Abstract: “Maogusi” Drama，originated from traditional Tujia dance，has come through an accumulative process in its historical change.On the one hand，elements are constantly added to show new content of the era in its performance;on the other hand，it contains some original traces of the old form.This seemingly contradictory performance shows the inner logic and order of “Maogusi” as a primitive drama in its development.

Key words:  Tujia People;“Maogusi&rdquo, (a kind of Tujia drama);performance;historical change
