First, the wizards discovered by Zhuge Liang
After Liu Bei took Yizhou from Liu Zhang's hands, he became ethereal, according to the Chronicle of the Three Kingdoms: (Liu Bei) and Bacheng, the soldiers all gave up their work and went to Tibet to compete for treasures... And "Huayang Guozhi" is more straightforward: the wine assembly, the food of the three armies. Take the gold and silver of the people in Shu City and award them to the soldiers...
It was also in this situation that Zhao Yun used the example of "why did the Xiongnu not perish and become a family" first show his attitude, and then advised Liu Bei: The world has not yet reached the time of song and dance, we must not be so oblivious, but also should struggle!

It is conceivable that Liu Beidu did this, and the other ministers under him could only be more crazy, such as Li Yan was also engaged in relocation and building luxurious residences, etc., but at this time, one of his small officials also stood up to stop Liu Bei like Zhao Yun, but unfortunately Li Yan did not listen, so this small official submitted his resignation in a huff, saying: I will not do it! This person is Yang Hong!
Yang Hong is an "unpopular" figure of Shu Han, not many people know it, but he can be called a Shu Han wizard. Because he was not interested in the knowledge in books since he was a child, naturally this affected his career path, so he was first under Li Yan and later discovered by Zhuge Liang.
2. Help Liu Bei defeat Cao Cao and take Hanzhong
When Liu Bei attacked Hanzhong with Fazheng and Huang Zhong and launched the Great Battle of Hanzhong with Cao Cao, everyone knew that this "Great Battle of Hanzhong" was fought for a long time and caused great difficulties to both Cao Cao and Liu Bei, and this was the supply of the rear. So much so that Liu Bei was anxious, and wrote a letter urging Zhuge Liang, who was sitting in Chengdu, to hurry up and find a way.
Zhuge Liang was also anxious now, and he felt a little helpless, so he asked Yang Hong and asked him to talk about his views, so Yang Hong said: "Hanzhong has been the throat of Yizhou since ancient times, and it is necessary for the boss Liu Bei to take Hanzhong to fight Cao Cao." Therefore, at this moment, we should fight together regardless of men and women, so as to solve the immediate crisis. ”
Without saying a word, Zhuge Liang asked Yang Hong to take charge of the logistics of Hanzhong and recommended him to be the Taishou of Shu County. Facts have proved that Zhuge Liang's vision is very accurate, and it is under Yang Hong's dispatch that Liu Bei can finally defeat Cao Cao and take Hanzhong in one fell swoop. Therefore, the so-called "bad learning" of Yang Hong in history is actually not like to read dead books, or dead books.
Let's say that the strategy he gave to "support the front line together without asking men and women" was quite a bold method in ancient times, and it can be said that it was an innovation, and if people who were dead readers, I am afraid that they would not have such courage. But Yang Hong can break through the convention, so this can only be used as a "wizard" to locate him.
It was also because of Yang Hong's outstanding performance that after Liu Bei captured Hanzhong, Li Kui officially appointed him as the Taishou of Shu Commandery. It should be noted that this official position was originally held by The Red Man Fazheng in front of Liu Bei's eyes, and was an important position in Shu Han. It can be seen that Yang Hong's talent has not only been recognized by Zhuge Liang, but Liu Bei is also very satisfied.
But what neither Liu Bei nor Zhuge Liang could imagine was that it was this normal appointment that inadvertently saved Shu Han and made Shu Han survive the most dangerous period.
Third, save shu han
Soon after taking Hanzhong, Guan Yu launched the Battle of Xiangfan, and with Guan Yu's defeat and killing, Liu Bei, after claiming the title of emperor, desperately launched the "Battle of Yiling" against Eastern Wu, but unfortunately he was still defeated, Liu Bei retreated to Yong'an, and then the famous "White Emperor City Trust" incident occurred.
But just when Liu Bei was entrusting Zhuge Liang with loneliness, something big happened to Shu Han. Han Jia Taishou Huang Yuan heard that Liu Bei was going to die of illness, and Zhuge Liang was not in Chengdu, and after going to the White Emperor's City, he raised an army to rebel! This news was a thunderbolt on a sunny day for the Shu Han at that time.
Because there were not many soldiers and horses in Chengdu at that time, and what was even more fatal was that the two main bones of the Shu and Han Dynasties were all in the White Emperor City, and they did not know that this happened in the rear, so at that time, Chengdu was in a panic, Liu Chan was also helpless, everyone understood that if Huang Yuan's rebellion was not suppressed in time, would it trigger a chain reaction?
If the situation develops to such a point, even if Zhuge Liang returns, I am afraid there will not be a very good way. Just at the moment of this thousand guns, Yang Hong stood up and found Liu Chan: "Now you can only use the prince's own soldiers." And analyzing the current situation, Yang Hong believed that Huang Yuan would not attack Chengdu, and he was also afraid that if Liu Bei did not die, he would lead his troops to kill him. Therefore, Huang Yuan has only one way, that is, to go down the river east to join Eastern Wu. Therefore, two generals, Chen Xuan and Zheng Qi, should be sent to lead their troops to guard the mouth of the Nan'an Gorge.
Sure enough, Yang Hong was right, it was at the mouth of the Nan'an Gorge that Huang Yuan was captured, and he very quickly suppressed this rebellion, did not cause a major disaster, and saved Shu Han in one fell swoop. Both Zhuge Liang and Liu Chan were very pleased to hear about it, especially Zhuge Liang, who could best understand how dangerous the situation of Shu Han was at that time. Therefore, Yang Hong was subsequently given the title of "Marquis of Guannei" and became a person zhuge liang relied on from then on.
Unfortunately, although Yang Hong had a genius, in 228 AD, that is, only five years after Liu Bei's death, Yang Hong also died of illness. And this year is also the time of Zhuge Liang's first Northern Expedition, it can be assumed that if Yang Hong had not died of illness, with his talents, he would have become Zhuge Liang's right and left arm, so Yang Hong's death can be called a major loss to Shu Han.
