In order to resist Zhang Lu, Liu Zhang invited Liu Bei, the same emperor, to enter the river. Sun Quan saw that there was an opportunity to take advantage of it, so he prepared to take the opportunity to retake Jingzhou. However, Wu Guo was too afraid that sun Liu would be affected by his daughter after he rebelled, so he resolutely disagreed with Sun Quan's army. Sun Quan was a filial son, and had to agree on the spot. When Zhang Zhao saw this, he gave Sun Quan an idea, asking him to send his confidants to Jingzhou, falsely claiming that Wu Guo was too ill, and asking Sun Shangxiang to take Ah Dou back to Eastern Wu to visit his mother, and then use Ah Dou as a hostage to force Liu Bei to return to Jingzhou. Sun Quan thought it was a good idea, so he entrusted the matter to Zhou Shan.
Lady Sun heard that her mother was critically ill and hurriedly took Ah Dou and her entourage to follow Zhou Shan across the river by boat. If Ah Dou really fell into the hands of Sun Quan, I am afraid that Liu Bei would only be able to exchange Jingzhou for it. Just at this moment, Zhao Yun got the news and drove a small boat to catch up, where is zhou Shan's gang of people Zhao Yun's opponents? He boarded the big ship without much effort and asked Sun Shangxiang to leave Ah Dou behind. However, Lady Sun was very rude to Zhao Yun, and Zhao Yun had no choice but to use force to snatch Ah Dou over.
Lady Sun asked the maid to take the child, but everyone was afraid of Zhao Yun's bravery, and no one dared to come forward. Zhou Shan saw the situation, personally took the helm, and drove a large boat to Jiangdong. If he really arrived in Jiangdong, even if Zhao Yun was brave, I am afraid he would not be able to save Ah Dou. Zhao Yun could have killed Zhou Shan and forced the ship to stop, but he did not dare to do so. Soon after, Zhang Fei chased after him, and after he jumped on the big boat, without saying a word, he killed Zhou Shan with a sword.
So the question is, why didn't Zhao Yun dare to move Zhou Shan in the slightest, but Zhang Fei killed him without scruples? To answer this question, we must start from the relationship between the two and Liu Bei. Zhang Fei started a business with Liu Bei, and married in Taoyuan, the brotherly feelings are very deep, just like a family, he can represent Liu Bei at the critical moment. Zhao Yun is different, he joined the company halfway, although Liu Bei attaches great importance to him, but the two are ultimately a monarch-vassal relationship, he cannot represent Liu Bei.
Zhou Shan was an emissary sent by Sun Quan, and killing Zhou Shan meant making enemies with Eastern Wu, a responsibility that Zhao Yun could not afford. But Zhang Fei dared to do so, because he could represent Liu Bei. This can also be proved from Sun Shangxiang's attitude toward the two, Zhao Yun was very respectful to Sun Shangxiang after boarding the ship, but Sun Shangxiang did not buy it, calling him "a wufu under the account", and said that taking the child across the river is my family affair, and you are not responsible (Ru is just a wufu under the account, and an dare to take care of my family affairs!). This sentence pointed out Zhao Yun's position in Sun Shangxiang's eyes, and also explained the reason why he did not dare to kill Zhou Shan. After Zhang Fei killed Zhou Shan, Sun Shangxiang only said one sentence: "Why is uncle rude?" It can be seen from this that in Sun Shangxiang's eyes, Zhang Fei is his own family, and Zhao Yun is just a martial artist under the account. This is also the reason why Zhang Fei dared to kill Zhou Shan and Zhao Yun did not dare to kill.
