小年 Little New Year/Minor New Year

4. Paste paper-cuts to windows 
贴窗花

In the Little New Year, old couplets and paper-cuts from the previous Spring Festival are taken down, and new window decorations, New Year's posters, and auspicious decorations are pasted up. 
过小年时，要把去年春节贴的春联和窗花取下，贴上新的窗花，年画，和各种大吉大利的装饰品。
