Qiuyue family is an aristocratic family that established Su Yi on the eve of Kamakura shogunate era. Together with Harada and Gao Qiao, they are called "the three great clansmen of the Dazang family". It is said that the great collectors are descendants of the last Emperor Wu of the Han Dynasty in China. According to the Records of the Historian, Japanese minister Heji was the one who traveled to Japan at the end of the Han Dynasty. During the Japanese court era, he was responsible for collecting official articles and held a position called Dazang. Of course, there is another saying. Some people think it's because they live in the Tibetan Valley of Peking University. This Tibetan language is not named after an official name, but after a place name. In the fourth year of Tianqing (94 1), the West Sea riot launched by Iraq against Junyou Fujiwara was also the "Tianqing Rebellion" in history. In fact, Da Zangchun joined the army led by Xiao Ye Gu Hao. Because of his meritorious service in quelling the rebellion, he was enfeoffed to the front line of Jiuzhou, worked in Taizai Prefecture, and built the defense system of Kitakyushu. The original stream of the great collectors was Harada's, and later it was divided into Qiuyue, Gao Qiao, Tianqi, Jiang Shang, Sanyuan, Shang Di and Koganamaru. Then, what is the word "twist" of Nishida and Harada, which come down in one continuous line? The word "Jin" is generally regarded as the common word of their two families. During the Warring States period, the Dazang family was the retainer of the Dainei family and the Judas family successively.
