Who was singing in the Romance of the Three Kingdoms?

It should be Cao Cao...

"The general's northern granary occupation" should refer to the Wuchao granary in the Battle of Guandu```

" Hu Qin told "The heroic deeds" should refer to Cao Cao's conquest of Yuan Shang and the northern Wuhuan```

"The defeated army moved south and far north" where the "defeated army" should refer to Yuan Shang```

"Chibi "Only 70,000 of our brothers were killed in the fierce battle"

This is further confirmed by Cao Cao's fact that Zhou Yu's total number of troops was only tens of thousands and it was impossible to kill them all.

So it can only be Cao Caojun```

"Waiting for the moment when the beloved returns" The "beloved" may refer to Guo Jia```

But I am not sure```
