       Hi, Liu Lin. Thank you for your Christmas card. 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 the
biggest 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
