Few years ago i visited with the school for two week China. It was a Student Exchange. On my 18th Birthday I was on the Chinese Wall. I was Amazing. On of the wonderful places I ever seen. And years ago i visited my best in Riga / Latvija. In a neighbor city there is a place with empty building. Empty streets and empty houses, gardens. All alround was empty. In the past the soldiers were there. It was cruel and really fascinating.
