Historians' evaluation of Tang Ruizong Li Dan is this: he is confused in small things, smart in big things, and wise enough to understand the benefits and righteousness of self-defense. But there are no guarantees in the late festival, and it is easy to be confused by others. The life of Li Dan, Ruizong of the Tang Dynasty, was ill-fated, but he was always helped by noble people and used his great wisdom to avoid life dangers again and again. Conspiracy, Tang Ruizong Li Dan may not be a good emperor, but he can be said to be an upright person. Ruizhong was born with the title of prince and later became emperor twice. Such an experience can only be compared to his compatriot Emperor Zhongzong of the Tang Dynasty.

However, as a member of the Li Tang royal family, as an heir (alternative heir to the throne) like him, he was proposed to be the emperor's younger brother and the emperor, but there was no second person. Not only that, among all emperors, it is not uncommon to have an emperor's father, but there are also many who have an emperor's mother. The only two brothers in history whose parents became emperors were Ruizong and Zhongzong. What was even more different about Ruizong was that his three brothers (all born to Wu Zetian) were established as crown princes, and the two older ones failed to ascend the throne.

The eldest son among his own sons also had no chance of becoming emperor. In the end, Sanlang succeeded the emperor, namely Xuanzong Li Longji. In that troubled time when the clan often encountered disasters, Ruizong could protect himself and die well.

The emperor (Ruizhong) respectfully retreated to avoid disaster. ?. This clearly shows that Turbine Sect is indeed superior.
