In Chinese history, the emergence of a famous monarch can change the situation in the world, and a good heir can change history. The emperor is not God, and without us having a God perspective, we can see the advantages and disadvantages of the heir to the throne, and we cannot see the direction of history.
Let's see who lost the throne and could change history if they succeeded.
Fusu:
The eldest son of Qin Shi Huang, he was resolute and courageous, and believed in people and fought hard. He is lenient, politically far-sighted, and outspoken and exhortative. Due to the influence of Confucian culture, he had a disagreement with Qin Shi Huang, who believed in the Dharma, and was arranged to go to northern Xinjiang to fight with Meng Tian to resist the Xiongnu. Qin Shi Huang died suddenly, and Zhao Gao conspired with Li Si to give Death to Fu Su and pay Hu Hai to become Qin II. If Fu Su ascends the throne, the Great Qin Empire may be able to recuperate and reconcile with the remnants of the Six Kingdoms, and the Qin Dynasty can be passed on for hundreds of years.
Cao Zhi:
Cao Cao's third son, who was only eight years old, if he won the victory with Cao Pi, he might be able to return to the Han Dynasty, and Sima Yi, Chen Qun and other family door valves would not gain power. Cao Zhi and his descendants would not have a short life, and Sima Yi's father and son would not have the opportunity to usurp power.
Sima You:
The second son of Sima Zhao, Emperor Wen of Jin, the stepson of Sima Shi, and the half-brother of Sima Yan, Emperor Wu of Jin. Sima You was gentle and intelligent, had a ability to govern, and was quite accomplished in his position. In Emperor Wu's later years, there were high calls for Sima You's succession inside and outside the imperial court, and the ministers Xun Xun and Feng Zhen took the opportunity to expel him from the court, causing Sima You to hate the disease and vomit blood and die, only thirty-six years old. If Sima You had taken the throne, sima Yan would not have been so dimwitted in his later years, nor would he have passed the throne to the fool Sima Zheng, and the rebellion of the Eight Kings might have been avoided.
Yang Yong:
The eldest son of Emperor Wen of Sui, he was handsome and learned, wide and frank. If he can become The Sui II, not necessarily like Yang Guang to establish a great deed, rush to dig a canal, build Luoyang, conquer Goryeo, and fight against the steppe nomads, Yang Yong's ascension to the throne can be done without tossing and turning, and can maintain the continuation of the Sui Dynasty.
Li Jiancheng:
The first generation of princes of the Tang Dynasty, if it were not for Li Shimin's killing and smooth ascension to the throne, could also reach Li Shimin's prosperity, and Wu Zetian would not have a chance.
Li Ke was on the throne, and there was nothing wrong with Wu Zetian.
