After Liu Yu succeeded in pacifying the barbarians and suppressing the rebellion of Zhang Ju and Zhang Chun, he began to give favors extensively.

However, because Youzhou is located in a remote area and needs to fight against barbarians, it costs a lot of money and food, and it often has to cut more than 200 million taxes from Qingdao and Hebei every year to supplement its supply. After Dong Zhuo's rebellion, because of the war and the cut off of transportation, it was no longer possible to dispatch money.

Therefore, Liu Yu subdued the foreign tribes to the outside world, implemented an open policy, opened up the trade between the Shanggu and the Hu people, encouraged agricultural production internally, and mined the salt and iron ore in Yuyang to obtain income.

Under Liu Yu's leniency policy, the life of the people of Youzhou gradually improved, and the people were very happy and convinced of Liu Yu's management, when Youzhou had a bumper grain harvest, and the grain was only 30 yuan per stone, and at the same time in Luoyang, Chang'an and other places under the rule of Dong Zhuo, the price of grain has been as high as a stone of grain to cost tens of thousands of dollars.

Later, the gentry and people of Qingzhou and Xuzhou also ran to Youzhou to escape the difficulty of the Yellow Turban, and it is recorded that more than one million people came to Liu Yu, and they were eventually taken in by Liu Yu and arranged for a living.

In history, although Liu Yu was the top prince, he was frugal by nature, wearing rags and straw sandals, and there were no meat dishes for a meal.

To put it bluntly, under the management of Youzhou Mu Liu Yu, Youzhou at that time had become a paradise-like existence in the troubled times of the late Han Dynasty.

It is a pity that under the thriving environment of Youzhou, the contradictions are gradually revealed. At the beginning, the imperial court ordered Gongsun Zan to crusade against Wuhuan and was commanded by Liu Yu. But Gongsun Chan was only bent on expanding his power, and indulged his subordinates and harassed the people, while Liu Yu was benevolent and always wanted to benefit the people, so he and Gongsun Chan gradually became discordant.

The gap between the two of them in terms of their views on foreign races is also very huge, Liu Yu advocates appeasement, while Gongsun Chan is a main battle faction through and through.

Gongsun Chan grew up in Youzhou, he experienced many foreign invasions, plundering and killing, and later became a general and fought with the Wuhuan people many times, many friends and subordinates around him died because of this, he and those foreigners have an indelible blood feud, in order to defend themselves, Gongsun Chan believes in the swords and guns in his hands, so Gongsun Chan takes the development of military strength as the first and belongs to the complete martial arts faction.

Compared with Gongsun Zhan, Liu Yu is much more politically mature. Liu Yu has undergone many experiences in the local and central governments, and has served as the assassin of Youzhou before, so he has a deeper understanding of the situation in Youzhou. At that time, although Youzhou was located in the north of the country, we know that the place was actually not bad at all, and several central dynasties in the later period sent the national capital there.

Therefore, the crux of Youzhou lies in the connection with the northern Wuhuan, Xiongnu, Xianbei, Fuyu, filthy and other foreign races, due to the frequent invasion of these Hu people, Youzhou can not carry out normal production, which is the fundamental reason for Youzhou's economic backwardness.

Therefore, in order to revitalize Youzhou, it is necessary to solve the problem of foreign races, but in the final analysis, the reason why the northern alien races invade is also a need for life. Because the northern barbarians are far behind the Han people in the south in terms of productivity, they have a great demand for Han resources in life, and they themselves cannot make up for it, so they have to seize it by force.

And this problem Liu Yu relied on his strong prestige to solve it very successfully, after he subdued the Hu people in the north, at the same time to give favors, open up the Shanggu and Hu people trade, not only solved the Hu people's demand for living materials, but also greatly increased the income of Youzhou.

But Liu Yu can subdue foreign races, but it does not mean that he can suppress Gongsun Zhan.

Gongsun Zhan himself is an ambitious person, and after Liu Yu became the pastor of Youzhou, he began to regard Liu Yu as a threat to himself, and even did not hesitate to rob and kill the envoys of the Hu people, putting his personal interests above the safety of the entire Youzhou.

Later, Dong Zhuo promoted Liu Yu to the Great Sima and at the same time took Gongsun Zan as the general of Fenwu and named the Marquis of Ji to balance Liu Yu.

After Liu Yu directly rejected the support of Han Fu and Yuan Shao, he was worried about the imperial court at that time, so he chose to send Peng Youbei Pingtian Chou and engaged in Xian Yuyin's adventure to go to Chang'an secretly. Emperor Xian wanted to return to the east for a long time, and he was very happy to see Tian Chou and others. At that time, Liu Yu's son Liu He served as a servant, so he sent Liu He to sneak out of Wuguan and asked him to inform Liu Yu to lead the troops to take over and welcome Emperor Xian back to Luoyang.

Liu He passed through Nanyang halfway and told Yuan Shu about this matter, but was directly detained by Yuan Shu with ulterior motives, and Yuan Shu sent another envoy to tell Liu Yu that he wanted to send troops west together. Liu Yu sent thousands of cavalry to pick up Liu He and go to the Son of Heaven together, but Yuan Shu actually refused to let Liu He go.

When Gongsun Chan knew about this, he thought that Yuan Shu was treacherous. After all, if Yuan Shu was going to crusade against Dong Zhuo with Liu Yu and welcome back the Son of Heaven, he only needed to send an envoy to come with Liu He, and there was no need to leave Liu He behind. Therefore, Gongsun Zhan repeatedly advised Liu Yu not to send troops, but Liu Yu's beloved son did not listen at all.

Gongsun Zan was afraid that Yuan Shu would know about his dissuasion of Liu Yu from sending troops and he would resent him, so he also sent his cousin Gongsun Yue to lead thousands of cavalry to Yuan Shu in order to make friends with Yuan Shao, and secretly asked Yuan Shu to arrest Liu He and seize his military power.

But this matter was known to Liu Yu, and Yuan Shu detained Liu He again, and the rift between Liu Yu and Gongsun Zhan deepened. Liu He later secretly escaped from Yuan Shu, but was detained by Yuan Shao again when he passed through Jizhou.

Gongsun Chan didn't want to succumb to Liu Yu, but Liu Yu's prestige in Youzhou was too high, so he had no choice but to start looking for another way. At that time, Yuan Shao contacted Gongsun Chan and hoped to conspire with him in Han Fu's Jizhou, Gongsun Chan hit it off, and immediately led his army south in the name of crusading against Dong Zhuo, preparing to eliminate Han Fu, seize Jizhou, and defeat Han Fu in Anping.

But Gongsun Zhan's efforts finally made a wedding dress for Yuan Shao, and Han Fu chose to give in under the strong military pressure of Gongsun Chan and Yuan Shao, and gave Jizhou to Yuan Shao, and Gongsun Chan didn't get anything.

Later, Gongsun Zhan's cousin Gongsun Yue died in battle because of the attack on Zhou Ang, the assassin of Yuzhou appointed by Yuan Shao, and Gongsun Chan gradually turned the spearhead to Yuan Shao, but at that time, the Yellow Turban Army of Qingzhou and Xuzhou rebelled, and Qingzhou Assassin Shi Jiaohe died of illness, and Gongsun Chan took Qingzhou as his target.

After two major battles, Gongsun Chan basically expelled or eliminated the Yellow Turban Army in Qingzhou and Xuzhou, and the morale of Gongsun Chan's army was also greatly prosperous, and Gongsun Chan simply took the opportunity to crusade against Yuan Shao and seize Jizhou.
