Because beards are difficult to grow and difficult to shave, this It has something in common with the Japanese Bushido, so it is regarded as precious and only a small square handful in the middle is kept. Because that style of beard is easy to clean and comb daily, and long beards will not fall into the rice when eating, it is called "hygienic beard". And because the shape is similar to the scrub brush used for laundry, it is also called "scrubber brush Hu".
The popularity of this kind of beard reached its peak in Germany and Japan during World War II, and almost men of certain ages would wear beards. Hitler, the German Nazi leader, kept this kind of thing. Not only Germans, but also Japanese and Soviet generals, such as Voroshilov, and Chiang Kai-shek seemed to have had such beards.
