Auschwitz concentration camp, even if there was psychological construction, but seeing piles of blonde hair, suitcases, leather shoes, water cups, combs... I was very gloomy. 1.1 million Jews entered by train. Women and children, as well as the elderly and sick, were directly selected to enter the gas chamber. 1.1 million Jews, Only 7,000 people survived. Keep history in mind and face the future.
