What does Zhuge Liang mean in the joke?

Zhuge Liang (18 1 year -234 101October 8 [1]), whose real name was Kong Ming, Wolong (also known as Long Fu) and Yang Du, Xuzhou (now yinan county, Linyi City, Shandong Province), was born in Shu Han during the Three Kingdoms period.

In his early years, he went to Jingzhou with his uncle Zhuge Xuan. After Zhuge Xuan's death, Zhuge Liang cultivated in Longzhong. [3-5] After Liu Bei visited the Caotang, he was invited to help Liu Bei establish Shu Han. After the establishment of Shu and Han Dynasties, Zhuge Liang was made prime minister and marquis of Wuxiang. He comforted the people at home, showed his manners, appointed officials, followed the system of power, was sincere and fair, and joined forces with Wu to resist Wei. In order to realize the political ideal of reviving the Han Dynasty, he made several northern expeditions, but failed due to various factors. Finally, he died in Wuzhangyuan (now Qishan, Baoji, Shaanxi) after being established in Shu Han for 12 years. Liu Chan regarded him as a loyal minister, and later generations often regarded Zhuge Liang as a loyal minister and Zhuge Wuhou. Because of his military ability, the Eastern Jin regime named him King Wu Xing [6].

The representative works of Zhuge Liang's prose include A Model and A Book of Commandments. He once invented the wooden ox, the flying horse, the Kongming lantern and so on, and transformed the crossbow, called Zhuge Lian crossbow, which can hit all targets with one crossbow. Zhuge Liang is the representative of loyal ministers and wise men in China traditional culture. He devoted himself to his life and died. [7]
