Is the million-strong army in Chinese history just an exaggeration?

What do you think? The "Million Army" would be considered good if it had 100,000 combat troops.

In the Battle of Chibi, Cao Cao claimed to have an 800,000-strong army. In fact, including the defenders in Hebei, there were only 270,000. Those who went south to Jingzhou did not know if there were 100,000. Later, they divided their troops to Hefei to resist. I don’t know if even 50,000 people from Sun Quan’s main force actually reached Chibi.

Cao Cao was attacked head-on by Zhou Yu's navy of more than 10,000 people who came upriver at Chibi, and was forced to retreat to the north bank to garrison in Wulin. He divided the troops into two teams, the front and rear. The rear team trained the navy, and the front team confronted Zhou Yu in Wulin. It was estimated that there were not even 30,000 people.

In the entire Battle of Chibi, Cao’s 800,000-strong water stronghold was attacked and defeated by Zhou Yu’s 10,000-strong naval force. After the 800,000-strong army retreated, it was ambushed and defeated by Liu Bei’s 10,000-strong force. The whole army was almost defeated. Overturned.

This 800,000-strong army is simply a huge joke.
