The waves behind the Yangtze River push the waves ahead, and each generation becomes stronger than the last. (Comparing the ages of the main characters, Zhuge Liang, Zhou Yu, Lu Su, Sun Quan, Liu Bei, etc. are much younger than Cao Cao)

Details determine success or failure. (Details such as connecting the ship and borrowing the east wind determine the success or failure of the battle)

Know yourself and the enemy, and you will never be in danger in a hundred battles. (Sun and Liu knew Cao Cao’s army relatively well, and they also knew their naval forces relatively well, but Cao Cao did not understand the strength of Sun and Liu’s combined forces, let alone naval warfare)

Thinking of these, Hope these are helpful to you.
