Auschwitz concentration camp is a place to travel to Poland and have to go. I went in and saw our exhibition. I felt that I couldn't finish writing a large article. I felt really depressed. Here I think it should be a place where everyone should come once and should understand the history. A few hours of visit time, in addition to being shocked by the dark past, but also admired the current German attitude to history, there are many German tourists who visit together, in the guide introduced the Nazi crimes to make the face look kind of solemn, That's the right attitude to history. Our neighbor Japan should really learn from them.
