People are old and dim
Emperor Gaozong of the Southern Song Dynasty did the wrong thing of killing Yue Fei in his lifetime, but Emperor Gaozong of Song gave the throne to Song Xiaozong in his fifties, and then became the Emperor Taishang for more than twenty years. From a biological point of view, people will be confused at a certain age, so as an emperor, early Zen is a kind of responsibility for Jiangshan.
In stark contrast to Emperor Gaozong of Song was Sun Quan the Great.
In the chaotic era at the end of the Han Dynasty, Sun Quan was able to block the conquest of Cao Cao and Liu Bei, and he could also take the initiative to attack the Cao Pi regime, which was enough to prove that Sun Quan was a hero Haojie.
However, a wise man like Sun Quan still did something wrong in his later years: after Sun Quan's later years, he failed to effectively handle the relationship between his children, which led to the chaos of the Wu state seizing the throne, and eventually, resulting in the deposing of the crown prince Sun Quan and Sun Quan, and Sun Ba, who seized the throne with Sun Quan, was killed by Sun Quan.
Sun Quan chose to make his youngest son Sun Liangzhuan crown prince. Sun Liang was still a child when he succeeded to the throne, and in the end, Sun Liang was deposed by the powerful ministers, and the state of Wu was once again in a state of chaos.
It can be said that this is all Sun Quan's old age and faintness, which has brought a negative impact to the State of Wu.
Sun Hao ascended the throne
After Sun Quan's death, the state of Wu was in turmoil, and the throne fell into the hands of Sun Xiu, the emperor of Wu Jing.
Later in Sun Xiu's reign, Cao Wei annexed Shu Han. At that time, Cao Wei's national strength was stronger than that of Shu Han and Wu, and Shu Han and Wu needed to unite to barely protect themselves. Now that the Shu Han Dynasty had collapsed, Cao Wei was likely to enter the state of Kou Wu in a big way. This frightened Sun Xiu, and soon Sun Xiu became depressed and eventually died.
Sun Xiu's son was still young, and if Wu Guo ascended the throne, he would inevitably need auxiliary ministers, and if there was internal friction between the auxiliary ministers, it would undoubtedly give Cao Wei, who was looking at the tiger, have the opportunity to annex the state of Wu. Therefore, with the support of some ministers, Sun Hao became the Emperor of wu because of his old age.
In the early days of Sun Hao's reign, he also had remarkable political achievements: due to Cao Wei's annexation of Shu Han, the original border between Shu Han and Wu became the border between Cao Wei and Wu. Shortly thereafter, Cao Wei was replaced by the Western Jin Dynasty.
Among them, the Jiaotong area was originally the land of the Wu State, bordering the Shu Han Dynasty. After the Western Jin Dynasty took over the handover, it sent troops to capture the cross-toe. During Sun Hao's reign, in order to issue the issue of the ownership of the toe, a war broke out with the Western Jin Dynasty and recaptured the toe from the Western Jin Dynasty - it can be said that Sun Hao was quite successful in the early days of his reign.
Sun Hao's nature
As Sun Hao gradually grasped the power that the emperor deserved and succeeded in his campaign against the Western Jin Dynasty, gradually, Sun Hao began to swell:
First, the overdraft of the people's strength. On the one hand, Sun Hao built a large number of civil engineering in China and built a palace for pleasure. In addition, the state of Wu, with a population of 2.3 million, also had to feed a standing army of 230,000. And Wu Guo's financial strength cannot support this series of burdens;
Then there was the political purge. Sun Hao is the son of the wasted prince Sun He, and in the process of growing up, he was oppressed a lot, which led to Sun Hao having a perverted psychology. Therefore, after coming to power, Sun Hao was cruel, and at the same time keen on killing people, and killing people was arbitrary, and even used this to promote political purges, and in the end, under Sun Hao's tossing, the able subjects of the Wu court either died under Sun Hao's butcher's knife, or were forced by Sun Hao to surrender to the Western Jin Dynasty, or deviated from Sun Hao.
In this way, long before the Western Jin Dynasty destroyed Wu, the State of Wu had already lost its ruling foundation, and its demise was a foregone conclusion.
