Speaking of which, we have to say, Fu Lin's arrangement is also normal? There's nothing, that is, you only look at the surface problems, in fact, there are more problems.

Jia Xu, who was beside Fu Lin, was also smiling and brushing his beard, and at this time, Fu Lin turned his head to him and said, "Wenhe, what do you think of my arrangement?" Are there any questions? ’

When Jia Xu heard the lord's question, he also said seriously: "The lord's arrangement is decent and foolproof, it's just ......"

Obviously, Jia Xu has not finished speaking, and Jia Xu is still so cautious, this may be a person's habit, a person's principle of dealing with the world, unless there are special circumstances, otherwise, he will not change until he dies.

And Jia Xu's appearance, Fu Lin has long been used to it, so Fu Lin continued: "Wenhe, if you have anything to say, just say it, between you and me, do you still need to be so careful?" ’

Jia Xu also smiled bitterly, this lord is definitely extraordinary, and he can't hide his thoughts, but this is also a good thing.

With such a capable lord, he will definitely soar in the future, and he will not fall easily, and his children and grandchildren will also be able to get a stable life.

So, thinking of this, Jia Xu also smiled and continued: "The lord is wise, his subordinates and others, what thoughts do they have, they can't hide it from the lord, in fact, the subordinates feel that the lord's arrangement is too decent, just to hold the Yellow River crossing, Yan Liang's army, otherwise it is not easy to cross the river, but the war will be protracted, we just got Luoyang, Luoyang City is even more people's hearts, there are many people with other thoughts, have ideas about the lord, so, subordinates have an idea, if ......'

When Jia Xu said this, and was about to continue, he heard Fu Lin immediately interrupt Jia Xu's words, and then said: "Wenhe, don't say your strategy and ideas first, see if my thoughts are the same as your strategy, I think so, you are south of the Yellow River, leading the army to be stationed again, doubting the enemy, I led the Qilin Guard, bypassing the Yellow River from the west, in the Taishang Mountain north of the Yellow River, sending troops to attack Yan Liang, we took the wolf smoke beacon fire as the number, and attacked Yan Liang on both sides, in order to defeat Yu Yan Liang's soldiers and horses, what do the military advisors think?" ’

Fu Lin, it has been a long time since he called Jia Xu a military advisor, and he suddenly called Jia Xu like this today, which also made Jia Xu feel a sense of intimacy that he had not seen for a long time.

And speaking of this, we are in a hurry, we have to introduce Taihang Mountain, everyone should not throw eggs, but be patient, because after all, there are people who do not know the existence of Taihang Mountain? While this is a minority, there are exceptions.

Taihang Mountain, also known as Wuxing Mountain, Wangmu Mountain, and Nuwa Mountain, is an important mountain range and geographical demarcation line in eastern China.

Located between Shanxi Province and the North China Plain, spanning Beijing, Hebei, Shanxi, Henan four provinces and cities, the mountain range starts from Xishan in Beijing in the north, extends to Wangwu Mountain in the border area of Henan and Shanxi in the south, connects the Shanxi Plateau in the west, and borders the North China Plain in the east, showing a northeast-southwest trend, stretching for more than 400 kilometers.

Taihang Mountain is composed of a variety of rock structures, presenting different landforms, most of them are above 1,200 meters above sea level, there are many rivers originating or flowing through, the terrain is high in the north and low in the south, and there are rich coal resources in storage.

Taihang Mountain is one of the second and third tiers of Chinese topography, and it is also the dividing line between the Loess Plateau and the North China Plain.

600 million years ago, the Taihang Mountains area was a vast ocean, and later experienced frequent crustal activities, the ground

When the sea recedes, the swamps here are widespread, the climate is warm and humid, and dense forests grow, so the rich coal resources in the Taihang Mountains have been formed. Later, the earth's crustal activities gradually uplifted the Taihang Mountains. Later, it broke off with the Great Plain of North China in the east and west, forming a steep landform in the east and a gentle landform in the west.

About 2.4 million years ago, it began to bulge and gradually formed. As early as 2.8 billion years ago, the Taihang Mountains area was submerged by seawater, depositing huge thick clastic rocks, iron-bearing siliceous rocks and carbonate strata, affected by the Wutai movement and the Luliang movement, the ancient strata in the area generally suffered from folding, metamorphism, and accompanied by faults and quartzite intrusion. In the 21st century, 1.8 billion years ago, a crystalline basement layer of mixed lithification was formed.

After the Luliang Movement in the 21st century, which was 1.8 billion years ago, the crust in this area entered a stage of differential elevation and elevation, which led to the reciprocal and reciprocal sedimentary caprock of the Mesoproterozoic platform, and the overlying Cambrian, Ordovician, Carboniferous and Permian strata of the Paleozoic. Among them, Ordovician and Permian are coal-bearing strata. The Yanshan movement that occurred in the Mesozoic caused the Neo-Huaxia fold belt of the Taihang Mountains to gradually form and develop the deep fault zone in front of the Taihang Mountains.

The Himalayan movement that occurred in the Cenozoic era made the Taihang Mountain rise strongly, and the North China Flat principle in front of the mountain was relatively sinking, and after millions of years of tempering, the Taihang Mountain finally came into being.

The mountainous area is cut by Juma River, Hutuo River, Zhanghe River, Qin River, etc., and there are many horizontal valleys, which are called "陉" locally, and have the name of "Taihang Eight Mountains" in ancient times, and are important passages for east-west traffic. In the fault basin of the eastern wing of Taihang Mountain, there are famous coal mines such as Jingcheng, Lincheng, Fengfeng, and Liuhegou. The Taihang Mountains are an important geographical boundary, the Loess Plateau is to the west of the mountain, and the Huang-Huai-Hai Plain is to the east. The mountainous area has an obvious blocking effect on the summer monsoon, and the windward slope has more precipitation and forms a rainstorm area. The eastern side of the mountain is a zone of strong seismic activity.

The geological base of the Taihang Mountains is a compound monoclinic fold. The east side is a fault structure, with a relative height difference of 1500~2000 meters, and a typical alluvial fan and alluvial plain are developed in front of the mountain. From north to south, there are peaks such as Xiaowutai Mountain (2882 meters above sea level), Taibai Mountain, Baishi Mountain, Langya Mountain, Nantuo Mountain, Yangqu Mountain, and Wangwu Mountain. The rivers in the eastern part of the Shanxi Plateau mostly cut through the Taihang Mountains into the Hebei Plain and flow into the Haihe River system. Only the Qin River system in the southwest joins the Yellow River in the south.

Taihang Mountain is an important geographical boundary in eastern China. The North China Plain in the east is a deciduous broad-leaved forest zone, and the Loess Plateau in the west is a forest-steppe zone and a steppe zone, and there are obvious differences in the characteristics of vegetation and soil vertical zones on both sides.

The Taihang Mountains are mostly east-west horizontal valleys, which have been traffic arteries and business travel thoroughfares since ancient times. In ancient times, there was the famous "Taihang Eight Mountains".

Taihang Mountain is high in the north and low in the south, and most of them are above 1,200 meters above sea level. The peaks above 2,000 meters include Xiaowutai Mountain, Ling Mountain, Dongling Mountain, Baishi Mountain in Hebei, Taibai Wei Mountain, Nansuo Mountain, Yangqu Mountain in Shanxi, etc. The highest peak at the northern end is Xiaowutai Mountain, with an altitude of 2,882 meters; The southern peak is Fozi Mountain and Banshan Mountain in Lingchuan, with an altitude of 1,745 meters and 1,791 meters respectively.

The Taihang Mountains are steep in the east and gentle in the west, and the rivers in the eastern part of the Shanxi Plateau cut through the Taihang Mountains and enter the Hebei Plain and flow into the Haihe River system. Only the Qin River system in the southwest joins the Yellow River in the south.

The west flank of the Taihang Mountains connects the Shanxi Plateau, and the east flank transitions from middle mountains, low mountains and hills to plains. There are many Xiongguan in the mountains, the famous ones are Bauhinia Pass in Hebei, Niangzi Pass, Hongti Pass, Huguan Pass, Tianjing Pass and so on in Shanxi.

The Taihang Mountains are the natural dividing line between the Loess Plateau and the North China Plain. Shen Kuo, an outstanding scientist in the Northern Song Dynasty, saw that between the cliffs of Taihang Mountain, "the cowardly snail shells and stones are like bird eggs, and the stone walls are like belts", and pointed out after research: "This is the seashore of the past, and the east is nearly a thousand miles away from the sea today."

Modern geological studies have confirmed his assertion. The snail shells between the cliffs of Taihang Mountain are fossils of brachiopods or mollusks in the Paleozoic strata.
