Li Jing sent Li Yu's cavalry regiment away, and then he was busy holding a meeting to summarize the combat experience, the members of the four staff groups and the personnel outside the cavalry posts who participated in the battle, as well as Wang Gui and Bai Zaixiang and other Youyang generals. The military structure, individual soldier quality, weapons and equipment, tactical tactics, and command and control capabilities of the generals were discussed in depth, and the gains and losses of our army's coping strategies were also summarized.

"The military effectiveness of the Eight Banners system is only based on the customs and habits of the nomadic peoples, and it is highly local, while the external military adaptability is extremely poor." Cavalry staff officer Sun Dewei said.

"In this operation, the elite heavy armored cavalry of the Eight Banners was extremely unfamiliar with the use of firearms, and there was no firearm cavalry, and there was no musket shooting. According to previous information, the cavalry of the Eight Banners was mainly based on traditional armor and sabers, cavalry short-horned bows, and spears. It has been confirmed in this battle that there are no advanced musketeers in the Eight Banners, and our muskets are far from the bow and arrow in terms of range and penetration, and the cuirass of our army not only effectively protects the torso that is the easiest to hit at a long distance, but also saves weight and maintains mobility. The effective armor penetration distance of our muskets is two to three times that of the enemy, and as long as we keep a distance from the enemy, they will suffer a great loss. ”

"Jiannu's horses are mainly Mongolian horses, which have the advantage of adapting to the cold climate of Northeast China, have endurance, tolerate roughage, and are easy to feed. But the disadvantages are equally obvious, the legs are short and the height is low, although it is good to get on / horse, but when slashing and colliding, the weight is low enough and the tall side suffers, our Arabian horses can directly knock them over, and when fighting with weapons, our army borrows the impact momentum of horsepower is greater, if the angle is right, you can directly cut off the opponent's inferior sword, and cut them into two sections. The speed of running is also not good, the most important thing in combat is not endurance, but explosiveness for a period of time, if you win, you can't catch up with our army, and if you lose, you can't run. As long as we equip the Arabian horses of a town, the cavalry of Jiannu is not to be feared. ”

Li Jing stroked his forehead, these animals, I know that Lao Tzu needs to be equipped, do you know how much Arabian horses cost, the Mamluks in Egypt can't afford to equip them, only middle and senior officers are equipped. This time, more than a hundred horses, do you know how much money was paid, and how much silver was spent, and nearly half of the ships died.

"Jiannu's individual physical fitness is significantly better than that of our army, this final battle, the time lasted for a day and a night, our army has fried noodles, a quick swallowing artifact, you can eat a mouthful of fried noodles and a mouthful of snow at any time, our army is replenished with food, but the soldiers of the Eight Banners have not sleeped, have not eaten, and have not drunk water. After a day and night of continuous fighting, our army was already physically exhausted, and Jiannu could still support it, if it weren't for the burning of the large battalion and shaking the morale of the army. At the same time, Li Bingcheng's iron cavalry gave the final blow, and our army was inevitably annihilated. Army musketeer staff officer Wang Yihui concluded.

"There is no way to do this, whether it is Han Chinese, Mongolians, or Jiannu in Liaodong, they are all tall, on average five centimeters taller than northerners, and ten centimeters taller than Jiangnan people. The height of the tall is even worse than the height of a head. This is due to the climate, and the colder the area, the larger the size of the animal. Li Jing said.

"The Eight Banners system arose from a simple natural economic stage, and its combat effectiveness depended on the maintenance of the Jurchen hunting and martial customs. At the beginning of Nurhachi's establishment of the Eight Banners, he had just come out of the long-term melee and safari mode of production, for the northern peoples between the white mountains and black waters, the bow and crossbow sword was a means of livelihood, and the means of life on the horse and archery campaign, the strong physique and the fierce national character were gradually cultivated in daily life, and adult men were often born professional soldiers. The Eight Banners system only needs to effectively organize and dispatch them, and through a very simple way, it can create a military miracle. From this point of view, the establishment of the Eight Banners system itself is actually very simple and primitive, and it lacks the support of a higher level of social economy, nor can it adapt to a high-level social and economic environment. Such a system does not have a future for development. Its disadvantages are very obvious, the same as the Ming Dynasty's guard system, or even more stubborn, the subordinate is the slave of the superior, and the flag owner is the master of the entire flag, it won't be long before the disadvantages of the guard will also appear on the Eight Banners, and it will be quickly corrupted. Zhao Ren analyzed.

"For many ordinary Jurchens, it is not acceptable overnight to transition from not being bound by any organization in the past to being under the jurisdiction of "Niu Lu Ezhen", "Jiala Ezhen" and "Gushan Ezhen" from the bottom to the top, and finally to the banner lord Baylor. Subjectively, he did not consciously accept the motivation of the Eight Banners System, and he did not have much interest in the Eight Banners System from the perspective of knowledge and emotion. There are still contradictions and conflicts between the inherent habits, understandings, and needs of the Jurchen tribes and the goals and discipline of the Eight Banners system. At the same time, after being incorporated into the Eight Banners, the Jurchen people had to bear more onerous tasks than before, such as the construction of castles, the cultivation of grain, and the preparation of boats and chariots. These are all factors that make the Jurchen and Mongolian people have a negative attitude towards the inclusion of the Eight Banners. Therefore, although Nurhachi vigorously appeased and treated the people who came and returned, there would still be a phenomenon of concealing Dingkou and not reporting it, or even fleeing from the banner, which shows that whether they voluntarily surrendered or were defeated and surrendered and were incorporated into the Eight Banners, the various tribes Beile, Taiji, and Zhushen were more or less forced to survive and intimidated by the powerful military offensive of the Eight Banners. This attack on the Sakhalian camp was particularly obvious, the tribal soldiers and the backbone elements of the annexed tribes had a bitter hatred for the Eight Banners, and none of the banner owners dared to ask for it, so this time they had to organize the backbone of the old men of the three Yalu River and the Aries Bone Department separately, ready to consume them in the war. Solve these big problems. We can do something about intelligence. It would be of great value to be able to rebel against some of the Yeh and other leaders of the newly annexed tribes. Director of Intelligence Li Yi said.

"The analysis is very good, although the intelligence department has just been established, but it already has some meaning to open up the situation, the Eight Banners are not monolithic, and the follow-up should strengthen cooperation with the pyramid marketing group/organization, and vigorously support the forces that oppose the establishment of the state, give military secret assistance, and increase their power." Li Jing said.

After the meeting, Nanao Town held a plenary meeting, the representatives of the participants and the four major staff officers made a report, explaining the experience of contact with Jiannu and the details of the battle, from senior officers to ordinary soldier representatives, from different perspectives to tell their own observations and experiences of the war, after the report meeting, the meritorious personnel were awarded medals and bonuses, and promoted. Youyang generals were also invited to attend the meeting. I feel great admiration for this form of Nanao Town, and the sense of honor brought by small medals and medals to officers and soldiers far exceeds the silver tickets issued on the spot.

This is the first time Li Jing has designed a medal, which is modeled after the Qin system and divided into 20 levels of military merit medals. The Qin Dynasty's 20-level military merit title system is divided into 20 levels, namely: first-class public servant, two Shangzao, three hairpins, four not more, five doctors, six official doctors, seven public doctors, eight public passengers, ninety-five doctors, ten left chiefs, eleven right chiefs, twelve left guards, thirteen middle watches, fourteen right watches, fifteen young ones, sixteen / big ones (Daliang made), seventeen car chiefs, eighteen big chiefs, nineteen Guan Neihou, and twenty Che Hou.

The title of the title of the Qin Dynasty is directly written on the medal, and it is generally awarded to the ninth level, and it will only be awarded if you have made a significant contribution above the ninth level. Since then, Li Jing's system has formed a tradition, and veterans with medals on their chests must be treated with courtesy even if the general sees him.
