Corresponds
Have you ever corresponded? When it is the present time, We easily use the mail than correspondence. Here, it is not especially scrupulous whether a letter performs or mail performs.
When considering an international problem and international cooperation, unless the thing of its own country also considers a foreign thing, of course, it is not arranged. I think that the method best for understanding a foreign thing is making a foreign friend, and exchanging the culture of each other country, and an opinion.
Although it may be difficult to actually make a friend in a foreign country, I think that what is necessary is just to be able to make a friend taking advantage of something.
Incidentally I got tie people's friend with the little happening. Moreover, correspondence is also considered as the Chinese child. I am pleasant to hear the customs which Japan does not have. Please carry out correspondence and mail, if there is surely a cause!
