Based on the same presumption on the molding methods reported previously, the development steps of squeezing techniques in hand papermaking were surveyed and estimated from the analyses of hand papermaking conserved by minorities in and around southern China. The initial step of the shift from molding process was to make paper from squeezing in a deep vat dispersed plant fiber by using a screen fixed with frame. As the second improvement, a screen separable from frame was invented for production efficiency. The second step was to squeeze a suspension of plant fibers dispersed without mucilages by using the separable screen and frame and then to dry each a piece of wet sheet on a board or wall without pressing. The third step was to add the process of pressing a pile of wet sheets for improvement of paper bulk density and strength. In this pressing process, felts were first inserted between each wet sheet for preventing from mutually sticking these sheets. Finally the squeezing method was refined to reach the 'nagashizuki' technique by which a pile of wet webs are permitted to be pressed without inserted felts for peeling each sheet off.
