What is the moral of window grilles?

Window grilles are paper-cut pasted on the windows before the Spring Festival in rural areas to set off the festive atmosphere. Generally speaking, the style of window grilles is relatively free, and there are no restrictions on their outlines except the "corner flowers" stuck at the four corners and the "group flowers" folded and cut. Because it adapts to the general pane and avoids affecting lighting, its size should not be too large, and attention should be paid to hollowing out and translucent. In order to enhance the artistic effect and create a strong atmosphere, many window grilles are often pasted on a window, either matching in content or echoing in form. The theme of window grilles is very wide, and there are a lot of drama stories. Window grilles are more common in the north.
