Tzu-chung

— There are, of course, a number of counties where the descendants of pre-Ch'ing natives still constitute a significant portion of the local population. Tzu-chung county, midway between Ch'eng-tu and Chungking testifies: Tsu-chung does not have any native clans that can be traced back more than six hundred years. [Among the old clans] six- or seven- tenths came from Hupei during the early Ming period.
