It is not obligatory, but you can give whatever you want. You can bring something special that describes your country. Spring has come, but weather is very cold in Russia. That is why bring warm clothes. I suggest you to go very famous places in Russia. I have list of places such as Kizhi Island, St. Sophia Cathedral, Lake Baikal, Suzdal, Moscow Kremlin, Hermitage Museum, Bolshoi theatre, Moscow Metro, Kuskovo Estate, Central House of Artist and Saint Basils Cathedral. These top tourist attractions in Russia and l hope the trip will leave unforgettable memories for a lifetime.

Nature gives us everything necessary for its existence. But, often we don't appreciate these gifts, without hesitation, plucked flowers and branches, without giving anything in return. We think that this is trivial, it will grow new ones. Turning around, it's hard not to notice how all the same beautiful nature. We just need to learn to appreciate her!

Природа дает человеку все необходимое для его существования. Но, часто мы не ценим эти дары, не задумываясь, срываем цветы и ветки на деревьях, не давая ничего взамен. Нам кажется, что это мелочь, ведь вырастут новые. Обернувшись по сторонам, сложно не заметить - как же все таки прекрасна природа. Нам нужно лишь научиться ценить её!
