用英语介绍一下圣诞节习俗。不少于6句话

开心的送祝福给周围人
When you hear Christmas songs, instead of acting grumpy, smile and whistle along. Being cheerful during the Christmas season really will help in spreading Christmas spirit to those around you, plus it helps you enjoy it more too.
Wish others a Merry Christmas if you know they celebrate Christmas. If you’re not sure, just say "Happy Holidays"! Either way, you are spreading the holiday cheer.

Decorate your house for Christmas. The possibilities for decorating are nearly endless. Put Christmas lights on your house. Hang mistletoe in the doorways (particularly if you know that special someone is coming over,) hang a homemade wreathon your door, or put Christmas figurines like Santa or Rudolph out on your counters.
