Because Xiangyang is located in the middle and lower reaches of Kyushu, in the middle of the Yangtze River, and the importance of the Yangtze River obviously goes without saying. It connects Bashu to the left, Jiangdong to the right, the Central Plains to the top and South Vietnam to the bottom. Since ancient times, it has been a strategic location connecting six states, and Xiangyang is also the state city of Jingzhou. Therefore, the economic, cultural, military and strategic geographical location of Xiangyang City is extremely important.

It is just at the crossroads of a basin, which runs through the north and south, and passes through here. Things run through, but also through here. All the roads around are gathered here and can't be bypassed. So whether you build a turret or a barracks here, as long as this mouth is blocked, the whole basin is under your control. Xiangyang is like a thick sputum choking in the opponent's throat, making him depressed and vomiting blood.

Let's put the administrative sign on it and see how awesome Xiangyang's geographical location is.

look south first. From Xiangyang south, along the Yicheng passage between Jingshan (west) and Dahongshan (east), you can go all the way to Jingzhou, enter the vast Jianghan Plain and reach the Yangtze River. Then you can guard Yichang to the west, which is equivalent to locking the entrance of the Three Gorges in Sichuan. To the east, we can hold Jianghan Plain, an important economic zone, in our hands. Chu wants to compete for supremacy in the north, and asks how heavy the tripod of the Central Plains governors is. Xiangyang is its bridgehead. Why did Guo Jing stick to Xiangyang? It was also because once Xiangyang was broken, the Mongols could March in, enter along the Yangtze River, cut off the connection between Sichuan and Jiangnan, and wreak havoc in Jianghan Plain.

What is even more frightening is that the Hanshui River, which originated in Hanzhong, flows southeast here in Xiangyang after crossing Ankang. In ancient times, transportation was inconvenient, and it was self-evident that there was such a river to follow. After the Mongols broke Xiangyang, they entered the Yangtze River along the Han River and captured Ezhou, and the defense system in the Southern Song Dynasty collapsed.

look east again. Xiangyang is east, with Tongbai Mountain in the north and Dahongshan in the south, with Zaoyang to Suizhou in the middle, Anlu from Suizhou and Hankou in the south. To the north, Dawu County can be controlled, which is the western channel of communication between Jianghuai Plain and Yangtze River Basin. There are famous Yiyang three passes around here, Wusheng Pass, Jiuli Pass and Pingjing Pass. Under the two Huainan areas, if you get these three passes, the defenders will collapse, commonly known as the three passes will be destroyed. As soon as Li Zicheng and Zhang Xianzhong hit the three levels, Zuo Liangyu broke up immediately. (self-knowledge) "
