The bamboo paper making technique is a handmade papermaking technique that has been passed down among the people of Huangyan for more than a thousand years and is still used in Ningxi and Fushan areas. During the Tang and Song Dynasties, Huangyan had used green bamboo, mulberry bark, mountain hemp and rattan-like plants to make rattan paper, jade paper, flower paper, small white paper and music paper. Huangyan's handmade papermaking was famous in the Tang Dynasty. Mi Fu, one of the four great calligraphers of the Northern Song Dynasty, recorded the handwritten edict of Li Ang, Emperor Wenzong of the Tang Dynasty, praising Huangyan rattan paper: "Take Taizhou Huangyan rattan paper and beat it until it is ripe. Peel it off halfway and use it. It is smooth, clean, soft and ripe. It will not grow hair when rolled up." It praised its excellent texture. Since the Republic of China, Huangyan's bamboo paper production has gradually turned to the production of thousand-piece paper. The production of thousand-piece paper completely follows the bamboo paper making technique passed down from generation to generation. It uses bitter bamboo (green bamboo) that is abundant in the western mountainous area of Huangyan as the main raw material for papermaking. First, cut the bitter bamboo into about 3 feet long, pound it into pulp with a water pestle, and then put it into the cellar with oyster ash water for fermentation; take it out after more than a month, wash off the ash; then pound it into powder and drop it into the trough, copy it into sheets by hand, dry it in the sun, cut it into pieces with a knife, and then cut it crosswise on both sides. It is named because a thousand sheets are collected every day, or a thousand sheets become "one piece" (meaning volume). The production of thousand sheets uses a water pestle, and mountain stream water is used to impact the water pestle, which automatically pounded. The production of thousand sheets is family workshops, and it was spread to every household during the Republic of China. Before the founding of the People's Republic of China, it was the main source of economic income for farmers in Banlingtang Village, Fushan Township, Huangyan. Because bitter bamboo is abundant in the area, and bitter bamboo has been a good material for papermaking since ancient times, local farmers adapt to local conditions, erect pestles along both sides of the pit to pound materials, build factories to make paper, and every household makes thousand sheets. Bamboo paper production process: The bamboo paper production process involves 15 steps, including bamboo chopping, cutting materials, pounding materials, soaking materials, pickling materials, drying paper, and sun drying paper, and each step is carefully crafted. "Qian Zhang" paper has a rough texture and strong water absorption. It is also called straw paper. It used to be an indispensable daily necessity for local people. Nowadays, this kind of paper is mainly used for funerals, sacrifices, copying family trees, making firecrackers, etc. It can also be used for mechanical cleaning, archival document seals, etc. It is still widely used in daily life among the people. At present, the bamboo paper making technique has been selected into the intangible cultural heritage list of Zhejiang Province and Taizhou City, and the Banlingtang Cultural Hall has also been rated as the intangible cultural heritage inheritance base of Huangyan District.
