The Dai handmade papermaking process of Mangjing Village in Mangxin Township, Menglian Dai, Lahu and Wa Autonomous County, Simao City, has completely preserved the five-step process of ancient Chinese papermaking, including the main processes of collecting mulberry bark, removing impurities, soaking, steaming, rinsing, beating, pouring paper, drying paper, and peeling paper. The papermaking tools are all homemade, including papermaking machines, sinks, mallets, scales, stones or blocks with flat surfaces, cooking pots and calendering tools. The craft is passed down from father to daughter, not from father to son, and is passed down from generation to generation. The main raw material for papermaking is mulberry bark, which is called "buried sand" in Dai language and is generally collected from April to August every year. The paper produced in Mangjing Village is mainly used to write Buddhist scriptures. It once played an important role in the cultural dissemination of ethnic minority areas in my country's border areas. From the perspective of its technological connotation, it has high scientific value and economic and practical value. Boyuzhong, a papermaking artist in the village, has been engaged in papermaking for nearly 10 years. He uses the slack season to produce earth paper, producing more than 2,000 sheets per year and earning more than 2,000 yuan a year. Bo Aidan and Bo Aizhang from Manglao Dai Village in Nayun Town are also engaged in papermaking. Bo Aizhang adds an appropriate amount of banyan bark to the bark of the mulberry tree, soaks and steams them together in a ratio of 2:1. The paper produced in this way has a smooth surface and is smoother to write on. This is an innovation in the traditional papermaking process of the Dai people. Since no chemical agents are added during the papermaking process, the paper fibers have good toughness and clear fiber veins. Now it is not only used for copying and making Buddhist supplies, but also many painters use it as the first choice for painting. Banks also roll Dai earth paper into strips for bundling RMB. In recent years, Dai earth paper has been widely used to package Pu'er tea. It is said that Pu'er tea packaged with this paper can be preserved for a long time and maintain its original quality. With people's continuous understanding of Dai earth paper, Dai earth paper is often in short supply in the market. (No pictures yet, welcome to provide.) (No pictures yet, welcome to provide.)
