My Favorite Chinese Festival
Spring Festival is my favorite.It is the most important festival in China.It usually comes in January or February.
I like it very much because I have lots of free time during the festival.I can decorate the house with beautiful lights and flowers.It's quite a bit full.There is always a big family dinner on New Year's Eve.Dumplings are the most traditional food.The next morning we put on our new clothes and visit our relatives.And I can get some lucky money in red packets from my parents ，which carries their wishes to me.
Spring Festival makes me excited.
