Tongguan weather 20 1 1

Guanzhong generally refers to Tongguan (Hangu Pass), Xisanguan (Great Earthquake Pass), Nanwuguan (Languan Pass) and Beixiaoguan (Jinsuo Pass Pass). It is located in the middle of Shaanxi Province, including five cities and one district of xi, Baoji, Xianyang, Weinan, Tongchuan and Yangling.

This area is the heart of Shaanxi Plain, and the northern part is the southern edge of Loess Plateau in western Gansu and northern Shaanxi. The tributaries of the Weihe River, which originated in the Loess Plateau, namely the river valleys formed by Luo Jing and Miwa, respectively constitute three river valleys of different sizes in northern Shaanxi, namely Luochuan, Longdong Jingchuan and Qinlongyichang, bounded by Bai Yushan, Ziwuling (Daqiaoshan), Qianshan and Longshan.

As can be seen from the topographic map, if you cross the Yellow River from southwest Shanxi, it seems that there is only one route, from Taiyuan to Linfen, and then to Hejin, which is called Longmen in ancient times. Hejin is located at the main entrance of Binjiang, and the Yellow River is located at the intersection of Fenhe River and Yellow River at the southern foot of Luliang Mountain, with Fenshui in the east and Hancheng in Shanxi Province across the Yellow River in the west.

We can only cross the river from Hejin, but the question is, is the Yellow River that good? In this geographical environment, how should the troops from Jin to Guan cross the Yellow River?

If you bridge, the terrain on both sides of the strait is steep, there is no chance of winning, and you have to risk being wiped out by the army on the other side, so it is completely impossible to bridge.

If it is a ferry, how can ships cross the Yellow River like this, and how many ships can they pass at a time? And there is a big problem, that is, where to land. Where is the ferry?

As far as the fast-flowing Yellow River is concerned, ferries transport troops, and ferries along the way are bound to be related to the assembly of heavy troops. In terms of traffic volume, the number of soldiers transported at a time must be several. Isn't this the gourd doll who saved grandpa and sent them one by one?

It is even more impossible in the northern part of Guanzhong Plain. On the vast loess plateau, the army's actions are extremely slow and the logistics are unsustainable. Speaking of Guan Zhong, he is already an exhausted teacher. How does it play? To sum up, if we could cross the Yellow River from the southwest of Jinzhong and enter the customs, the great strategists would have done so long ago, and we would not only attack Tongguan (Hanguguan).
