Basic introduction Chinese name: Yusanjia mbth: ごさんけ From: Japanese Edo era interpretation: refers to Tokugawa Ieyasu's historical background, initial meaning, anecdotes, meaning extension, politics and industry, idol field, Pokemon field, seiyuu field, self-work and historical background. Later historians called it "Tokugawa shogunate". In order to consolidate his political power, Tokugawa Ieyasu, like the previous shogunate, divided the names of various places in Japan into three grades according to the close relationship with the Tokugawa family. The closest name is related to the Tokugawa family. He sealed the land near Edo as his own kin, which was called "the name of pro-vassal". Among them, Tokugawa Ieyasu's nine men, Tokugawa Yoshinobu, ten men, Tokugawa Laixuan and eleven men, Tokugawa Laifang, are close relatives, collectively known as the "Imperial Three Houses". If the general has no children, he will choose a suitable object from the "three royal families" and adopt him as an adopted son to inherit the position of the general. The three imperial families, the Tokugawa shogunate, were written in the middle of the imperial clan, and the fiefs were in Jiyi (Tokugawa to announce), Mito (Tokugawa to come), and Zhang Wei (Tokugawa to rule), which were called the Yoshino Tokugawa family, the Mitokawa family and the Weidokawa family. Tokugawa surnames and Tokugawa family emblems with three-leaf sunflower patterns are allowed (but only for governors. Three-leaf sunflower has some differences, such as "Tail-extended three-leaf sunflower" (Shuang Ye table sunflower), "Jizhou three-leaf sunflower" (one-leaf table sunflower) and "Mito three-leaf sunflower" (three-leaf back sunflower). If the general has no children, the heir is chosen from the three royal families. At first, the meaning was accurate. Tokugawa Ieyasu, the first royal family, designated the general family, Jizhou family and Wei Zhangjia family. The Mito family has been deputy generals for generations, responsible for impeaching the general's misconduct and communicating with the court. When the general's family dies, it is up to the Mito family to decide who will inherit the inheritance. But in the later evolution, the Mito family joined the Yusan family. The "Three Series of Tokugawa Empire" was founded by Tianhai. It is generally believed that Tokugawa family, Tokugawa family and Weidechuan family are separated from Tokugawa family. When the tribe has no heirs, they are welcomed as adopted sons and inherit the generals from Yusan tribe. In fact, the "Imperial Three Houses" refer to the Tokugawa Sect, the Tokugawa Family and the Wei Tokugawa Family. As an exception, the "Tokugawa Family" is absolutely forbidden to marry an adopted son, but it is allowed to enjoy higher rights as a "deputy general" (such as the famous Huangmen). There is a reason for this. Edo Francisco is located in the "ghost gate" in the northeast of Edo. If there is an attack on the death gate of Edo, from the perspective of divine power (it should be the luck of Yin and Yang Feng Shui), it will cause the danger of the demise of the shogunate. In order to prevent this from happening, Tianhai asked a Tokugawa family to move to Mitofan and forbade them to welcome their adopted son from Mitofan. This is taboo. The entrance to the Ghost Gate is for evil spirits. From a magical point of view, this is related to the Tokugawa shogunate. Coincidentally, Tokugawa Yoshinobu, the last general of the Tokugawa family, was born in Mitokawa (he adopted the Tokugawa Ichibashi family at the age of 9), which brought a mysterious color to the decline of the Tokugawa family.
