The second chapter of Romance of the Three Kingdoms was mainly about the story of Cao Cao launching the Battle of Red Cliff, where Sun Quan and Liu Bei joined forces to resist Cao Cao. The original text was as follows: Cao Cao sneaked out at night to see Sun Quan and Liu Bei at the foot of Red Cliff. He called out to Sun Quan, saying,"General Sun, I have broken through this city. You can offer this place to thank me for your service." Sun Quan replied,"What do you mean?" Cao Cao said,"If I want to capture the enemy, I must first capture the king. If I attack the city, I will first break your army. Therefore, please break my army first." Sun Quan and Liu Bei formed an alliance to attack Cao Cao together. Cao Cao saw that the situation was not good, so he took out his spear and prepared to fight with Liu Bei. He had no time to lead the army to escape. Liu Bei took advantage of the victory to pursue and defeat Cao Cao. At this time, Cao Cao returned on horseback and saw that Sun Quan and Liu Bei had been defeated. He was filled with regret.
