How did people make paper in Han Dynasty?

Taking the bamboo paper making method recorded in the ancient book Tiangong Kaiwu in China as an example, this paper introduces the ancient paper making methods. In ancient times, the steps of bamboo papermaking were as follows: 1. Chop bamboo, float it in the pond, chop it, put it in the pond, soak it for more than 100 days, decompose it with natural microorganisms, and wash off the green skin of bamboo. 2. Cook the bamboo obtained above and put it in a bucket and cook it with lime for eight days and eight nights. 3. Take the treated bamboo out of the mortar, put it in the mortar and beat it with the mortar until the bamboo is smashed and looks like mud. 4. Throw the cloth into the curtain. Pour the mashed bamboo material into the sink and swing the bamboo material in the water with a bamboo curtain. The bamboo material becomes a thin layer and sticks to the bamboo curtain, and the remaining water flows down the water tank from the four sides of the bamboo curtain. 5. Cover the curtain to press the paper, and then repeat the curtain to make the wet paper fall on the board, thus making a piece of paper. In this way, the steps of placing materials and covering curtains are repeated, so that thousands of wet papers are stacked, and the boards are added to squeeze out most of the water. 6. Bake the wet paper over the fire. The equipment for baking paper is to build an alley with adobe bricks and make a fire in the alley. After the temperature of adobe brick rises, wet paper is pasted one by one and baked. After drying, the paper is obtained by uncovering the cover.
