What happened in Xuzhou makes people want to emigrate.

I think the reason why Liu Bei invited Sun Quanmu to Xuzhou is:

1, please take the lead in improving political treatment.

Liu Bei was a general left in the Eastern Han Dynasty Hall. He was serious, nominally an army of the Eastern Han Dynasty, especially his classmate Gongsun Zan, who made Liu Bei an official and a shepherd in Yuzhou. Therefore, although Liu Bei was a warlord, his political position in the Eastern Han Dynasty was really high. In contrast, Sun Quan is much worse.

Because he is just a general with a mixed name, compared with Liu Bei's political status, he is really a man with his head down. Therefore, after joining hands with Wu to fight against Cao Cao, Liu Bei, after becoming the heir of Liu Qi, must ask Sun Quan for advice if he wants to gain the continued trust of his allies. Therefore, he named Sun Quan, the major shareholder in the Sun-Liu Alliance, as a general riding a bicycle and herded in Xuzhou. From then on, after Yuan Qi rode in the Eastern Han Dynasty, the second person in the Eastern Han army became Sun Quan. As for the existence of Xuzhou animal husbandry, it turned Sun Taishou into a state animal husbandry. ? So that is to say, Liu Bei is saying that all the good things belong to boss Sun, and boss Sun and himself are state shepherds, but he is the second person in the Sun-Liu Alliance! Because of his high rank!

2. Contribute to the orthodox identity of Sun Quan.

What's more, at the end of the Eastern Han Dynasty, warlords were separated, but the orthodoxy of the Han family remained unchanged. Therefore, Sun Quan is uncompromising not only in Jiangnan, but also in Xuzhou, and politically, Sun Quan has two legal territories. Sun Che's orthodox position is even greater, so what will people in the Korean family think?

3. Let Sun Quan be justified and win the hearts of the people.

What's more, Sun Quan is a foreigner in Wu Dong. He took immigrants and relied on the military strength of his father and brother to crush local strongmen. Therefore, in order to better balance the local tyrants in Soochow, Sun Quan can make use of Xuzhou's herdsman status and seek more northern political forces with the help of the conquest system of the Han Dynasty to balance the expansion of local strongmen.
