Zhao Yun is ambitious and devoted himself to the people with lofty ideals he recognizes. Zhaoyun was originally from Changshan County and was under the jurisdiction of Yuan Shao. At that time, Yuan Shao was competing with Gongsun Zan for important positions. As a result, Gongsun Zan lost more and won less, which led many talents to go to Yuan Shao camp. Zhao Yun disagreed and still took people to Gongsun Zan. Gongsun Zan was very suspicious of the purpose of Zhao Yun's defection and asked Zhao Yun, "Are you an undercover sent by Yuan Shao?" Zhao Yun explained: "The world is in chaos. I don't know where to go, so I decided to go to politics. I think Gongsun Zan is much better than Yuan Shao. " Visible zhaoyun had defected to Gongsun Zan just for the benevolent government in his heart, and later defected to Liu Bei because zhaoyun thought Liu Bei was the real democratic leader of benevolent government in his heart. Gongsun Zan also knows what Zhao Yun is thinking, so he can't force Zhao Yun to leave.
Zhaoyun stayed beside Gongsun Zan for a long time, and finally saw through that Gongsun Zan was too belligerent to listen to the people around him. He is a wayward person, and he is not a democrat as he thinks. Gongsun Zan only thinks that Zhao Yun is a martial arts Iliad, not a general who can be good at fighting, so he has never reused Zhao Yun. Zhao Yungang didn't know Gongsun Zan's idea at first, so he followed Gongsun Zan to crusade everywhere, but didn't give Zhao Yunyou any chance to show. Zhao Yun gradually understood his position in Gongsun Zan's heart. Later, Gongsun Zan confronted Yuan Shao, and Tian Ji was sent to occupy Shandong. Worried that Yuan Shao was going to compete, he asked Liu Bei to help Tian Ji. At this time, Zhao was in charge of the cavalry for Liu Bei. When Liu Bei saw Zhao Yun, he thought Zhao Yun was a general, so it was a pity to bury him. Liu Bei's words made Zhao Yun admire Liu Bei even higher, and also laid the groundwork for Liu Bei's later defection.
The relationship between Gongsun Zan and Liu Bei is good, which is also an important reason why Gongsun Zan will let Zhao Yun follow Liu Bei. Gongsun Zan and Liu Bei are both disciples of Lu Zhi, and they have the same friendship. They met Liu Bei and others who defected in Gongsun Zan. They not only welcomed Liu Bei and others into the house politely, but also paid more attention to them, which shows how good their relationship is. Gongsun Zan once recommended Liu Bei's achievements to the imperial court, and promoted Liu Bei as Sima of other departments. Liu Bei is grateful for this. It was because Gongsun Zan had a good relationship with Liu Bei that he promised Liu Bei to borrow Zhao Yun and his military forces, and he was not worried about whether Liu Bei would return them.
When Zhao Yun defected to Liu Bei, it was several years after he left Gongsun Zan. Because of his brother's death, Zhao Yun had to leave Gongsun Zan for home. At this point, zhaoyun has no ownership. Later, Liu Bei fell in Xuzhou and had to run to Yuan Shao's territory. In Yecheng, Liu Bei and Zhao Yun met again. Zhao Yunben thought that Liu Bei was the wise Lord who represented benevolent government in his heart. Coupled with Liu Bei's kind invitation, Zhao Yun began to follow Liu Bei's expedition to the north and made great contributions to Shu.
Gongsun Zan makes his own decisions and only trusts his relatives. Although he knew Zhao Yun was an Iliad, he didn't trust him, which made Zhao Yun still unknown. After seeing Liu Bei, Zhao Yun thought that Liu Bei was the democratic leader he wanted to follow, but he was from Gongsun Zan at that time, so he couldn't go to Liu Bei publicly, so he had to appreciate each other. This is also the reason why Zhao Yun followed Liu Bei without hesitation when he met Liu Bei again.
Gongsun Zan was defeated by Yuan Shao and eventually set himself on fire. After Zhao Yun followed Liu Bei, he was reused, so that his talents could be fully displayed, and he occupied a place among the war generals in Shu, leaving a good name as a "perfect military commander". Visible, zhaoyun left Gongsun Zan, defected to liu bei, the democratic master, is a very correct choice.
