The blank of the same specification is made of clay, and one end is engraved with reflexive characters. The height of the character is the same as the thickness of the edge of the copper coin, and it becomes a single clay movable type after fire quenching. In order to meet the needs of typesetting, when repeated in the same version, there are usually several or even dozens of commonly used words for use. If you encounter uncommon words, you can use them with the system if you are not prepared in advance. In order to facilitate the choice of words, the clay type is put in the wooden lattice according to rhyme, and a note is attached to indicate it. When typesetting, an iron plate with a frame is used as the base, and a layer of medicine made of turpentine, wax and paper scraps is coated on it, and then the required clay movable type is picked out one by one and arranged in the frame. After a frame is filled in, it becomes a version, and then it is baked with fire. When the medicine melts slightly, flatten the words with a flat plate, and after the medicine cools and solidifies, it becomes a version. When printing, just brush the ink on the plate, cover it with paper, and add some pressure. For continuous printing, two iron plates are used, one with a writing brush and the other with typesetting, and the two plates are used alternately. After printing, burn it with a torch, shake it gently with your hand, and the movable type will fall off the iron plate, and then put it back in the original wooden box according to the rhyme, and use it next time.

Wheeled typesetting tray is used to place movable type molds. The dial is disc-shaped and divided into several grids, and the movable type fonts are arranged in the grids according to rhyme. There is a vertical shaft below, which is fixed on the base. When typesetting, two people cooperate, one reads the manuscript and the other turns the dial, so that the required fonts can be conveniently taken out and discharged into the plate. After printing, restore fonts one by one in the grid.
