What are Toyotomi Hideyoshi's Guan Bai and civilian Tiger's official positions in Tokugawa Ieyasu?

"Guan Bai" (equivalent to the position of prime minister of the imperial court, usually held by the highest-ranking aristocrat) was completed by Hideyoshi Fujiwara and Toyotomi Hideyoshi in Osaka City on 1585, that is, Hideyoshi changed his surname to Fujiwara at the age of 50 and was promoted to the position of "Guan Bai" representing the highest power of the imperial court. The post of "Guan Bai" has been monopolized by Fujiwara since ancient times, especially the guards and eagle divisions of Fujiwara family, who are called "five photographers". Therefore, Hideyoshi first recognized former Guan Bai and former Jin Wei as michel platini (Jin Wei is also a Fujiwara clan), and then he was promoted to Guan Bai. As for why Hideyoshi held the position of Guan Bai in the imperial court instead of "conquering foreign generals", although opinions were different, in fact, the generals of the Warring States at that time were moved to tears when they heard that the imperial court was going to give them a nominal position. Therefore, Xiuji's promotion to "Guan Bai" will naturally feel infinite glory. In the second year of Guan Bai's promotion (1586) and the second day of Yozei's accession to the throne, Toyotomi Hideyoshi was promoted to the highest official position under the legal system, "Minister Zheng Tai". Although Guan Bai's position represents the highest power, it still belongs to officials outside the orthodox legal system. From this perspective, Hideyoshi intends to rebuild the world order according to the official position of the legal system. On the other hand, maybe Toyotomi Hideyoshi thought Fujiwara was too old to show that he was the greatest man in history, so Toyotomi Hideyoshi got permission from the Emperor to change his surname to Toyotomi, symbolizing the birth of Japanese ruler Toyotomi Hideyoshi.
