Idioms and allusions
In the Eastern Han Dynasty, Cao Cao forced the princes to attack Sun Quan and Liu Bei. The battle of Chibi was defeated, and after a rest, he led his army to the south to attack Wu again. Sun Quan called together his ministers to discuss the countermeasures. Counselor Zhang Zhao thought that Liu Bei must be united and asked to send troops to fight against Cao. Liu Bei was the son-in-law of the eastern Wu Dynasty, and Cao Cao was their common enemy. It was incumbent on them to fight against Cao!
