History has always been very fair, since Cao Cao carried a black pot for Yuan Shao because of Zhang Miao's matter, Yuan Shao soon carried a black pot for Cao Cao because of Zang Hong's matter. And both of them have paid a heavy price for this

【Difference and Cost】

Zhang Miao as Cao Cao's old boss, old friend, the friendship between them is very deep, if it weren't for Yuan Shao, Zhang Miao would most likely not betray Cao Cao, and at that time, Zhang Miao was Chen Liutaishou, as long as he didn't move, Chen Gong and Zhang Chao basically couldn't welcome Lu Bu into Yanzhou, and Cao Cao would not end the war against Xuzhou in history, and might even take down Xuzhou in one go, eliminate Tao Qian and Liu Bei, and occupy the two large states of Yan and Xu, instead of being almost cornered by Lu Bu in the battle of Yanzhou.

And what about Yuan Shao? Yuan Shao's price paid for Zang Hong's rebellion was no less than Cao Cao's.

First of all, Yuan Shao bullied his subordinates for an outsider, what do you think other people in Yuan Shao's group will think?

And Yuan Shao was delayed for more than a year because of the Zang Hong Rebellion, what does such a long time mean? It means that if there is no Zang Hong, Yuan Shao's unification of the north may be more than a year earlier, which means that Yuan Shao may be ready to go south in the third year of Jian'an (198).

And what situation did Cao Cao Group face at that time, there was Zhang Xiu next to Xuchang, and Zhang Xiu had the support of Liu Biao behind him, and Lu Bu occupied Xuzhou, Yuan Shu owned Huainan, Cao Cao was facing enemies on all sides at this moment, if Yuan Shao went south at this point in time, it would be difficult for Cao Cao not to lose, don't forget that Lu Bu loves to take the opportunity to sneak attack other people's rear, not to mention that Yuan Shu also wants to recapture Yuzhou.

The most important thing is that Cao Cao is passive in Zhang Miao's affairs, he has no choice, but Zang Hong's affairs Yuan Shao is active and can choose, if Yuan Shao finally chooses to help Zang Hong deal with Cao Cao and rescue Zhang Chao, then it will be catastrophic for Cao Cao, who is almost exhausted after fighting with Lu Bu, and after facing Yuan Shao, Cao Cao may not have much energy to welcome the Son of Heaven later.

Yuan Shao chose to side with Cao Cao between Cao Cao and Zang Hong, but what did Cao Cao do to him later?

【The Beginning of the Break】

In the first year of Jian'an (196), Cao Cao welcomed the Son of Heaven in Xuchang and successfully controlled the imperial court in the shortest time.

Then Cao Cao directly issued an edict to Yuan Shao in the name of the imperial court, blaming Yuan Shao for having many generals but blindly caring about his own gangs, not only did not send troops to rescue the Son of Heaven, but also attacked others without authorization.

And what is Yuan Shao doing at this time?

The battle of Yanzhou between Lü Bu and Cao Cao ended in the second year of Xingping (195), when Cao Cao led an army against Zhang Chao in autumn and August, besieged Yongqiu, and broke through Yongqiu in winter and December, eliminating Zhang Chao. Subsequently, Zang Hong decided to break away from Yuan Shao because Yuan Shao did not give him reinforcements to rescue Zhang Chao, and the East County was autonomous, and Yuan Shao immediately sent a large army to attack and besiege Dongwuyang, the seat of the East County Administration, for more than a year.

That is to say, at this time, Yuan Shao should still be in the camp outside Dongwuyang City, wiping Cao Cao's buttocks, and then the Xuchang Imperial Court gave Yuan Shao such an edict, what do you think Yuan Shao will think, what can he think.

Yuan Shao called Zang Hong's fellow villager Chen Lin over at that time and asked him to write a letter of persuasion to Zang Hong immediately!

But in the face of the edict of the imperial court, Yuan Shao could not turn a blind eye, in the face of the righteousness of the imperial court, even if he knew that Cao Cao was behind the ghost, Yuan Shao had nothing to do, Yuan Shao could only defend himself, and sprinkled more than a thousand words.

And what did the Xuchang court under Cao Cao's control do later?

At that time, the imperial court appointed Yuan Shao as the captain, and also named Yuan Shao as the Marquis of Ye, which seemed to be good to Yuan Shao, and now the old Yuan family was the fifth and sixth dukes, but Cao Cao himself served as a general, and his status was still above Yuan Shao.

How can Yuan Shao endure this? Since the anti-Dong, Yuan Shao has always taken care of Cao Cao, and when Cao Cao couldn't get along in the sour jujube camp, it was Yuan Shao who took Cao Cao in; Later, it was Yuan Shao who made Cao Cao the Taishou of Dongjun, so that Cao Cao justifiably had his first piece of territory; After Cao Cao became the pastor of Yanzhou, he faced the threat of Yuan Shu, Jin Shang and others, and with Yuan Shao as the backing, he moved his base camp in Yanzhou to Juancheng, which was very close to Jizhou; In the battle of Yanzhou between Cao Cao and Lü Bu, after Cao Cao's defeat in Puyang, Yuan Shao not only allowed Cao Cao to enter Jizhou, but later gave Cao Cao the support of 5,000 soldiers.

Not to mention why Yuan Shao is spending so much time and energy to surround Dongwuyang and crusade against Zang Hong now, isn't it because of Cao Cao?

Yuan Shao has always regarded Cao Cao as his ally and his subordinate, and has always regarded Cao Cao as a brother.

Cao Cao controlled the Son of Heaven in his hands and was ready to climb on his head.

Yuan Shao was ashamed to be under Cao Cao, and said angrily at that time: "Cao Cao was about to die several times, but I saved him, and now he is going to be ungrateful and coerce the Son of Heaven to order me!" ”

So Yuan Shao deliberately wrote to Emperor Xian to resign, not accepting the position of Tai Lieutenant. At that time, although Yuan Shao had not yet been able to unify the north, Cao Cao had just welcomed the Son of Heaven, and his strength was not as good as Yuan Shao's, and he was surrounded by foreign enemies, so Cao Cao was very afraid of making enemies with Yuan Shao after knowing this, so he gave up the position of general to Yuan Shao.

In the second year of Jian'an (197), the second year of Cao Cao's welcome to the Son of Heaven, Emperor Ling sent the master craftsman Kong Rong to hold the Son of Heaven Fujie and awarded Yuan Shao the position of general, giving him bows and arrows, runes, axes and iron, and one hundred tigers, and let him take charge of the four states of Jizhou, Qingzhou, Youzhou, and Bingzhou, and Yuan Shao accepted the appointment.

After this incident, Yuan Shao was also afraid that the edict of the imperial court would always be unfavorable to him, and saw that Cao Cao had recovered the Henan region in the name of the Son of Heaven, and also obtained the annexation of the Guanzhong region, so he wanted the Son of Heaven to move closer to him, and sent someone to Cao Cao to say that Xu County was low-lying and wet, and Luoyang was broken and destroyed, and the capital should be moved to Juancheng in order to be close to the complete and abundant area.

Juancheng is Cao Cao's original base camp in Yanzhou, when Yuan Shu marched into Yanzhou, Cao Cao moved the Yanzhou administrative office, located in Dongjun, very close to Yuan Shao's Jizhou.

But this trick used by Yuan Shao, Dong Zhao had already mentioned it, and Cao Cao used this trick to successfully paralyze Yang Feng, and finally seized Emperor Xian from his hands. Maybe Yuan Shao just wanted to restrict Cao Cao with this, and didn't want him to use the Son of Heaven against him, but these were the same for Cao Cao.

Why did Cao Cao have to move the capital to Xuchang, instead of his original base camp Juancheng, nor somewhere in Yanzhou, one of the very important reasons was that he wanted to stay away from Yuan Shao.

The relationship between Yuan Shao and Cao Cao has broken down after these things, and after Cao Cao welcomed the Son of Heaven, his prestige has been greatly enhanced, and now Cao Cao is no longer Yuan Shao's original subordinate and ally, and Cao Cao has become a threat that Yuan Shao cannot ignore.

They are already beginning to be enemies.

ps: Yuan Shao beat Zang Hong----- he is not a person inside and out. In the matter of Zang Hong, from Yuan Shao's point of view, Yuan Shao really fed his conscience to the white-eyed wolf, first Zang Hong, an ungrateful guy, let him be the assassin of Qingzhou and the Taishou of Dongjun, but for the sake of the old master, he ignored the interests of the current monarch Yuan Shao, and then looked at Cao Cao, okay, Yuan Shao beat Zang Hong for him, but he took the opportunity to seize the Son of Heaven, and then dealt with himself with the power of the Son of Heaven, it was a large version of the white-eyed wolf, Yuan Shao looked at these two guys and cried.
