At the beginning of the founding of the army, Li Yuan's army was less than 30,000. But as we all know, a thousand troops are easy to get, but one will be hard to find. Tang Gaozu's identity doomed his men to gather. This means that among all organizations, Li Yuan's insurgents have the most potential. This also laid a solid foundation for his future achievements. Li Yuan was born in a noble family. His uncle is Emperor Wendi of Sui Dynasty, the great-grandfather of Sui Dynasty. His cousin is Emperor Yang Di and Emperor Yang Di. Li Yuan's lofty position and special background became an important factor in his achievements. It is much easier for him to use his position to summon heroes and nobles. This is an absolute advantage over other rebels.
Li Yuan was born in a noble family and received a good education since childhood. Therefore, Tang Gaozu is not inferior to others in knowledge and art of war. Besides, according to records, Li Yuan was a brave and cunning man. During the uprising, he could not have unified the whole country so quickly without proper strategies.
Tang Gaozu, under the banner of "settling everything", Yang Guang usurped the throne and practiced tyranny, which made the people angry. Lao Li restored the orthodoxy of the Sui Dynasty for a great uncle, so please join me in blowing Yang Guang away and helping Yang Dong.
Although Li Yuan's banner is self-deception, don't forget that it will give those who have grass in their hearts an excuse: working with Lao Li is not illegal, for the people of the world and for the country. Therefore, under this slogan, Li Yuan can at least establish a broad United front.
After surrounding Chang 'an, Li Yuan's army did not rush to attack Chang 'an, but strictly carried out military orders: soldiers were not allowed to leave the barracks without authorization and were not allowed to rob nearby villages. At the same time, China people were sent to the city gate to attract the garrison troops in the city to complete their intentions, but Tang gaozu was kind-hearted and the garrison troops turned a deaf ear. Li Yuan ordered his army to attack the city. Attack Chang 'an with Li, Li and Li. Soon Lei Yongji, the leader of the army, took the lead in boarding Chengtou, and Chang 'an was conquered.
