The art of printing with pounded grass is one of the "three treasures" of Renmazhai Village, Xizhang Village Town, Shan County, Sanmenxia, Henan Province, and a provincial intangible cultural heritage project of Henan Province. However, this unique and natural printing and dyeing technique was once little known. Pick the "Qianbangbang grass", a wild plant unique to the western Henan region, sandwich it between white cotton cloth, and beat it with a mallet. The juice of the grass slowly seeps into the cotton cloth. After a while, the pattern in the shape of grass leaves is printed on the cloth, full of natural charm. Two, four, and eight grass leaves are arranged in sequence, and after a while of ding-dong-dong, a piece of floral cloth is ready. Writer Yang Libo once called "beaten grass printing" the "Collection of Grass Leaves" on cotton cloth. She said: "beaten, grass, print, flower, each word can be separated, and each word separated is a process and a picture, and when they are combined, it is a story and a style. The clinking of the wooden hammer, together with the gentle plucking of the heartstrings when pounding grass printing, combine to form a beautiful music, telling the leisure and poetry of handicrafts, and expressing the grandeur and tranquility of agricultural civilization." The raw materials for pounded grass printing include white cotton cloth (commonly known as homespun cloth and coarse cloth by locals), several unique plants with rich stem and leaf slurry, dyeing function and good flexibility, such as Qianbangbang grass (scientific name sunflower, Chinese medicine name geranium). The specific operation procedure is to put the freshly picked "Qianbangbang grass" in a white cotton cloth, arrange it into a flower pattern you like, and then spread it on a flat stone, and gently beat the grass juice with a wooden stick. With each beating, the veins of the grass are clearly imprinted on the white cloth, forming a pattern of green flowers on a white background. In this way, a piece of green, environmentally friendly, pure handmade, and pure natural floral cloth is printed and dyed. If you need a floral cloth with other base colors, you need to fix the color of the pattern, use a brush dipped in pomegranate peel juice or alum water to draw the pattern, and then put it in a dye pot with the color adjusted and boiled for more than ten minutes. In this way, the base color of the dyed cloth becomes red, blue, purple and other colors, and the previously beaten grass leaf pattern becomes black. This ancient printing and dyeing technique is said to have originated in the Ming and Qing Dynasties and was lost in the early Republic of China. In recent years, Zhu Xiuyun, a woman in the village who loves folk art, has studied this technique and made handbags, scarves, round fans, T-shirts, etc., which are simple, beautiful, and not easy to fade, making this ancient folk craft rejuvenated. In 2011, the grass-beating printing technique was approved by the Henan Provincial Department of Culture as a provincial intangible cultural heritage. This unique printing and dyeing technique with regional characteristics and artistic value has once again attracted the attention of the world: "Looking at the colorful cloth, I seem to be able to listen to the natural singing of nature."
