My Christmas Holidays:
On my Christmas Holidays I didn’t have any day I didn’t make anything.
On 25th December I went to my grandpa and my grandma’s house to have the Christmas lunch. In the afternoon I went to see “Pastorets”, and in the evening I stayed in my home with my family and we watched the TV.
On 26th December I went to my other grandma’s house for having another Christmas lunch. And in the afetrnoon I went to see “Pastorets again.
In 31st December I went to campelles with my cousin and my aunt, and two other families and we slept two nights in a hotel. In the night we ate the grapes at 00:00, we laughed a lot and we had fun.
In the morning of 5th Jenuary I went to visit the “pageboys” of the kings and in the evening I went with my little cousin to give the letter to the kings of “Orient”.
And on 6th I opened the presents in my house and at my grandmpa’s house and we had lunch, and for dessert we ate the ring-shaped cake of the kings.
I had a very nice Christmas holidays… But there were very short!!!

Christmas is a holiday on December 25th celebrating the birth of Jesus Christ. Christmas has now become more and more popular in VietNam, especially to young people. On this day, people often decorate their houses and prepare presents,... . Even so, many households in big cities buy the Christmas tree and hang lights and small bells upon it. Children also love Christmas day so much. They prepare clean stocks for receiving the presents from the Santa Claus. How about the celebration? On Christmas Eve, people often sing Christmas Carol, meet friends, relatives to make a wish for them. Some people often impersonate Santa Claus and give present to everyone. All Christians go to church on this day. In England and Australia, people often make Christmas cake - a traditional food made for Christmas day.

I really want to tell you about my friend, one of my best friend is Tuan. We were  classmate during our five years at  Da Nang University of Technology. He was a good student of my class. He has black hair and bright eyes and is very good – looking. Tuan and I had many things in common, especially, our hobbies. We both traveling, billiard, table tennis, reading book and singing.

He has a kind heart and is easy to get on with everybody. The deeper our mutual understanding becomes the more we feel closely attached to each other. We are the best pupils in our class. Tuan is always at the top. He is good at every subject, but he never shows pride in his abilities and always tries to learn harder.

Tuan’s family is not rich. His parents are farmers. He often spends most of his free time doing useful things to help his parents. I Tuan very much because of his honesty and straight forwardness. He is always ready to help his weak friends in their study; as a result, lots of friends, thanks to his whole-hearted help, have become good ones
