<My own growth>
I learned many things in trip to Russia. By contacting with various bags, animals and plants, I felt the brilliance of nature. I learned that people have accepted a favor from nature for a long period of time so the nature is very very important for us and we should protect nature. Russians understand problems of nature of their country. I think we should learn their attitude for nature. Also, I talk with Russian students aggressively so I was able to improve my skills of talking with foreign people. This trip was very significant for me!
