Why did Zhuge Liang always attack one place in the Northern Expedition? What happened?

Zhuge Liang's Northern Expedition always attacked Longyou for three main reasons: there have been many powerful generals in Longyou since ancient times, and the people there are very tough, both men and women; Longyou area is very suitable for raising horses, where many war horses are produced; Longyou area is rich in crops, especially grain.

First, there have been many strong generals in Longyou area since ancient times, and the people there are very tough, both men and women. Longyou area has always advocated force, where the folk customs are particularly tough, and the students who grew up there spent their childhood in battle. They make good use of their strong bodies and are suitable for fighting as soldiers. In the Western Han Dynasty, Longyou was regarded as one of the military fortresses of the Western Han Dynasty to the Huns. There are many famous soldiers there, such as General Li Guang and General Zhao Chongguo. Shu Han needs to be recruited, and Longyou is the best choice.

Second, Longyou area is very suitable for raising horses, where many war horses are produced. Longyou area includes Liangzhou, where good horses have been produced since ancient times. Liangzhou is vast and sparsely populated. Animal husbandry is particularly developed. In the Western Han Dynasty, Huo Qubing always provided soldiers with war horses. In the Eastern Han Dynasty, it was from there that horses were prepared for his soldiers. If Shu Han wants to compete with Cao Wei's army, he must have good horses, so he always wants to win them in Longyou area.

Third, the Longyou area is rich in crops, especially grain, which can provide food and grass for the Shu and Han armies. Longyou area is rich in crops, especially grain. The agricultural construction in Longyou is very good, and the grain output there is particularly high. Xiahou Yuan, Cao Wei's army, once sent troops to Longyou and received a lot of food. And if Zhuge Liang wins Longyou, he can provide food and grass for the Shu-Han army.

To sum up, Longyou area is very rich in products, which can help Zhuge Liang solve all the munitions, troops, horses and food. If Shu Han owns Longyou, their military strength will be greatly improved.
