In history, Sun Quan attacked Hefei five times, and Zhuge Ke attacked Hefei once. In the end, two big defeats and four times without results. It can only be said that Sun Quan is inferior to Sun Ce.
In 200, at the Battle of Guandu, Liu Fu served as the Assassin of Yangzhou, built Hefei, and strengthened the defense.
In 208, after the Battle of Chibi, Sun Quan attacked Hefei and was unable to conquer it. Liu Fu stayed in Hefei for eight years, so that Eastern Wu could never conquer Hefei. Eight years ago, Sun Ce did not die, and should have easily captured Hefei. It was because of Sun Ce's death that Cao Cao was able to unify the north and Liu Bei to rise.
In 215, after the demarcation of the Xiangshui River, Sun Quan led 100,000 troops and attacked Hefei again, but was twice destroyed by the Wei general Zhang Liao. The inability of wu to capture Hefei shows that its military strength is weak. Zhang Liao broke Eastern Wu twice, but he was not as famous as Guan Yu.
In 253, Zhuge Ke led 200,000 troops to attack Hefei, losing his troops. During the Three Kingdoms period, there didn't seem to be many top players. The State of Zhao had Li Mu, the State of Qin had Bai Qi, Liu Bang had Han Xin, and the three kingdoms had Deng Ai. In terms of battle achievements, Deng Ai and Zhang Liao are still OK. The Western Jin Dynasty destroyed Wu, because of its strong military strength, it was able to destroy the Decay.
In 207, the Battle of White Wolf Mountain, Zhang Liao broke the Wuhuan. In the Tang Dynasty, Xu Yanbo compared Zhang Liao to Wei Qing and Huo Fuyi.
In 209, the Battle of Tianzhu Mountain, Zhang Liao broke Chen Lan, false festival. If Zhang Liao replaced Cao Ren, it is estimated that it will not be Yu Ban's turn to send Guan Yu a reputation.
