdings. All "gentry" families owned substantial estates in the provinces which they leased to tenants on a kind of contract basis. The tenants, therefore, cannot be called "serfs" although their factual position often was not different from the position of serfs. The rents of these tenants, usually about half the gross produce, are the basis of the livelihood of the gentry. One part of a gentry family normally lives in the country on a small home farm in order to be able to collect the rents. If the family can acquire more land and if this new land is too far away from the home farm to make collection of rents easy, a new home farm is set up under the control of another branch of the family. But the original home remains to be regarded as the real family centre.
