Why do you want to cut window grilles during the Spring Festival?

Make window decorations and paper cuts

Northern folk custom

Interpretation: In the old society, windows had no glass, so in winter, they could only paste paper to keep out the wind and cold. The paper is white enough. During the Chinese New Year, in order to show auspiciousness and peace, every household has to cut out red window grilles to decorate the windows, and at the same time, they are pinning their good expectations for the coming year.
