Zhuge Zhan was the son of Zhuge Liang. Zhuge Liang was old enough to have a son, and when Zhuge Zhan was born, Zhuge Liang was already 46 years old.
Zhuge Liang wrote the Book of Commandments to Zhuge Zhan before his death. After Zhuge Liang's death, Zhuge Zhan attacked the Marquis of Wuxiang. When Zhuge Zhan grew up, he took the daughter of the later lord Liu Chan as his wife and became Liu Chan's son-in-law and the horse of Shu Han.
Because the Shu Han people all miss Zhuge Liang, and Zhuge Zhan is proficient in calligraphy and painting, and his thinking is quick, so everyone likes Zhuge Zhan. Therefore, Zhuge Zhan's has been over-exaggerated, and some of them are exaggerated.
Jiang Wei was Zhuge Liang's apprentice, and during Zhuge Liang's first Northern Expedition, he surrendered Jiang Wei, and after Zhuge Liang's death, he passed on the art of war to Jiang Wei. Jiang Wei was a general of the Shu Han Dynasty and controlled the military of the Shu Han Dynasty. Politically, Jiang Wanfeiyi successively ruled. During the reign of these two men, Jiang Wei did not have any major military moves, but after the death of Jiang Wei, Jiang Wei began his Northern Expedition, carrying out a total of nine Northern Expeditions, with three victories, three draws and three defeats.
Zhuge Zhan and others believe that Jiang Wei has gone out on expeditions many times, resulting in domestic fatigue. So he gave the table to Liu Chan and asked to cut Jiang Wei's military power. Zhuge Zhan was Zhuge Liang's son, and he had always regarded himself as Zhuge Liang's heir, and if he wanted to control the political situation of Shu Han, he may also have selfish intentions and did not want an outsider to steal his limelight.
In 263, the Wei general Deng Aiqi attacked Yinping and appeared in the rear of Shu Han, but because Jiang Wei was fighting in the front, he could not return for a while. Zhuge Zhan then led his army to resist. Zhuge Zhan's eldest son, Zhuge Liang's eldest grandson Zhuge Shang, was nineteen years old at the time, and when he heard that Zhuge Zhan led an army on a campaign, he said that his father was a general and his son was willing to be a pioneer. Enlisted in the army. Before the war, Zhuge Zhan said sadly, "I can't get rid of Huang Hao internally, I can't balance Jiang Wei externally, I can't defend the land when I march, I have three sins, what face can I go back?!" So he held his ground and prepared for a decisive battle.
Zhuge Zhan set up a position in Mianzhu to wait for Deng Ai, and after a big battle, Zhuge Zhan, Zhang Zun and others were killed. Zhuge Zhan's son Zhuge Shang heard of the defeat of the army and also rushed into the battle and died.
In addition, it is said that Chen Shou was once humiliated while serving under Zhuge Zhan, so he framed Zhuge Zhan in the Romance of the Three Kingdoms and exaggerated his faults, which cannot be verified.
