Song Yang supported the central government of Dahan with Cao Cao as the core to unify Dongchuan and Hanzhong.
Huang Hao contributed to the unification of Nishikawa by the Otsu Central Committee led by Si Mazhao.
Cenhun brought Wu Dong into the unified territory of Jin Dynasty as soon as possible.
These three are heroes who have been praised through the ages!
Only Jiang Gan failed in his attempt to unify the south of the Yangtze River by Prime Minister Cao, and it didn't really play any role in unifying the Chinese nation. (This is the novel Romance of the Three Kingdoms, which has little influence on actual history. )
It can only be said that he played a key role in the formation of Battle of Red Cliffs's post-China tripartite confrontation and separatist regime for decades, and he was a veritable sinner!
Extended data:
Jiang Gan, Zi Ziyi, was born in Jiujiang (now Shouxian County, Anhui Province). Jiang Gan in history was a celebrity at that time, while Luo Guanzhong portrayed Jiang Gan as a clown fooled by Zhou Yu in the historical novel Romance of the Three Kingdoms.
There are many reasons for Cao Cao's failure, but it has a lot to do with Jiang Gan, a pedant who doesn't succeed or fail.
Cao Cao's soldiers in the north didn't learn to fight in the water, but because of Jingzhou's surrender, Cai Mao and Zhang Yun became the commanders of the water army. These two people have lived in Jiangdong for a long time and are familiar with the method of water warfare. Zhou Yu has always been regarded as a confidant and it is difficult to get rid of it for a long time. Jiang Gan volunteered to surrender Zhou Yu and happened to pass by Jiang Lai. Zhou Yu's mischief made Jiang Gan steal the secret letter written by Zhang Cai, which led to Cao Cao's manslaughter of two generals.
However, Zhou Lang could not break Cao Cao's heart. Pang Tong, who took refuge in Jiangdong, came up with a series of tricks, but how can Pang Tong cross the river safely and how can Cao Cao not be suspicious? While Zhou Yu was worried, Jiang Gan came again. It was he who introduced Pang Tong to Cao Cao, who believed in the serial stratagem provided by the famous Pang Tong, which led to the failure of the war.
Jiang Gan crossed the river twice and was caught twice. Not only did Cao Wei's 830,000 troops die, but even Cao Cao himself almost died. No wonder later generations commented that Jiang Gan was a rotten scholar who accomplished nothing.
Jiang Gan: Actually, Jiang Gan is not without learning. He and Zhou Yu have been classmates since childhood, and they are omnipotent in piano, chess, painting and calligraphy. They have already learned the four books and five classics by heart. He has no courage. When the two armies confronted each other, Zhou Yu volunteered and shuttled through the swords and shadows of Cao Wei's envoys, sailing to tell Wu Dong that tens of thousands of troops had fallen.
Especially when crossing the river for the second time, in the face of fierce and narrow-minded commander Wu Dong, he risked his life and death to fight for it. However, he is really a nonsense fool, a bookcase fool with two legs. Although he was full of knowledge, he didn't use the idea at all. He can only do what others doze off. He quickly gave a pillow and finally destroyed the Cao Wei army he was loyal to. ?
It seems that it is one thing for a person to be knowledgeable, and it is another to be able to do things. Although Wei Qing and Huo Qubing, the generals of the Western Han Dynasty, came from humble origins and had little knowledge, they became great generals who defeated the Huns. However, Jiang Gan, who is full of knowledge, did one thing and another, which became the information for future generations to laugh and cry.
