This beard under the Japanese army is called "sanitary beard". The origin of the sanitary Hu is Germany, and it is Hitler, the fuehrer of Nazi Germany, who carried him forward. In the 18th century, when the beard was popular in Germany, it was the beard of Professor Hagrid in the movie "Harry Potter". But this beard is not very elegant at first, and it will also cause considerable trouble when doing other things. For example, when eating, a person who does not pay attention to the residue or bread crumbs of the meal leaves on the top. It also takes time and effort to clean up for half a day. This is a very intolerable thing for a meticulous and solemn Germany. So when he came to Hitler, in order to retain the original characteristics and for a more convenient daily life, Hitler shaved off all his beards, and left the piece under his nose, commonly known as "sanitary beard". There is also an allusion to this.
Hitler was a soldier with a strong artistic beard. One day, after going to the battlefield, the German side dropped poison gas bombs. Hitler, on the other hand, took out a pre-issued gas mask. However, due to the large population of the army at that time, the mask was uniform, and no special person like him was taken into account. Therefore, his beard was extremely obstructive, so that the mask was not covered tightly, and finally Hitler suffered a lot. So when Hitler got off the front line, he shaved off his beard and left the point under his nose to retain his own characteristics.
In Japan, during this period, the Qing Dynasty was closed to the country for a hundred years, and scientific and technological thinking has long been backward. Japan, which is adept at learning, has set its sights on the West, especially Germany. The Japanese in this period were proud to eat Western food and wear suits, and due to the comprehensive copying of Western culture and political system, Japan once became a country praised by the great powers, feeling that the monarch of this country was open-minded and the people were easy to contact, but in fact, this was all a superficial scene, and the feudal remnants and militarism in Japan's bones were vigorously brewing. The Japanese elite sent to Germany was greatly influenced by Hitler's ideas, after all, there were many people in Japan at that time who admired and imitated Hitler, and both sides belonged to the fascist Axis faction. After returning home, this beard is also highly recommended.
Slowly, from politicians to soldiers, this sanitary beard soon spread in Japan because it was not only clean and easy to manage, but also retained a large degree of masculinity in men. Many soldiers in the Japanese army also believed that this beard could play a role in intimidating the enemy and boosting morale in war, because under the influence of Hitler, this beard also symbolized extreme violence and extreme democracy of the reign of terror. But when applied to the Japanese, at least in our view of China, it is a bit strange.
