Who can tell me the similarities and differences between "samurai", "ninja" and "ronin"

Samurai is a social stratum specialized in martial arts in Japan, and a loyal servant of the ruling class after the middle period of heian period in Japanese feudal society. Also known as soldiers and waiters. The Wushi regimes such as Kamakura shogunate, Muromachi shogunate and Edo shogunate have been established successively (see shogunate politics). Bushido is the code of conduct of samurai moral norms. After the Meiji Restoration, it ceased to exist as a class, but its ideological system still had great influence. At first, samurai were a group of cavalry who were good at archery. They were chosen as the guards of the State Council's residence. Later, the nobles also had their own guards, warriors in the courtyard. With the further development of Japanese manor system in western Europe, emerging dignitaries began to maintain armed confrontation with the central government and local state departments in order to protect their own interests. At the beginning, the armed forces of famous teachers took blood as the core and organized domestic servants and servants into fighting groups according to the master-slave relationship. In order to ask for the protection of the famous master, underage masters and farmers also volunteered to join this group, and the master-slave relationship gradually expanded, forming a powerful samurai group. There are also samurai groups in the State Council territory outside the manor, and there are even people who have been dismissed from another group of samurai groups in the State Council. 10 ~ 12 century, many samurai groups with great political influence appeared in China, among which Qinghe Genji and Huanwu Shiping were prominent. Due to the disintegration of the central military system and local chaos, the local nobles and the emperor's court had to resort to the power of samurai to defend themselves. In the power struggle between the consorts and the royal family, the samurai took the opportunity to crowd out the forces of the state (see state politics) and the court (see court politics) and control the central government.

With the help of the Waheji Rebellion in Baoyuan (1 156, 1 159), Ping Qingsheng took part in politics with martial arts, became the minister of Zheng Tai, and took office in Liupolo, where he was stationed, creating a precedent for Japanese samurai to be in power. Soon after, the Yuan Dynasty wiped out the Ping family, appointed a general to conquer foreign countries, and established the Kamakura shogunate, from which the Wu family regime was born. The Wushi regime existed for nearly 700 years in Muromachi era, Zhifeng era and Edo era. During the Edo period, the samurai class formed a strict status hierarchy, and the martial arts reached its peak. After Meiji Restoration, the feudal identity hierarchy was abolished, and 1872 denied samurai identity. Since then, the samurai class has gradually disappeared. ? Hey? G @ #

In order to strengthen the combat effectiveness, the samurai regiment, which is linked by the master-slave relationship, requires the samurai to be loyal, brave, filial, upright and have no desire or desire, so that they can form a character of absolute obedience to the monarch, emphasizing keeping their promises, ignoring life and being brave in fighting. These requirements for samurai are called "the way to bow and horse" or "the way to life and death". Since the Kamakura shogunate, these requirements have become feudal ethics that feudal warriors must abide by in the form of laws and regulations. After the establishment of the edo shogunate, the samurai were influenced by Confucianism and believed in the five virtues and five permanents very much. Su theorized and systematized the words, deeds and beliefs of the samurai in this period and named it Bushido, and the ideological system of the samurai class was completely formed. After the Meiji Restoration, Japanese militarists embodied the spirit of Bushido in the form of loyalty to the emperor, and vigorously promoted Bushido inside and outside the army, making it an ethical concept of the whole society. With the foreign aggression and expansion of Japanese imperialism, militarists combined Bushido with fascism and formed the modern fascist Bushido spirit.

A ronin is a samurai without a master.

Japanese ronin, also known as mainland ronin, national scholar, great man, righteous thief, Ren Xia and "hero", is a unique historical phenomenon in modern Japan and a very complicated and influential social stratum in modern Japan. They are poor soldiers who wander around without their master's home. In order to restore the authority of the past, they are crazy and take risks. They pretended to be the emperor's own soldiers and appeared everywhere as "patriots". Their energy is amazing because of their skills.

From 15 to 16 100 years, the Tokugawa era existed in name only. Dozens of separatist forces have emerged in Canada, where the central government is not strong, and they have rebelled and attacked each other. Due to the limited land forces of various units, they train "special agents"-"ninjas" to carry out reconnaissance, sneak attack, assassination and other activities. Wushu is only a small part of ninja's practice. In addition, there are five compulsory subjects of "food, fragrance, medicine, qi and body", commonly known as "Ninja Five Ways".

Ninja is also an astronomer and chemist, who can observe the stars to predict the weather and make gunpowder and firearms. The martial arts of ninjas are fundamentally different from those of Japanese samurai. Because of their special tasks, ninjas usually use portable short weapons and hidden weapons instead of broadswords or spears. According to legend, there was a kind of hidden weapons in the Wulin of the Central Plains in the Ming Dynasty, named "Bajiaoling". It is made of pure steel, sharp as a knife, thin as paper, and only two inches in size. Scattered all over the floor like a rain flower, and it is highly toxic. Probably by a Japanese ninja. Ninja unarmed combat is also necessary. Fingers as steel as iron pierce the chest and abdomen, tear the neck, split the head, and instantly kill people. Although it is not as extensive and profound as the Central Plains martial arts, it is practical and fully conforms to the ideological basis of "winning with one blow" in fighting.
