Although Wu Sangui is under the banner of fighting against the Qing Dynasty and regaining sight, he also knows that his practice is very contemptible, because he used to be a Han thief, and he will eventually become an emperor. If you inherit the banner of Daming, you have to choose Zhu's children as the emperor, and you can only start a new stove and take Dazhou as the country name. In history, the Zhou Dynasty once had a glorious time, and Wu Zetian replaced Li Tang as the national title with the mainland, which is the best proof. But helpless, this is only superficial. Wu Sangui was still unable to compete with the Qing Dynasty in strength, so it was destroyed in just eight years.

Wu Sangui was a founding hero of the Qing Dynasty, but he was also a traitor of the Ming Dynasty. He was once hated by many Han Chinese because he led the Qing Dynasty into the customs and later personally destroyed Nanming. In this case, he gave himself a face under the banner of anti-Qing and regaining sight. Even a person who really wants to clear up the Qing Dynasty and regain his sight can hardly trust him, so he has to start over and create a new dynasty.

Historically, people spoke highly of the Zhou Dynasty, because people paid attention to the enfeoffment system at that time, and what Wu Sangui lacked most was allies. Wu Sangui made a good calculation, thinking that he could summon the governors to crusade against the Qing Dynasty, but the reality was that those forces opposed to the Qing Dynasty were not particularly strong and had no great ambitions. Besides, Wu Sangui has no advantage, so they don't like Wu Sangui.

As the king at that time, Wu Sangui's fiefs were all in the south, while the north was heavily fortified by the Qing Dynasty. Since ancient times, it has been difficult to unify the whole country from south to north. It is because of the high terrain in the north that Ma Pingchuan's northern and southern cavalry can attack and retreat, but Wu Sangui did not really unify the south and was not an opponent of Manchu for a long time.
