Zhuge Liang came out of Qishan six times. Where is Qishan? Why is its military significance so important?

? Everyone must know the story of Zhuge Liang. He was one of the smartest people in the Three Kingdoms period. Brilliant, he devoted his life to assisting Liu Bei and Liu Chan and devoted his life to them. Later generations' evaluation of him is "do your best and die." Just eight words reflect Zhuge Liang's loyalty. When Liu Bei was alive, he made suggestions for Liu Bei and helped Liu Bei defeat the country. After Liu Bei's death, he also defended the country.

After Liu Bei's death, Zhuge Liang devoted himself to the great cause of Shu. Seven captures Meng Huo and six exits from Qishan are all stories that happened later. Zhuge Liang constantly led troops to war, thinking that he could make contributions and expand his territory. The story of his six visits to Qishan is well known so far, so why did Zhuge Liang visit Qishan six times?

Where is Qishan now? How important is its military significance? Let's make a brief analysis. Qishan is now located in Lixian County, Longnan City, Gansu Province, in the northeast of this county and city. This place was one of the places that Shu and Wei fought for during the Three Kingdoms period. Why are they fighting for this place? In fact, the strategic position of this place is very important. Zhuge Liang often attacked Wei from here, and Qishan was actually the main road for Zhuge Liang to enter and leave.

Zhuge Liang can take Wei by surprise and replace it with Qishan, so Zhuge Liang went out of Qishan six times. Moreover, in Qishan, Zhuge Liang can easily supply logistics to the army, because there are waterways around Qishan, and with logistics supply, Zhuge Liang can have the energy to attack Wei. Therefore, the military significance of Qishan is more important, and Zhuge Liang can rely on Qishan to constantly attack Wei.
