As a strategist, perhaps the best historical evaluation is exhaustive. But it's not enough to just do that, you need someone to listen to you. Otherwise, even if there is no exhaustive strategy, it is useless for no one to listen to it, and it is impossible to realize its own value. There was such a strategist in Cao Wei, who could almost be said to be exhaustive, but his opinions were always ignored and abandoned. In the end, even the jar was broken and broken, and he died of resentment. This character is Liu Ye.
<h1 class="pgc-h-arrow-right" data-track="2" > Liu Ye assisted Lujiang Taishou during Liu Xun's period</h1>
Liu Ye is a native of Huainan. In the chaotic era of the Three Kingdoms at the end of the Han Dynasty, Huainan was a relatively chaotic place. There are many rangers in the local area, including a relatively powerful one called Zheng Bao, and there are many people under his hands. Zheng Bao originally wanted to force Liu Ye to serve himself and let Liu Ye drive the people across the river. Unwilling to do so, Liu Ye set up a "Hongmen Banquet" to assassinate Zheng Bao, and then incorporated Zheng Bao's parts.
Liu Ye has courage and wisdom, but no ambition. In fact, like Liu Bei, he was also a relative of the Han Dynasty, but he did not have the idea of chasing the deer in the Central Plains, but tried to avoid being too "strong" himself. Therefore, Liu Ye handed over all the troops he received to Liu Xun, the Taishou of Lujiang. This Liu Xun had a brief performance in the late Han Dynasty when the group was competing for hegemony, and he was originally a subordinate of Yuan Shu. After the failure of Yuan Shu, many of Yuan Shu's parts defected to Liu Xun, and some of the parts that were originally intended to defect to Sun Ce were cut off by Liu Xun. So Liu Xun was once very strong.
Liu Ye did not intend to mix himself into a warlord, but he still had the intention of assisting Liu Xun. Liu Xun's strength at that time was very strong, which made Sun Ce very jealous. The other two also have old grudges. Originally, Yuan Shu promised to let Sun Ce be the Taishou of Lujiang, but in the end he gave it to Liu Xun. Sun Ce wanted to destroy Liu Xun, but Liu Xun was relatively powerful after all. So he came up with a plan to move the tiger away from the mountain, that is, to pretend to show weakness to Liu Xun and ask for favors, and to induce Liu Xun to attack Haixun Shangji. Liu Ye saw through Sun Ce's plan and persuaded Liu Xun not to win the plan, but Liu Xun did not listen, and was defeated by Sun Ce.

Liu Xun's hometown of Lujiang was conquered by Sun Ce and Zhou Yu, and he himself was pursued by Sun Ce, so he defected to Cao Cao. Liu Ye also joined the Cao Cao Group. Cao Cao still attached great importance to Liu Ye and listened to some of Liu Ye's suggestions, but unfortunately he still could not fully believe it. For example, in the 20th year of Jian'an in the Eastern Han Dynasty (i.e., 215 AD), Cao Cao defeated Zhang Lu and captured Hanzhong. This was a good opportunity to take advantage of the situation to attack Bashu and expel Liu Bei's clique. Liu Ye urged Cao Cao to continue to march south. Sima Yi and Liu Ye were one attitude. As a result, Cao Cao gave up this opportunity: "Having obtained Long, looking back at Shu Ye? The result was that Liu Bei's group was able to develop and become stronger, and after four years it seized the land of Hanzhong.
Later, Cao Cao died and Cao Pi took the throne. During the Cao Pi dynasty, Liu Ye's opinion was even more unrecognized. Liu Bei's general Meng Da surrendered to Cao Wei, and Cao Pi admired Meng Da very much, with Meng Da as the new city Taishou, and this position can be said to be the hub of Cao Wei and Shu Han and Eastern Wu. Liu Ye believed that Meng Da had two intentions and persuaded Cao Pi to beware of Meng Da. Cao Pi did not listen. Later, Meng Da did secretly defect to Zhuge Liang, but this was during the reign of Emperor Cao Rui of Wei.
At that time, Sun Quan had just captured Jingzhou, in order to avoid a two-front battle, he had to ask Cao Wei for peace, Liu Ye believed that Sun Quan was completely expedient, Cao Wei could take this opportunity to attack Eastern Wu, but Cao Pi did not listen; when the "Battle of Yiling" ended, the pressure on Shu Han suddenly decreased, and Sun Quan did not have so much respect for Cao Wei. Cao Pi planned to send troops to attack Eastern Wu, Liu Ye thought that it would be difficult to succeed in attacking Eastern Wu at this time, Cao Pi still did not listen, and launched a three-way army to attack Wu, and the result was the same as Liu Ye expected, and no decisive breakthrough was made.

Cao Pi died of illness within a few years of his reign as emperor, and Cao Rui became the second emperor of Cao Wei. At that time, there was a force in Liaodong, the Gongsun clan that had existed since the end of the Eastern Han Dynasty. Although nominally subordinate to the Eastern Han Dynasty or Cao Wei, it had a fairly independent environment. In a coup d'état within the Gongsun clan in Liaodong, Gongsun Yuan seized the position of his uncle Gongsun Gong and imprisoned Gongsun Gong. Liu Ye believed that Gongsun Yuan would rebel in the future, so it was better to take advantage of this turbulent period to attack Gongsun Yuan. Cao Rui did not accept it, and as a result, Gongsun Yuan later claimed to be the King of Yan rebelling and was destroyed by Sima Yi.
His own suggestions were not taken seriously, from Liu Xun to Cao Cao to Cao Pi and Cao Rui, missing so many opportunities, probably Liu Ye also became disheartened. In the later period, Liu Ye was no longer a wise man who calculated all the strategies, but became a sleek person who watched people's dishes. Once, when Cao Rui planned to attack Shu Han, Cao Wei's courtiers thought it was impossible. When Liu Ye and Cao Rui discussed, they said yes, and when they consulted with the Qunchen, they said no.
Once Cao Rui discussed things with a man named Yang Ji, who was firmly opposed to cutting shu. Cao Rui said to Yang Ji, "You are a scholar, how can you know about the war?" Yang Ji said that he really did not understand, but Liu Ye, the "former emperor's courtier", also said so. So Liu Ye's style was revealed. Cao Rui began to alienate Liu Ye and made him a Great Hongxu, and Liu Ye eventually died of depression.
