Was the real Guan Yu in history as heroic as described in Romance of the Three Kingdoms?

In history, Guan Yu was indeed a very famous general, but in the Romance of the Three Kingdoms, his description was exaggerated. Although Guan Yu performed well in the war, his actions were also controversial. Guan Yu performed well during the Three Kingdoms period because he was a loyal general who had served Liu Bei many times and protected Liu Bei's son, Liu Chan. He had even performed outstandingly in the Battle of Red Cliff, defeating Sun Quan's army. However, the description of Guan Yu in Romance of the Three Kingdoms was also exaggerated. In the novel, Guan Yu was portrayed as an extremely brave general who could single-handedly defeat powerful enemies. Such a description might mislead people into thinking that Guan Yu was invincible in reality. Although Guan Yu performed well in the war, his actions were also controversial. We should understand Guan Yu's true image through historical records and archaeological research, not judge whether he was really invincible based on the description of novels.
