What is the origin of Japanese ronin?

In Japan, ronin originated in Kamakura shogunate era, referring to those down and out warriors who lost their seals and left their masters' homes to wander around. 1868, the mufan system collapsed, and once there were as many as 65438+ million ronins. After the Meiji Restoration, some ronin were used by the Japanese army as pioneers of Japanese aggression and expansion. From now on, ronin has become synonymous with homeless people who do nothing and make trouble everywhere. After Japan replaced Germany to occupy Qingdao, in order to consolidate its rule, it has always taken Qingdao as its own and formulated immigration policies. Among the tens of thousands of Japanese immigrants in Qingdao, many are Japanese ronins who are not welcome in Japan. China calls them Japanese ronin. Even after China recovered Qingdao's sovereignty, the Japanese ronin still committed crimes. They commit murder and arson, smuggle firearms, sell drugs, rape women, and counterfeit money.
