It's very beautiful. We had a wonderful Christmas. On Christmas Eve, we put up a Christmas tree in the sitting room and hung stockings at the head of our beds before we went to bed. We found many presents in the stockings the next morning. On Christmas Day the whole family got together and we had a big dinner. Everyone was very happy. Christmas is thebiggest festival in the western world. Which is the most important festival in China? How do you celebrate it? What is the traditional food for the dinner? I'm interested in that festival… Best wishes! Mike 收件人(To):PJmike@hotmail.com抄送(Cc):None主题(Subject):Re: FestivalsHello, Mike. Best wishes! Liu Lin 查看答案
