What do people put up on Christmas?

People usually put up a tree. Either a real or fake one. You can usually but both kinds in your local area. On the tree, most everyone I have met has put ornaments on their tree for decoration, including me.

You should put stockings over your chimney, holly hanging on top of one of your doorways, and decorate your house with pretty decor.

You should put up a wreath and Christmas lights outside. Maybe decorate a tree or two.
