May 9 is a special and sacred date in the history of Russia. In 2020, marks 75 years since the Great Victory over the Nazi invaders. All these years, the memory of the heroism of the people lives in the heart of every Russian. And this memory should not disappear! Tens of thousands of our countrymen fought with unparalleled courage and heroism. During the war, over 11 thousand soldiers became Heroes of the Soviet Union. This title was the highest sign of courage. The main slogan of those days was: “Everything for the front, everything for victory! "Therefore, the smallest citizens of our country should know about this. I believe that each of us must daily think about the world and fight for it. The memory of the heroes will forever live in our hearts. We will always remember their feat. We will be grateful, because they gave us a happy and peaceful life. Our family respects this holiday very much.

This year the victory parade will not be due to quarantine. But I think that we should not forget about this great holiday.
