Wax printing is a traditional Chinese folk textile printing and dyeing handicraft, and one of the four major printing techniques in ancient China. Wax printing is the process of using a wax tool dipped in melted wax to paint flowers on cloth, and then immersing it in indigo dye. After removing the wax, the cloth surface presents various patterns of blue background white flowers or white background blue flowers. At the same time, during immersion, the wax used as a dye inhibitor naturally cracks, giving the cloth surface a special "ice pattern", which is particularly charming. Using wax printing to make decorative bags is both fashionable and minimalist. At the same time, due to pure handmade painting rather than copying, the pattern of each bag is different, and each bag is unique.
