There are two basic paper-cutting techniques, one is male scissors and the other is female scissors. Yang Jian cut out a shape on a piece of paper with reservation, that is, he kept the modeling lines in the picture, while the paper-cutting method of removing other parts was to cut out a three-dimensional shape and pay attention to the connection of lines. Emperor Wen of Sui's works are mainly lines, smooth and delicate, similar to China's meticulous line drawing. This method is often used in southern paper cutting.
Yin Jian cut out a shape on a piece of paper, and removed the modeling lines in the drawing during the production process, leaving a large surface instead of a virtual shape. It is concerned about whether the line is broken. This method is based on surface, enriching the picture through points and lines, and the works are heavy and solid. This method is often used in northern paper cutting. Under normal circumstances, there are both male and female scissors in a work, which are printed and lined with each other. Through the change of point, line and surface, the picture is thick and solid with female engraving, and smooth and fresh with male engraving.
