The Tang Dynasty was the prosperous era of ancient China, and Li Shimin, the emperor of the Tang Dynasty, did not build the Great Wall, but succeeded in making the border ethnic minorities bow down to them, and they respectfully called him "Heavenly Khan".
Tang Taizong Li Shimin was a true emperor of the ages, who avoided war with his unique way of governance, signed a bridge alliance with the surrounding ethnic minorities, and made the Tang Dynasty the largest empire in the world.
After Li Shimin launched the Xuanwumen Rebellion, in order to ensure the stability of the Tang Dynasty, he decisively disposed of the crown prince Li Jiancheng and the king of Qi Li Yuanji, and finally Tang Gaozong Li Yuan could only canonize Li Shimin as the crown prince, and then abdicated on August 9, Li Shimin successfully ascended the throne and became emperor.
However, on the second day of Li Shimin's accession to the throne, the Turkic khans of the northern steppes heard about this and immediately gathered 200,000 troops to the south, preparing to attack the Tang Dynasty.
On August 10, the strength of the Turks posed a great threat to Chang'an, the capital of the Tang Dynasty.
On August 24, the Turkic army raided the Weishui Bridge outside Chang'an City, approaching the Beijing Division, and 200,000 iron cavalry lined up on the north bank of Weishui.
However, the young Li Shimin was not overwhelmed by the crisis in front of him, he was calm and calm, and while sending the general Wei Chigong to lead the army to meet the battle, he led Gao Shilian, Fang Xuanling and other six cronies out of the city to negotiate with the Khan on the bank of Weishui.
When he met the Khan, Li Shimin angrily accused the other party of violating the covenant, and then calmly faced the 200,000-strong army without fear. Seeing this, the khan dismounted and saluted, expressing his admiration for Li Shimin's composure and courage.
Li Shimin was not unprepared, he took six people to negotiate, and let the defenders in Chang'an City line up, so as to create the illusion that the troops were strong and strong, and lure the other party to be deceived.
In the end, the Khan was fooled and showed fear. Two days later, they signed a peace agreement on the Weishui Bridge, known as the Bridge Alliance.
