First, the empty city plan

Zhuge Liang stationed troops in Yangping and sent his troops to attack Wei Jun, leaving only a few old, weak and beaten soldiers in the city. I suddenly heard that Sima Yi, the viceroy of Wei Jun, led1.5000 troops to attack the city. Zhuge Liang was not afraid of danger, so he ordered to open the city gate and sent someone to sweep it. Zhuge Liang himself boarded the tower, sat up and played the piano, with a calm attitude and melodious piano sound. Sima yi came to the front of the city and was suspicious when he saw this situation. There was an ambush in the city, so he dared not make a deal and ordered his withdrawal.

Second, this debate is full of Confucianism.

Cao Cao's army built a village along the river and prepared to annex Jiangdong. Wu Dong's monarchs and ministers are in doubt and fear, and it is difficult to decide whether to go to war. Zhuge Liang used his strategy to discuss world affairs with his ministers and persuaded them to unite with Sun Quan and Liu Bei against Cao. Just the later Battle of Red Cliffs. This idiom originally refers to arguing with many Confucian scholars and counselors to refute each other's arguments, and later refers to arguing fiercely with many people and refuting each other.

Third, the straw boat borrows arrows.

Zhou Yu embarrassed Zhuge Liang to build 100 thousand arrows in ten days, but Zhuge Liang made an order to finish it in three days. Two days ago, he held his ground and secretly told Lu Su to prepare 20 big ships, each with 1000 men. At four o'clock on the third day, the river was foggy. Zhuge Liang led a boat to Cao Jun Shuizhai, drumming and shouting, and feinting. Cao Jun, afraid of being cheated, ordered archers to shoot arrows in the river. This ingenious plan enabled Zhuge Liang to finish the task as easy as blowing off dust.
