Departing from Dading Prefecture, passing Gaozhou, crossing the Cang'er River, he arrived in Fengzhou. Fengzhou's Zhangmin Palace, like Gaozhou, is the head-seated military prefecture of the Khitan Geowuduo. This is the case in many places near Linhuang Prefecture. The head-seated military prefecture is the private land of the Khitan princes and nobles, and they are responsible for the officials and taxes, and are not affiliated with the Khitan court. In a sense, this is the feudal tradition of ancient times, and the Central Plains has long disappeared.

The nine Oludo had been eliminated in Dading Prefecture, and the troops of the military states under their rule were insignificant to the Song army. Almost without any blood, the Song army entered Fengzhou. The nearby prefectures and counties were also sacrificed to the city.

After entering the city gate, Du Zhongxiao raised his eyes to see. He saw that there were few pedestrians on the street and it seemed a little deserted. A small number of shops on the street were closed, most of them were still open, and there was nothing unusual. However, although the shops were open, the business was not good.

After arriving at the prefecture, Du Zhongxiao sat down. Jia Kui brought two officials over and greeted Du Zhongxiao.

After the ceremony, Jia Kui pointed at a person and said, "This is Yelu Aci, the governor of Fengzhou. My army has arrived and opened the door to offer the city."

Du Zhongxiao nodded and asked A Ci: "When I just entered the city, I saw that the city was deserted. What's going on? It's the official road here, so it should be extremely prosperous. Although most of the shops along the street are open, I can't see a few customers."

A Ci bowed and said, "When I heard the arrival of the army, many nomadic tribes nearby went to the mountains. I heard that some tribes would migrate northward to avoid the imperial army. Originally, the Han and Khitans lived in the city, and many Khitans fled, and most of the remaining Han people in the city were Han people. The number of households decreased a lot, so they naturally became deserted."

Du Zhongxiaoqi said: "Have the Khitans escaped? I haven't heard of it all the way."

A Ci said: "The land is located in the north, and there are many nomadic people everywhere, so it is naturally different from the south. If the people who farm the fields do not leave, where can they escape? Nomadic people are different. As long as there are water plants, they can migrate."

"So that's it." Du Zhongxiao nodded. After crossing the Cang'er River, there were fewer and fewer farming, and the number of nomadic people gradually increased, which was completely different from the Dading Prefecture area. Only some arable land near the city, mostly Han and Xi people farmed. Most of the Khitans were landlords, hired people to cultivate land, or lived together to grazed cattle and sheep on the grass. Grazing was much more free, and this area was mountainous, and many tribes fled into the mountains.

After asking about some things in the city, Du Zhongxiao asked A Ci to leave and called Zhao Zi and Wang Kai.

The four of them sat down and Du Zhongxiao said, "After passing Fengzhou, the more north they go, there will be more and more nomadic tribes. Just now, the magistrate of Fengzhou said that many nomadic tribes, when they heard the arrival of the army, fled to the mountains. Some even wanted to migrate to the distance."

Wang Kai said: "Where can they move to? We occupied Linhuang Mansion, which is under the control of the capital within hundreds of miles of the surrounding area."

Du Zhongxiao smiled and said, "This is not the Central Plains, hundreds of miles are not a great number. Nomadic people can migrate hundreds of miles a year, which is not a great thing. In fact, if they cannot control their tribes, these herdsmen cannot manage them."

Zhao Zi thought for a while and said, "Taiwei, in this way, even if we occupy the nearby state army, we will have no way to deal with the herdsmen?"

Du Zhongxiao said: "In the past, all dynasties were managed by the inner tribes in these places, so there was a reason. Herders were unable to travel and move, and they did not rely on tribes, and they would not be able to form households and people like the Central Plains. We must find a way to do what we should do."

Jia Kui said: "All the way north, there are tribes who surrender. Taiwei, are we also relying on tribes and in charge of various places?"

Du Zhongxiao sighed: "Things are not that simple. Relying on tribes, one must enfeoff the leaders of the tribe and give them wealth and power. It is natural to be said about the years of peace. How can these people manage them when there is chaos? Moreover, each tribe is united with military and civilians, and has swords in his hands. It is not a good thing for the court. After occupying these places in all dynasties, this problem has been faced. The court needs less trouble, so it can only allow the Hu tribe to be attached to the inner tribes and give the inner tribes the inner tribes. They are united with military and civilians and suppress the land. But once there is chaos in the Central Plains, these internal tribes can contribute less and cause more chaos, which will be difficult to say at that time."

Jia Kui said, "If it were the Taiwei, what should we do? Our army cannot let the local people ignore it."

Du Zhongxiao said: "I don't want to repeat the mistakes of my predecessors, and to be at peace for a while, and to harm future generations. Fundamentally, if you want to make this place stable, you still have to be registered as households and people, otherwise there will be no change in the end. But for a while, households and people cannot be registered as households and people, so wait. These days, wherever our army passes, except for the detective cavalry, they are gathered in the city and inn along the road. Don't harass the herdsmen. If you want to migrate, go with them. Tell me, how many herdsmen can accommodate in a place, the number difference will not be too much. They are willing to give up the place, so that's best."

Zhao Zi said: "Taiwei, these herdsmen will not occupy other places when they move to other places?"

Du Zhongxiao said: "Grafting is different from farming. The grassland is not your home. You can grazing, and I can do it. Who will be born after all, you will have to fight to know. Therefore, the migration of grassland ethnic groups often causes chain reactions, thousands of miles away. Unlike those who farm in the Central Plains, no matter who comes or is there, they will have to come back even if they leave."

In fact, the people of the Central Plains did not come back after leaving. Since the Five Barbarians invaded China, they have moved south through their clothes. However, unlike the grassland people, the Han people have gone south in the past, and the Han people have gone to the development site. When there is no open space and the conflicts have increased, it will be difficult to go south again. The large-scale migration of the grassland people may not be as large as that of the Han people, but farther away. The Han Dynasty developed the Western Regions and the Huns moved westward. If they walked, they were afraid that they would not be thousands of miles away.

After the Khitan was destroyed, the Song Dynasty occupied the territory of the Khitan, which would inevitably cause a chain reaction on the grassland. When the Khitan and the Xi tribe moved westward, some would definitely merge into the Tatars, and some would go westward. Where can they go the westward? God knows.

From Linhuang Prefecture to the north, the continuous Asian grasslands are extremely vast, connecting Eurasia. The expansion of the Song Dynasty to the north will inevitably lead to a large number of grassland ethnic groups moving westward. No one can tell whether the original grassland tribes were affected by it, whether they absorbed these people or drove them to move westward. Moreover, the Tatars in the west are rising, and this change has happened. Who knows what will happen?

Du Zhongxiao couldn't explain it clearly. Before Mongolia rose, disrupting the grassland pattern and the Song Dynasty's strong advance northward advance had never happened in history. Can Mongolia rise? At this time, their strength was insufficient. If they advanced westward, who would be in trouble? Not to mention such a great power, after the Khitan was destroyed by the Jin Dynasty in history, Yelu Dashi brought a small number of tribes to Central Asia to establish the Western Liao Dynasty. At this time, the power of moving westward could be much greater. If they headed westward, could Central Asia's power be blocked? There was no answer.

He shook his head, even with the knowledge of later generations, Du Zhongxiao could not tell the reason. The expansion of the power of the Song Dynasty must have a boundary, and the farthest was to occupy the old land of the Khitan. Later, with the construction of the new railway, it was nothing more than to eliminate the Tatars and other Hu tribes. The farthest place was beyond reach.
