In the sixteenth year of Jian 'an, Liu Zhang followed Zhang Song's advice and sent Fazheng to invite Liu Bei to Sichuan to help him deal with Zhang Lu. Fa Zheng and Pang Tong suggested that Liu Bei take Yizhou. Liu Bei left Zhuge Liang, Guan Yu and others guarding Jingzhou, and went to Shu with tens of thousands of soldiers to meet Liu Zhang in Fucheng. During this period, Zhang Song, Fazheng and Pang Tong all advised Liu Bei to attack and kill Liu Zhang, but Liu Bei refused because things were too hasty.
So I went to the north to germinate, and I planted a stout tree to collect people's hearts. In the seventeenth year of Jian 'an, Zhang Song was killed, and Liu Bei and Liu Zhang turned against each other. Liu Zhang sent Liu Gui, Lingbao, Zhang Ren, Deng Xian and Wu Yi to stop Liu Bei in Fucheng, but they were all defeated by Liu Bei and Wu Yi surrendered.
Liu Zhang sent Li Yan and Guan Fei to Mianzhu, and both of them surrendered. Liu Bei's military strength grew stronger, he sent troops to pacify the counties, and at the same time transferred Zhuge Liang, Zhang Fei and Zhao Yun to lead the army into Shu. Liu Bei marched into Luocheng, and Pang Tong was killed by an arrow when he attacked the city. He is only 36 years old. Luocheng was conquered last year and surrounded by Zhuge Liang, Zhang Fei and Zhao Yun.
When Liu Bei established Ning Du You, Li Hui just said that he would drop Ma Chao. Ma Chao then led the army to the north of the city, and the city was shocked for a while. Liu Bei then sent Jian Yong to say that he had surrendered to Liu Zhang, led Yizhou Pastoral, and enabled many talents. It was the 19th year of Jian 'an (2 14).

Xichuan is easy to defend but difficult to attack since ancient times, and it is rich in products. It is called "Land of Abundance". In the era of the Three Kingdoms, it is a very important strategic move to seize surprisingly.
"Xichuan" as the name of administrative division began in the Tang Dynasty. By 757 AD, the original Jiannan Our Mission was divided into Jiannan Dongchuan Our Mission and Jiannan Xichuan Our Mission. Dong Chuan of Jiannan is called "Dongchuan" for short, and Xi Chuan of Jiannan is called "Xichuan" for short. In the Song Dynasty, Xichuan Road was set up. Since then, the word "surprising" has become a household name.
The word "surprising" in Romance of the Three Kingdoms refers to the whole Yizhou in most cases; Sometimes compared with Dongchuan, it refers to the western region of Yizhou. "Xichuan" in the Tang and Song Dynasties is only a part of today's central and western Sichuan. Liu Bei occupied surprisingly.
In April of the 19th year of Jian 'an (2 14), Liu Bei and Pang Tong had surrounded Cone City for more than a year. Although the scene was beautiful and the initiative was entirely in Liu Bei's hands, they were still noisy outside Cone City, like a crowd of onlookers, with no achievements at all. So Zhuge Liang left Guan Yu to guard Jingzhou, and he took Zhang Fei and Zhao Yun back to the Yangtze River and entered Xichuan.
