Who Ruled the Sui and Tang Dynasties

In 580 AD, three wells in Chang'an City froze and cracked. A middle-aged man named Yang Jian walked into the palace and said one word to the five princes: "Kneel down." The Great Zhou Dynasty was gone, and the Great Sui Dynasty came. In 705 AD, a woman sat on the dragon throne in Luoyang City. She was sick, very sick, but no one in the world dared to move the throne one foot away before she closed her eyes. During these one hundred and twenty-four years, four country titles were changed, more than a dozen emperors died, and dozens of wars were fought. But if you read the history books, you will find a strange phenomenon - no matter who sits on that chair, it is always the same group of people who speak effectively in the court. Their surnames are Yang, Li, Dugu, Yuwen, Changsun and Wu. They are the Guanlong Group, a wealthy club tied together by military merit and marriage. Yang Jian was pushed up by them. They pulled Yang Guang down. Li Yuan was helped up by them. Li Shimin was tied to them. Wu Zetian was the woman who kicked their card table over. This book does not talk about the great achievements of emperors and generals, but only talks about a simple question: Who is the real boss of the Sui and Tang empires? Open it and you will find that history is stranger than fiction. Those you think are heroes are full of calculations at heart. Those fools you think are wiser than anyone else. This is a power game that has lasted for a hundred years. There are no good guys, no bad guys, just a bunch of people who don't want to get out of the poker table.
