Throughout the history of China, cities and ports that are "the throat of Eritrea" and "both political and economic" will become battlegrounds for military strategists! In addition, in the history of China, there are countless examples of military and war being affected by geographical conditions. First of all, look at the overall situation. For example, why did the Central Plains dynasty build the Great Wall on the border to resist the invasion of nomadic people in the north? When the surrounding ethnic groups invaded the Central Plains on a large scale, why did the two sides often take the Qinling Mountains and Huaihe River as the boundary? Why do warlord regimes often appear in Shanxi Plateau, Guanzhong area, Sichuan Basin, Jiangnan area, Fujian area and even Lingnan area? Secondly, from a small point of view, why the gains and losses of Yanmenguan, Jiayuguan, Niangziguan, Caishiji and Jiange Road are always related to the whole war pattern.

The risk is usually "the throat of a certain place in Eritrea", which can be said to be "one person is stronger than ten thousand people". Therefore, such risks have certainly become a battleground for military strategists. As follows:

Shanxi is a mountainous province, belonging to the Loess Plateau, with Taihang Mountain in the east, Luliang Mountain in the west, Zhongtiao Mountain in the south, Yumai Mountain and Hengshan Mountain in the north and Taiyue Mountain in the middle. In addition, there are Wutai Mountain, Taohong Mountain and Department of Zhoushan. The Yellow River flows through the west and south. In Shanxi, the mountains are undulating and the valleys are staggered. There are many collapsed basins and gullies cut by rivers on the mountain. Due to its geographical location, there are many passes in Shanxi, which has become a battleground for military strategists in history.

Shanxi shiguan

Niangziguan

Niangziguan, formerly known as "Weizeguan", is known as "the ninth pass in the world". The female soldiers led by Princess Pingyang in the Tang Dynasty were stationed here, hence the name. It was during his stay in War of Resistance against Japanese Aggression that Niangziguan played an important defensive role.

Yanmenguan

Yanmenguan, also known as Xisongguan, has an old saying that "there are nine pieces in the world, and Yanmen is the first". Li He, a poet in the Tang Dynasty, wrote the poem "Wild Goose Gate Taishouxing" for this purpose. The story of "Yang Jiajiang" made Yanmenguan a household name. During the Anti-Japanese War, He Long commanded the famous "Great Victory of Yanmenguan" here.

Ningwu Pass

Ning Wuguan is one of the famous "three passes" in Shaanxi history. It is known as the strategic role of "Datong in the north, Taiyuan in the south, Shaoguan in the west and Yanmen in the east". This was the most frequent war among the three passes in Ning Wuguan, which played an important role in resisting the plundering of nomads by famous farmers.

Mengguan

Mengguan is known as the "West Gate of Shanxi" and is a veritable battleground for military strategists. In ancient times, there was a saying that there was a Niangziguan in the east and a _ _ Pass in the west.

Shahuguan

Killing Tiger Pass, also known as Killing Tiger Pass, is a battleground for military strategists and a famous tax card. Walking at the west exit is also called "West Exit" all over the world. In order to resist the invasion of Mongolia, the Ming Dynasty sent troops from this port many times, hence the name "Shahukou". Later, in order to ease ethnic conflicts, it was officially renamed "Killing Tiger Mouth", which is now "Killing Tiger Mouth".

Fenglingdu

Fenglingdu, the largest ferry crossing on the Yellow River since ancient times, is also a battleground for military strategists. There have been many wars here. In Jin Yong's famous novel The Condor Heroes, fenglingdu is the place where Yang Guo and Guo Xiang meet.
