After the Meiji Restoration, Japan began to study western culture in an all-round way, ordered civil servants to wear kimonos and keep traditional hairstyles, and demanded that clothing culture should also be fully westernized. The main country in Japan to learn western culture is Germany, which has many similarities with Japan at that time. It is a dual constitutional monarchy and has just eliminated the feudal separatist forces. Therefore, Japan is particularly concerned about Germany's development model and has sent missions to Germany for many times to study. At that time, Japan learned everything from Germany, copied its laws, learned its political and military systems, and even learned the habit of staying in Germany. Therefore, the Japanese sanitary beard is related to Hitler's sanitary beard.
Hitler used to have a moustache when he participated in World War I, and I also saw a photo of him with a moustache. Hitler was an Austrian. At the end of World War I, Austria became a defeated country, and part of its territory was ceded to the victorious country. Hitler was so impressed that he had the ambition to establish the Third Reich in his mind. In order to remember the pain of the cession of his country, he changed the moustache into Rendan Hu, but in fact he imagined his beard as Rendan Hu. It can also be seen that Hitler was very original, which made him appear calm and intimidating. I don't think any celebrity with this beard has achieved his positive effect before and after his death.
