Why was Li Shimin able to defeat the Heyday Turks? The battle will be like a cloud, and the individual soldiers will be the strongest in the world!

Speaking of Li Shimin, the emperor, everyone will definitely think that he is a generation of male lords, and indeed, although Li Shimin is not in the right position, his ability is obvious to all. The rule of Zhenguan allowed the Tang Dynasty to slowly begin to develop from the chaos of the late Sui Dynasty to a prosperous era of economic prosperity and military prosperity. In the countries surrounding the Tang Dynasty, the most influential was the Turkic forces, the Turks had The Eastern Turks and the Western Turks, but our main enemy was the Eastern Turkic forces. After Li Shimin's Xuanwumen Mutiny, the leaders of the Eastern Turks saw an opportunity and sent troops to attack the Tang Dynasty. But he was scared away by Li Shimin's suspicious tactics.
After sending away this greatest enemy, Li Shimin began to plan a plan to destroy it. The first is to contact the Xueyantuo tribe in the north of the Eastern Turks. Then use divisive tactics to split the interior of the Eastern Turks. Cause discord between Jieli Khan and Tuli Khan. In addition, Li Shimin has quite a few elite generals under him, such as Li Jing, the God of War of the Tang Dynasty, whom we are familiar with, who has never tasted defeat in his life, and he is a real victorious general. In addition to him, there are also good generals like Li Shiji, Li Daozong, Xue Wanche and so on.
Although the Eastern Turks at that time were in their heyday, he was still a little tender in the face of such a master as the Tang Dynasty. Tang Taizong's move to divide the enemy, strengthen himself, and unite the enemy of the enemy made the Eastern Turks repeatedly inferior in their confrontations with us. When fighting against the nomads, the Han people feared their cavalry the most, but the cavalry of the Tang Dynasty was not weak at all compared to them, and Li Jing once led 10,000 cavalry to raid Yinshan. Directly annihilated all the troops of Jieli Khan, leaving only Jieli Khan to escape.
In addition to the bravery of the generals and the correct strategy, the Military System of the Tang Dynasty also made the Tang Army's combat effectiveness amazing. After Li Shimin became emperor, the Tang Dynasty implemented the prefectural military system, and anyone who participated in military service would be exempted from the family's taxes, which made many families willing to become soldiers. However, not everyone can become a soldier and be exempt from taxes, and if you want to be a soldier in the Tang Dynasty, you must have excellent physical fitness. Although it will not be as strict as the Wei Wu pawns in the previous Warring States period, there are many requirements for conscription, such as weapons and equipment, horses, grain and grass that need to be supplied by their own families.
And the Tang Dynasty established a military merit system similar to the Qin Dynasty, but it was not as harsh as the Qin Dynasty. As long as they made meritorious service on the battlefield, they would be knighted, freed from the peasant class. The Individual Equipment of the Tang Army was very large, and the common ones were horizontal knives, crossbows, horses and spears. From near and far, it could inflict a wide range of lethality on the Turkic cavalry. Advanced equipment coupled with the command of famous generals, coupled with the temptation of military merit, many Tang troops were very aggressive when fighting, and it was normal for the Turks to fight.
