According to relevant statistics, there were nearly 6 million Jews who were "ethnically cleansed" by the Germans in World War II, so could the Jews at that time escape the fate of being hunted down and killed by hiding their identities?
First, the plan to kill Jews was premeditated and did not happen overnight, and the vast majority of Jews had no time to react.
On November 9, 1938, at the instigation and behind-the-scenes manipulation of the German Nazi Party, a large number of thugs systematically attacked a large number of Jews living in Germany and Austria. Throughout the day, the mob destroyed and burned more than 200 synagogues and more than 7,000 Jewish shops, killing nearly a hundred Jews and arresting more than 30,000 Jews. Because many of the broken glass slag of the windows fell to the ground that night, this is the famous "Kristallnacht" incident. Under such a "moving" name, it marked the beginning of the nazi organized bloody massacre of Jews. In fact, long before Kristallnacht, the atrocities of Nazi Germany began after Germany's illegal annexation of Austria in March 1938, when tens of thousands of Jews were arrested and executed in concentration camps as a large Jewish population.
Second, the Appearance of Jews is distinctive and difficult to hide from the crowd.
Jews generally had black or brown hair, unlike most Europeans who had black eyeballs. The most obvious feature is their nose, which is large and curved inward, which is often called "eagle nose", which is very different from the almost straight nose of the Germans. It is said that an important means for the Nazis to distinguish whether they were Jews at that time was to use a ruler to measure the people who needed to be examined, and if the nose exceeded a certain size, they would be considered Jews to arrest them. Moreover, most men in Jews are accustomed to beards, because they never shave off, so they are almost always bearded. In addition, most of the Jews can also be distinguished from their clothing, and they usually like to wear black clothes and black hats.
Third, the most obvious feature: the use of Judaism as practiced by the Jews.
In addition to praying daily, devout Jews must go to the synagogue regularly to pray. The Nazi mob would take advantage of the Jewish habit of squatting outside the church, and even more so would use the information on Jewish believers left in the church to carry out systematic searches, through which few Jews could escape.
Fourth, through threats or inducements, Jews were made to report each other.
Whenever the Jews were captured, the Nazis would continue to capture more Jews through the betrayal of these captured Jews, and of course only a very small number of Jews would not stand the test and betray their compatriots. However, because the persecuted Jews in history have long formed a characteristic of settlement, even if individual Jews betray their compatriots, the blow is often very huge.
Finally, Germany at that time implemented a policy of Jews and improved national information.
As mentioned above, there was a strong atmosphere of "anti-Semitism" in German society long before the Nazis systematically slaughtered the Jews. In order to facilitate the distinction between Jews, Jews who went to public places at that time had to wear symbols representing their Jewish identity, and many Jews had long been known in society. More importantly, Germany has formed a relatively complete national information database in the 1940s, whether it is the basic information of each person or their bank records, consumption records, and medical records are very detailed. After Hitler came to power, this information greatly facilitated hitler's organization of the massacre of Jews.
Since the Middle Ages, Jews have often experienced unfair treatment by other races and have been forced to wander the globe for more than a thousand years. By the time of World War II, the persecution of Jews had reached its peak. Precisely because Jews were good at earning wealth, those in power in Europe often attacked Jews in order to raise funds. So the Jews, who had long been accustomed to being suppressed, did not expect to experience such a great pain in World War II.
