A different culture keeps my eyes and mind open. When I stayed in Russia as an exchange student, I learned about it.
One day, a Russian friend invited me to a well-known restaurant in Moscow（莫斯科）. I looked forward to trying local food. After arriving there, I found nothing on the table but several small plates, on which there were nuts, a few slices（片）of tomatoes, and several pieces of onions. Although the dishes were simple, we drank a lot and I felt the passion（热情）from the bottom of his heart. In China, when we invite friends or relatives, we always treat them to a big dinner. We buy as much food as we can to show our friendliness.
What a different culture it is! Even though we try our best, it's very difficult to get used to their customs.
Another Russian custom also impresses me deeply. As we know, it is very cold in winter there. When winter comes, Russians love to swim. They even take their kids outside together. Like their parents, Russian kids rub（擦）their bodies with snow before jumping into the water. Although the water is freezing cold, they all play happily in it.
What fun it is to know about a different culture!
