Car introduction: In front of the concentration camp is the Auschwitz Railway, which is the biggest reason for choosing this location. When the "death train" filled with "prisoners" arrived at the Auschwitz platform, people would be kicked out of the carriages, not allowed to carry belongings, and forced into male and female rows. SS guards were armed with guns and leashed wolfhounds. The notorious doctor Joseph Mengele would divide people into two categories: those who could work or go to the gas chambers. If necessary, they would open the mouths of the elderly and observe their teeth to determine whether they could work.
