Modern young people always like to put some personalized ornaments when decorating wallpaper at home, because everyone thinks it looks personalized and fashionable. But from the perspective of feng shui, I suggest that you don't choose that kind of round decorations, because square decorations often represent calmness; The round one shows signs of instability in geomantic omen.
Therefore, from the perspective of geomantic omen, square objects should be placed in the bedroom, and round objects should not be placed in the bedroom.
Generally speaking, when we decorate our homes, we usually like to put some small objects in the bedroom. Modern young people, in particular, tend to be fashionable, like to show their individuality and want to put some special ornaments in their bedrooms. Then it is suggested that some square objects can be placed at home, which will be more conducive to Feng Shui.
