The wisdom of the Jews is recognized. If they can do business, if they do scientific research, they are the best scientists, 22% of the world's Nobel Prizes have fallen into the hands of Jews, but their total population is now less than 0.25% of the world's total.
Are the Jews really smarter than other peoples? Not necessarily, the main reason is that they attach great importance to knowledge and education internally, and they love freedom by nature, so they can be flexible. There are many well-known figures among the Jews, such as Freud, such as Einstein, and even many people who do not know that Marx was actually Jewish.

As famous as the intelligence of the Jews was the European aversion to Jews, which was particularly evident in Germany during World War II.
Hitler's targeting of the Jews was so excessive that there were commissioners in german embassies dealing with the Jewish question, and all the Nazis tried their best to incite others to join in the anti-Semitism, and of all the captives, the Jews were also persecuted the most, as evidenced by the concentration camps. According to incomplete statistics, a World War II caused more than 6 million Jews to die under the Nazi butcher's knife, including even 1 million children.
So why did Hitler target the Jews so much? In fact, if Hitler himself really hated the Jews, it is not certain, the reason why he targeted the Jews so much was actually to meet the needs of the Nazi Party, and the real anti-Semitism was the entire Nazi faction, and Hitler naturally had to put the Jews as targets in order to sit in the position of leader.
So the question is, obviously they are all caucasians, how do the Jews distinguish between Jews?
First of all, the Jewish people, as a branch of the Semites, are still different from the Germanic peoples, just like others look at Asians, but we can easily see the difference between the people of different countries and nationalities. The Jewish nose is very distinctive, generally bulging in the middle of the nose, forming the shape of an eagle hook nose. And although Jews are Caucasian, they are generally black-haired and black-eyed, which can be recognized at a glance.
And the habits of the Jews are clearly different from those of other peoples in Europe. China is a country that does not have a religious nature, so it is difficult to understand this point, and it can be said that foreign religious culture is integrated into their marrow.
Europeans generally believe in Christianity, and the vast majority of Jews are followers of Judaism, although Christianity is divided from Judaism, but after such a long period of evolution, many religious practices are completely different. The Nazis could accurately identify the Jews by looking for those who were not proficient in memorizing Christian doctrines and whose Christian rituals were not standardized.
One of the most important ways of distinguishing comes from a unique Jewish custom, which is called the "covenant" in Hebrew and is usually held on the 8th day after the Jewish birth. The "covenant" part of the child's body will leave traces, and as long as this part is examined, it is easy to distinguish the Jews, and it is almost accurate to grasp one by one.
Perhaps the Jews themselves could not have imagined that it would be their unique customs that revealed the filling.
