During the Three Kingdoms period, Shu was destroyed by Si Mazhao in 263 AD. In 263 AD, Si Mazhao, the prime minister of Wei, sent Zhong Hui, Wargo and Zhuge Xu to Shu Han in Nanping, where they fought a tug-of-war with General Jiang Wei. Wei Jun was blocked by Jiange Army, and Wargo took a flat road to Fucheng and advanced on Chengdu. The late ruler surrendered and was destroyed by Wei.

In 280 1 month, Sun Hao was appointed as prime minister, and led Ku Lokshin and Sun Zhen to cross the river to resist Wang Hunjun, but they were all defeated and died. Wang Zhuo's army cooperated with other Jin Jun along the Yangtze River and captured Xiling, Jiangling, Wuchang and Xunyang. Du Yu also captured the south of Jingzhou. On March 15, Sun Hao saw that 8 Jin Army had surrounded Jianye. He thought that the tide was over and surrendered. Sun Wu perished, and the Western Jin Dynasty unified the world, thus ending the Three Kingdoms period.

Reasons for the demise of Shu:

In the late Shu-Han period, Jiang Wei's Northern Expedition made Shu-Han's national strength consume greatly. Eunuch Huang Hao, Zhuge Liang's son Zhuge Zhan and veteran Zhang Yi all began to oppose Jiang Wei's Northern Expedition. Jiang Wei felt great pressure and dared not go back to Chengdu. He settled down in the pile, reserved military resources and continued to plan the Northern Expedition. On the other hand, Zhuge Zhan and others also want to get rid of Huang Hao, but because Liu Chan likes Huang Hao very much, there is nothing they can do.

In the sixth year of Jing Yao (263), Jiang Wei got the news that Zhong Hui was in charge of the army in Guanzhong. In the above table, Liu Chan sent Zhang Yi and Liao Hua to garrison the danger. However, Huang Hao listened to the ghost and told Liu Chan that the enemy would not come, and Minister Shu Han didn't know about it. It was not until Wei Jun cut Shu and invaded Hanzhong that Liu Chan sent Yi Cheung and Liao Hua to rescue him, but it was too late.

Jiang Wei blocked Zhong Hui's army in Jiange. Unexpectedly, Wargo attacked Mianzhu from Jinggu Road and defeated Zhuge Zhan. On the one hand, Liu Chan mobilized Yan Yu to support Chengdu, on the other hand, he called his ministers to discuss. Qiao Zhou urged Liu Chan to surrender. After receiving the imperial edict from Liu Chan, Jiang Wei tried to restore the country with the help of Zhong Hui, but the plan leaked out and Jiang Wei, Wargo and Zhong Hui were all killed. Since then, Shu Han has completely perished.
