There was a single chapter before that explained many nouns in a concentrated manner, and this is the second one.

I was having a meeting and was idle, I made a phone call, and I’m sorry for having any questions about typos.

(1) Liaodong refers to Liaodong County. The capital of Xipu era is located in Xiangping (near Liaoyang today), and the general scope includes Liaoyang, Liaoning Province today.

Benxi, Anshan, Yingkou, Dandong, one or most of them, and all Dalian City.

Simply put, it is equivalent to half of Liaoning Province (east and south).

During the Murong era, two sons were allowed to settle in Liaodong, Muronghan Town Xiangping (Liaoyang), and Murongren Town Pingguo (Xiong Yue).

After Pingzhou poured into the Central Plains people in the late Western Jin Dynasty, the population of this county rose to about 150,000. After years of war, some were forced to move, some died, and some fled. Now it is about 100,000, or even less.

In agriculture, Han people mainly planted millet, millet and beans. Because the frost-free period is long and the soil is extremely fertile, the agricultural conditions are good.

After Goguryeo captured this place in history, it vigorously operated throughout the Southern and Northern Dynasties, turning it into its own important agricultural area.

It can be seen from the capture of various places in Goguryeo during the Tang Dynasty. A total of hundreds of thousands of stones of grain, 50,000 horses, 50,000 cattle, and 10,000 Mingguang armor were seized on the territory of Liaodong County.

Li Shimin once suggested to attack Jian'an City (northeast of Gaizhou), because the city had few soldiers and more food. "Jian'an relied on the dangers and had too many grains, but few scholars."

Liaodong County is an important agricultural area in Goguryeo, a large grain producer and an important animal husbandry area.

During the entire Little Ice Age of the Northern and Southern Dynasties, Goguryeo expanded into a warm area, and Liaodong was its focus. The main battles between the Tang Dynasty and Goguryeo were carried out in the Liaodong and Xuan counties.

(2) Xuanwan roughly includes most of today's Shenyang, Fushun and Tieling, and is located north of Liaodong County.

In 645, Li Ji attacked Gaimu City (now near Fushun) and obtained more than 100,000 stones of grain.

This is also an agricultural planting area.

(3) Western Liao is in Tangshan, Hebei today, part of Qinhuangdao, that is, within Shanhaiguan, not the Jinzhou area of ​​the western Liaoning Corridor. The latter is still part of the Liaoze Corridor. The western Liaoning Corridor has not yet accumulated into land, mainly swamps, and it is not easy to use horse and carriages. Cavalry can walk, but logistics is also difficult.

This county belongs to Youzhou administratively.

(4) Lelang, the area of ​​northwestern North Korea, including Pyongyang.

Because the lighting conditions were better than the mountainous areas in Goguryeo, it was occupied by Goguryeo around 313 years ago, but the control was not tight and it was somewhat restrained.

Later, Goguryeo was frustrated and began to focus on operating this area. He fought repeatedly with Baekje. There was also a king who was shot by an arrow while defending the city and died.

Later, Goguryeo moved the capital here.

From the late Pu'un to the early Tang Dynasty, Goguryeo experienced a complete Central Plains and Southern and Northern Dynasties. Because no one cared about it, coupled with the cold climate of the Little Ice Age in the Northeast, it continued to move south and expand, occupying relatively warm agricultural areas such as Liaodong, Xuan, Lelang, and Beltang, and continuously built cities and reclaimed farmland. The population increased from less than 500,000 to about 3.5 million.

There was a joke in later generations. The household registration obtained by the Sui Dynasty destroyed the Southern Chen Dynasty was not as high as Goguryeo. The reason why jokes were jokes was that there were many hidden households in the south of the Yangtze River, and the number on the book was just a number. However, it also shows that Goguryeo had expanded its national strength to a considerable extent after three hundred years of vigorous operation of the two generals and the Southern and Northern Dynasties.

(5) Changli Changli County is located in the later areas of Jinzhou, Chaoyang, Huludao and Fuxin.

Later generations of Changli in Hebei were named after Changli moved to Linyu Pass (Shanhaiguan) during the Tang Dynasty.

The original Changli was outside the pass.

Changli County is closest to the Central Plains and communicates with Beiping County through Lulong Road. At the end of the Jin Dynasty, most people from Hebei went to Changli.

Murong made great resettlement, not only farming, but also growing hemp. It developed very well and was quite good.

This is also the richest county in Pingzhou, where Longcheng is located.

(6) Lu Long Dao This path passes through Youzhou, crosses Yanshan Mountain, and winds along the White Wolf Water (Daling River) valley, entering Changli.

Due to the limitation of terrain, the road conditions are very poor and the traffic capacity is limited.

How to describe it? Just like Youzhou, Pingzhou is connected to blood by only one capillary between the two major organs.

Therefore, during the late Tang and Five Dynasties Little Ice Age, part of the Liaoxi Corridor was silted into land, and the road appeared, Lulong Road quickly retreated to a secondary position.

From then on, it has been modern, and the "surrounding the sea channel" of the western Liaoning Corridor has become more critical.

(7) Pingzhou Pingzhou governs 5 counties and 26 counties in Changli, Liaodong, Xuan, Lelang, and 5 counties in Dafang. Since the Han Dynasty and until the Ming Dynasty, the actual control area of ​​the Central Plains dynasty was basically this area, and immigration has often occurred here.

I think the reason is clear. We can grow food, hemp, and even silkworms (tussalis), and Goguryeo is staring at this place.

Even in the turbulent times of the Northern and Southern Dynasties, the regime controlling Hebei would find ways to control Pingzhou. Even if it was not good, it would occupy Changli and separate the plains and mountainous areas from Goguryeo.

Because you retreated from Changli, Goguryeo will write Youzhou, which is hard to fill in desires and wars are inevitable. So it is better to fight in Changli, Liaodong, and Xuandao.

Anyway, there were many cavalrymen in the Northern Dynasties, and some grassland lands were also inconvenient to transport grain on Lulong Road, so he grazed from the grassland.

When Li Shimin attacked Goguryeo, he mentioned: "Besides, the family has given enough food to live in acres of grain and a red warehouse of millet. Although it is enough to be a military reserve, I am still afraid that I will be busy with luck, so I drive more cattle and sheep to feed my army."

This is a milestone reform in the history of the Tang army's logistics.

Looking at the entire Tang Dynasty, I really liked to recruit cattle and sheep from tribes, allowing them to drive away grazing while following the army as supplies:

Eat milk first, and then eat meat.

The Tang army fought in the Western Regions and even crossed the Tianshan Mountains, which had this bonus.

The reason for writing this is mainly because I found that many readers subconsciously used the Ming and Qing dynasties to cover it before.
