To protect ourselves and everyone we should do the following:
+ Wear a mask when going out to public areas, crowded.
+ Antiseptic and daily body temperature measurement.
+ When you yourself have symptoms of cough, shortness of breath, you should contact the hotline of the health department.
+ Download the Bluezoon app to make a daily medical declaration.

+ Do not bring foreigners in illegally via the border.
+ .....
The above are the basic things that each of us needs to do to help the country soon end its epidemic.
This is my personal opinion, I think our state needs to deal strongly with people who illegally cross the border, spreading false information that confuses people. Because when we make strict laws, people will not consciously do something without thinking.
Each of us needs to work together to fight the Covid 19 epidemic.

Vì $a$ là số nguyên tố lớn hơn $3$ nên $a$ có thể có dạng $6k+1, 6k+5$ với $k\in\mathbb{N}$
Nếu $a=6k+5\Rightarrow 10a+1=10(6k+5)+1=60k+51=3(20k+17)\vdots 3$ và $10a+1>3$ nên $10a+1$ không thể là số nguyên tố (trái giá thiết)
Do đó $a=6k+1$
Khi đó: $5a+1=5(6k+1)+1=6(5k+1)\vdots 6$ (đpcm)

It is said that a good classroom creates friendly environment for student to learn and discover the world. It must be designed with wood desk and chair, large board, fan or air condition system, fresh atmosphere, as well as modern projector and other needed equipment. At the top of the board is always a photo of Ho Chi Minh. It’s a fundamental rule of every class so that students look up to their good example and learn from him. High tech devices are necessary for classroom because it is easier for teacher to apply new teaching method; moreover, student is more interested in studying through tablets. I want to describe in detail my classroom in primary school. Beside all the things I listed out, it is decorated with ornamental trees to create natural greenery. In the end of the room there are a lot of vivid picture, which pick up a child’s curiosity and imagination. The photos are about several topics in life like: wild animal, nature, universe, number and math,… Besides, there is often a clock hang on the wall. It consists of 1 door and 4 windows; therefore, we can save electricity from light and fan when opening all the windows. A classroom must be equipped with wastebasket, towel, bloom and mop in order for student to clean, tidy up their learning environment. Facility of a classroom has great effect on the way student’s think and behave. Hence, it is highly recommend that government construct more school and pay more attention on education.

To me, I read books in English in order to improve both my vocabulary and grammar. Besides, I combine studying and entertaining. In my free time, I often listen to English songs, watch English movies and try to translate the lyrics as well as the subtitle. Furthermore, I join an English club, where I can connect with some international friends, and they are the best teachers to teach me about English.

Everyone has their own study habits which are suitable to their routines. Personally, I have to go to school in the morning on weekdays, therefore, I spend the afternoon doing the homework. At night, after eating dinner, I often relax for a while by surfing Facebook or Youtube, and then come back to my desk. If the homework is completed, I normally practice some extra English exercises. My mother has bought several English learning books for me. On Monday and Tuesday, I have an extra course in Mathematics, so I’m a little bit busy those days. In addition, being interested in editing videos, I usually spend my free time watching videos on Youtube about this topic and practicing it myself.
