Among many subjects student learns in school, I like math the most. This is one of the compulsory subjects from primary to high school ad even university. Math teaches learner about numbers and operation. Being good at math brings us several advantages. Doing math exercise improves one’s brain and its brainstorm. Moreover, people learning math can think more logically and make up one mind. There are many subjects we can apply mathematics to solve the problem: economics, engineering and even business. Math is said to originate from ancient Greece and develop completely as today. In VN it’s an increasing number of mathematical genius such as Ngo Bao Chau. Therefore, Vietnamese are very proud of it. In my opinion, every student should be good at math or at least learn it. Since human gain lots of achievement related to math, specifically in modern society.

There are several holidays held in a year. It is Christmas holiday that is interesting. Christmas occurs on 24 and 25^th December but it starts from the beginning of the month. During Christmas, people are more friendly and gentle with each other because they believe to have a happier life without sorrow. I enjoy decorating Christmas tree and walk around the streets looking at the buildings and the trees around the city such as in squares and parks, shops and offices. Especially, there is always a big tree at city’s center, in which people gather and pray together in Christmas night. All the city is decorated with color and lights; therefore, it is a chance for citizens go out, take many beautiful photos and transfer to each other. We take part in several interesting activities like creating snowman, playing in snow, making homemade candy or cake, cleaning house. The snow is a symbol of Christmas. To me, it is a symbol of renewal and cleanliness of the upcoming event. Besides, the children enjoy receiving presents, which are put at the tree by Santa Clause. They believe he brings obedient kid joy, good health and hope for a new year. Actually, the gifts are prepared by parents or relatives in order to encourage them study and well behave with other. The tradition of giving presents originates from the old days and it becomes one of features of Christmas holiday. Christmas reinforces the belief of one’s soul and heals all sadness and dissatisfaction. In my opinion, it is essential to continue this holiday because of its beneficial role in culture of one country.
